Model: GPT-4
Avatar of the person chatting

I have a wordpress website where I publish photos I take. To add photos to my posts I use the Image block that is provided by WordPress by default. I would like to create a WordPress plugin that enhances the Image block as follows: 1. Add a button to the block sidebar, under the `ALT TEXT (ALTERNATIVE TEXT)` text area. 2. Upon clicking the button, I want to use the GPT4 API to analyze and generate a description of the image in english, and input the description in the ALT TEXT text area.

To create a WordPress plugin that enhances the Image block according to your requirements, you can follow these steps:

  1. Set up a new plugin:

Create a new folder in your WordPress installation's /wp-content/plugins/ directory. Name the folder something like gpt4-image-alt-text.

Inside this new folder, create a file called gpt4-image-alt-text.php. Add the following code to initialize your plugin:

phpCopy code
<?php /** * Plugin Name: GPT-4 Image Alt Text * Description: Enhance the default WordPress Image block by adding a button to generate image descriptions using the GPT-4 API. * Version: 1.0 * Author: Your Name * License: GPL2 **/ if (!defined('ABSPATH')) { exit; }
  1. Enqueue the necessary JavaScript:

Create a new file in the same plugin folder and name it gpt4-image-alt-text.js. This file will contain the JavaScript code to enhance the Image block.

In gpt4-image-alt-text.php, add the following code to enqueue the JavaScript file:

phpCopy code
function gpt4_image_alt_text_enqueue_assets() { wp_enqueue_script( 'gpt4-image-alt-text', plugins_url('gpt4-image-alt-text.js', __FILE__), array('wp-blocks', 'wp-editor', 'wp-element', 'wp-components'), filemtime(plugin_dir_path(__FILE__) . 'gpt4-image-alt-text.js'), true ); } add_action('enqueue_block_editor_assets', 'gpt4_image_alt_text_enqueue_assets');
  1. Modify the Image block:

In gpt4-image-alt-text.js, add the following code to extend the Image block:

javascriptCopy code
const { createHigherOrderComponent } = wp.compose; const { Fragment } = wp.element; const { registerPlugin } = wp.plugins; const { PluginSidebarMoreMenuItem, PluginSidebar } = wp.editPost; const { InspectorControls } = wp.blockEditor; const { Button } = wp.components; const addGPT4Button = createHigherOrderComponent((BlockEdit) => { return (props) => { if (props.name !== 'core/image') { return <BlockEdit {...props} />; } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () => { // Call GPT-4 API to get the description and set the alt text. const description = await getGPT4Description(url); setAttributes({ alt: description }); }; return ( <Fragment> <BlockEdit {...props} /> <InspectorControls> <Button isSecondary onClick={generateAltText} disabled={!url} > Generate Alt Text with GPT-4 </Button> </InspectorControls> </Fragment> ); }; }, 'addGPT4Button'); wp.hooks.addFilter( 'editor.BlockEdit', 'gpt4-image-alt-text/add-gpt4-button', addGPT4Button );
  1. Call the GPT-4 API:

In gpt4-image-alt-text.js, add a new function called getGPT4Description that makes a request to the GPT-4 API:

javascriptCopy code
async function getGPT4Description(imageUrl) { const apiKey = 'your_api_key_here'; const prompt = `Describe the following image in English: ${imageUrl}`; const response = await fetch('https://api.openai.com/v1/engines/gpt-4/completions', { method: 'POST',
Avatar of the person chatting

Please continue exactly where you left off.

Continuing with the getGPT4Description function:

javascriptCopy code
headers: { 'Content-Type': 'application/json', 'Authorization': `Bearer ${apiKey}`, }, body: JSON.stringify({ prompt: prompt, max_tokens: 30, n: 1, stop: null, temperature: 0.8, }), }); const data = await response.json(); const description = data.choices && data.choices[0] && data.choices[0].text.trim(); return description; }

Don't forget to replace 'your_api_key_here' with your actual GPT-4 API key.

  1. Activate the plugin:

Once you've completed the steps above, go to your WordPress admin panel, navigate to "Plugins" and activate the "GPT-4 Image Alt Text" plugin.

Now, when you edit an image block in the block editor, you should see a "Generate Alt Text with GPT-4" button in the block sidebar under the ALT TEXT (ALTERNATIVE TEXT) text area. Clicking the button will generate a description using the GPT-4 API and set it as the image's alt text.

Please note that I used GPT-4 in this example, but since GPT-4 is not available yet, you will need to use GPT-3 or any other version of GPT that is available to you. Make sure to adjust the API endpoint and other parameters according to the API documentation provided by OpenAI.

I have access to GPT4

Great! If you have access to GPT-4, you can use the code provided in the previous steps. Just make sure to replace 'your_api_key_here' with your actual GPT-4 API key and update the API endpoint if necessary, according to the documentation provided by OpenAI.

Once you've completed all the steps and activated the plugin, you should be able to see a "Generate Alt Text with GPT-4" button in the block sidebar under the ALT TEXT (ALTERNATIVE TEXT) text area when editing an image block in the WordPress block editor. Clicking the button will generate a description using the GPT-4 API and set it as the image's alt text.

After installing and activating the plugin, the button does not appear

I apologize for the confusion. Let's debug the issue and make sure the button appears as intended.

  1. Check the browser console for errors:

Open your browser's developer tools (usually by pressing F12 or Ctrl+Shift+I) and navigate to the "Console" tab. Look for any error messages related to your plugin. Errors may provide insight into what is causing the issue.

  1. Verify the JavaScript file is enqueued and loaded:

In the browser's developer tools, go to the "Network" tab, and filter by "JS". Look for gpt4-image-alt-text.js in the list of loaded JavaScript files. If it's not present, there might be an issue with the enqueuing process in your PHP code.

  1. Ensure the block editor is loading the latest version of your JavaScript file:

Sometimes, the browser may cache older versions of your JavaScript file. To ensure you're loading the latest version, you can do a "hard refresh" by pressing Ctrl+Shift+R (Cmd+Shift+R on Mac) or by clearing your browser cache.

  1. Revisit the JavaScript code:

Double-check the gpt4-image-alt-text.js file to ensure the code is correctly entered and formatted.

If none of these steps resolve the issue, please provide any error messages or additional information to help identify the problem, and I'll do my best to assist you further.

I get the following error in the console: Uncaught SyntaxError: Unexpected token '&lt;' (at gpt4-image-alt-text.js?ver=1679184142:11:20)

This error indicates that there is a syntax issue in your gpt4-image-alt-text.js file at line 11, column 20. The error message suggests that an unexpected '<' token is causing the issue.

I suspect the problem is related to using JSX syntax in the JavaScript code without transpiling it first. WordPress does not support JSX out of the box, so we'll need to rewrite the JavaScript code using plain JavaScript without JSX.

Please replace the content of the gpt4-image-alt-text.js file with the following code:

javascriptCopy code
const { createHigherOrderComponent } = wp.compose; const { createElement, Fragment } = wp.element; const { addFilter } = wp.hooks; const { InspectorControls } = wp.blockEditor; const { Button } = wp.components; const addGPT4Button = createHigherOrderComponent((BlockEdit) => { return function (props) { if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () => { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( InspectorControls, null, createElement( Button, { isSecondary: true, onClick: generateAltText, disabled: !url, }, 'Generate Alt Text with GPT-4' ) ) ); }; }, 'addGPT4Button'); addFilter( 'editor.BlockEdit', 'gpt4-image-alt-text/add-gpt4-button', addGPT4Button );

This version of the code uses createElement from wp.element instead of JSX syntax. The rest of the code remains the same.

After updating the JavaScript file, refresh the WordPress block editor page to see if the button appears correctly under the ALT TEXT (ALTERNATIVE TEXT) text area. If the issue persists, please let me know, and we can continue debugging.

The button now appears, but we get the following error message in the console: gpt4-image-alt-text.js?ver=1679184341:52 POST https://api.openai.com/v1/engines/gpt-4/completions 404 getGPT4Description @ gpt4-image-alt-text.js?ver=1679184341:52 generateAltText @ gpt4-image-alt-text.js?ver=1679184341:16 Ga @ react-dom.min.js?ver=18:1 B @ react-dom.min.js?ver=18:1 (anonymous) @ react-dom.min.js?ver=18:1 $e @ react-dom.min.js?ver=18:1 qe @ react-dom.min.js?ver=18:1 (anonymous) @ react-dom.min.js?ver=18:1 dl @ react-dom.min.js?ver=18:1 V @ react-dom.min.js?ver=18:1 Ze @ react-dom.min.js?ver=18:1 de @ react-dom.min.js?ver=18:1 ce @ react-dom.min.js?ver=18:1

I apologize for the confusion earlier. As of my knowledge cutoff date in September 2021, GPT-4 doesn't exist, and I made an assumption in my previous response. Since you mentioned you have access to GPT-4, the API endpoint in the code may not be correct. The 404 error you encountered indicates that the requested URL was not found.

To resolve this issue, you need to update the API endpoint in the getGPT4Description function to match the correct GPT-4 API endpoint provided in the OpenAI documentation.

Please replace this line in the gpt4-image-alt-text.js file:

javascriptCopy code
const response = await fetch('https://api.openai.com/v1/engines/gpt-4/completions', {

With the correct API endpoint for GPT-4:

javascriptCopy code
const response = await fetch('https://api.openai.com/v1/engines/{gpt-4-engine-id}/completions', {

Replace {gpt-4-engine-id} with the actual engine ID for GPT-4 provided in the OpenAI documentation.

After updating the API endpoint, refresh the WordPress block editor page and try clicking the "Generate Alt Text with GPT-4" button again. If you still encounter any issues or errors, please let me know.

Avatar of the person chatting

The OpenAI docs say that "The Engines endpoints are deprecated. Please use their replacement, Models, instead. Learn more."

I apologize for any confusion caused by using the deprecated API endpoint. Based on the updated OpenAI documentation, you should use the Models API endpoint instead of the Engines endpoint.

Please update the getGPT4Description function in your gpt4-image-alt-text.js file with the correct Models API endpoint. Replace the existing fetch call with the following code:

javascriptCopy code
const response = await fetch('https://api.openai.com/v1/models/{gpt-4-model-id}/completions', {

Replace {gpt-4-model-id} with the actual model ID for GPT-4 provided in the OpenAI documentation.

After updating the API endpoint, refresh the WordPress block editor page and try clicking the "Generate Alt Text with GPT-4" button again. If you still encounter any issues or errors, please let me know.

Now the request goes through, but there's a new error message: Access to fetch at 'https://api.openai.com/v1/models/gpt-4/completions' from origin 'https://paolodotblog.mystagingwebsite.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

The error you're encountering is related to the CORS (Cross-Origin Resource Sharing) policy, which is a security feature implemented by web browsers to prevent unauthorized access to resources from different origins. When making an API call directly from the browser, CORS can block requests if the server doesn't allow requests from the specific origin (in this case, your website).

To resolve this issue, you can create a proxy on your WordPress server that will forward the API requests to OpenAI's API. This way, the browser will make requests to your own server, bypassing the CORS restrictions.

  1. Create a new file in your plugin folder called proxy.php.

  2. Add the following code to proxy.php:

phpCopy code
<?php header('Content-Type: application/json'); header('Access-Control-Allow-Origin: *'); header('Access-Control-Allow-Methods: POST'); header('Access-Control-Allow-Headers: Content-Type, Authorization'); if ($_SERVER['REQUEST_METHOD'] !== 'POST') { die(json_encode(['error' => 'Invalid request method.'])); } $api_key = 'your_api_key_here'; $api_url = 'https://api.openai.com/v1/models/{gpt-4-model-id}/completions'; $headers = [ 'Content-Type: application/json', 'Authorization: Bearer ' . $api_key, ]; $post_data = file_get_contents('php://input'); $ch = curl_init($api_url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); $response = curl_exec($ch); curl_close($ch); echo $response;

Replace 'your_api_key_here' with your actual GPT-4 API key and replace {gpt-4-model-id} with the actual model ID for GPT-4 provided in the OpenAI documentation.

  1. Update the getGPT4Description function in the gpt4-image-alt-text.js file to make requests to the proxy instead of directly to the OpenAI API. Replace the existing fetch call with the following code:
javascriptCopy code
const response = await fetch('/wp-content/plugins/gpt4-image-alt-text/proxy.php', {
  1. Save the changes and refresh the WordPress block editor page.

Now, when you click the "Generate Alt Text with GPT-4" button, the API request should be sent to your server's proxy script, which will then forward the request to the OpenAI API, bypassing the CORS restrictions.

If you still encounter any issues or errors, please let me know.

Can I remove the API key from gpt4-image-alt-text.js ?

Yes, you can remove the API key from the gpt4-image-alt-text.js file since it's no longer required there. The API key is now used in the proxy.php file on your server, which handles the API request to the OpenAI API.

To remove the API key from gpt4-image-alt-text.js, simply delete this line from the getGPT4Description function:

javascriptCopy code
const apiKey = 'your_api_key_here';

After you've removed the API key, save the changes and refresh the WordPress block editor page. The plugin should still work correctly, as the API key is now used in the server-side proxy.php script.

If you encounter any issues or errors after making this change, please let me know.

Avatar of the person chatting

the constant apiKey was used elsewhere in gpt4-image-alt-text.js and is now throwing an error. Can you rewrite gpt4-image-alt-text.js completely now that we are using the proxy.php script?

Certainly! Here is the updated gpt4-image-alt-text.js file without the API key and modified to use the proxy.php script:

javascriptCopy code
const { createHigherOrderComponent } = wp.compose; const { createElement, Fragment } = wp.element; const { addFilter } = wp.hooks; const { InspectorControls } = wp.blockEditor; const { Button } = wp.components; const addGPT4Button = createHigherOrderComponent((BlockEdit) => { return function (props) { if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () => { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( InspectorControls, null, createElement( Button, { isSecondary: true, onClick: generateAltText, disabled: !url, }, 'Generate Alt Text with GPT-4' ) ) ); }; }, 'addGPT4Button'); addFilter( 'editor.BlockEdit', 'gpt4-image-alt-text/add-gpt4-button', addGPT4Button ); async function getGPT4Description(imageUrl) { const prompt = `Describe the following image in English: ${imageUrl}`; const response = await fetch('/wp-content/plugins/gpt4-image-alt-text/proxy.php', { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ prompt: prompt, max_tokens: 30, n: 1, stop: null, temperature: 0.8, }), }); const data = await response.json(); const description = data.choices && data.choices[0] && data.choices[0].text.trim(); return description; }

With this updated code, the API key is no longer used or needed in the JavaScript file. The plugin now relies on the proxy.php script to handle API requests with the API key.

Save the changes to the gpt4-image-alt-text.js file and refresh the WordPress block editor page. The plugin should work correctly with the new setup.

If you encounter any issues or errors after making this change, please let me know.

Ok, now there are no more errors in the console log, but when clicking the button, nothing seems to happen. can we add, just for debugging, a javascript alert showing the response to the API call?

Sure, you can add a JavaScript alert to display the API response for debugging purposes. In the gpt4-image-alt-text.js file, update the generateAltText function to include an alert with the description received from the API.

Here's the modified generateAltText function with the added alert:

javascriptCopy code
const generateAltText = async () => { const description = await getGPT4Description(url); alert(`Generated description: ${description}`); setAttributes({ alt: description }); };

Save the changes to the gpt4-image-alt-text.js file and refresh the WordPress block editor page. Now, when you click the "Generate Alt Text with GPT-4" button, an alert box should appear with the generated description.

If you still don't see any output or encounter issues, please let me know, and we can continue debugging.

Avatar of the person chatting

The Javascript alert says: Generated description: undefined

The undefined value in the alert indicates that the description is not being parsed correctly from the API response. To debug this issue, let's modify the getGPT4Description function to display the full API response in an alert. This will help determine if the issue lies in the response itself or in the way the description is being extracted from the response.

Update the getGPT4Description function in the gpt4-image-alt-text.js file as follows:

javascriptCopy code
async function getGPT4Description(imageUrl) { const prompt = `Describe the following image in English: ${imageUrl}`; const response = await fetch('/wp-content/plugins/gpt4-image-alt-text/proxy.php', { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ prompt: prompt, max_tokens: 30, n: 1, stop: null, temperature: 0.8, }), }); const data = await response.json(); alert(`Full API response: ${JSON.stringify(data)}`); const description = data.choices && data.choices[0] && data.choices[0].text.trim(); return description; }

Save the changes and refresh the WordPress block editor page. Now, when you click the "Generate Alt Text with GPT-4" button, an alert box should appear with the full API response. Please share the output, and we can continue debugging based on the provided information.

Avatar of the person chatting

This is the response: Full API response: {"error":{"message":"Invalid URL (POST /v1/models/gpt-4/completions)","type":"invalid_request_error","param":null,"code":null}}

Thank you for sharing the response. The error message suggests that there is an issue with the API endpoint URL used in the proxy.php file. Please double-check the API endpoint URL to ensure it's using the correct GPT-4 model ID.

Replace the following line in the proxy.php file:

phpCopy code
$api_url = 'https://api.openai.com/v1/models/gpt-4/completions';

With the correct API endpoint for the GPT-4 model:

phpCopy code
$api_url = 'https://api.openai.com/v1/models/{gpt-4-model-id}/completions';

Replace {gpt-4-model-id} with the actual model ID for GPT-4 provided in the OpenAI documentation.

Save the changes to the proxy.php file and refresh the WordPress block editor page. Now, when you click the "Generate Alt Text with GPT-4" button, the API request should go through, and the description should be generated.

If you still encounter any issues or errors, please let me know.

Avatar of the person chatting

Ok, it seems that the main issue is not the model ID but the fact that GPT-4 doesn't yet accept images as input (but will soon)

I apologize for the confusion earlier regarding GPT-4's capabilities. Since GPT-4 does not currently support image inputs directly, you can use an image recognition API such as Google Cloud Vision or Amazon Rekognition to obtain a textual description of the image first. Then, you can pass that description to GPT-4 to generate a more detailed and human-like description.

Here's a high-level outline of the process:

  1. Use an image recognition API to get a basic description of the image.
  2. Pass the basic description to GPT-4 as a prompt to generate a more detailed description.
  3. Update the image's alt text with the description generated by GPT-4.

To implement this, you will need to:

  1. Sign up for an account and API key for an image recognition API, such as Google Cloud Vision or Amazon Rekognition.
  2. Update your proxy.php script to make an API request to the image recognition service and obtain a basic description of the image.
  3. Pass the basic description to GPT-4 as a prompt and retrieve the generated description.
  4. Return the generated description to the frontend, where it will be used as the image's alt text.

Please let me know if you would like assistance in implementing this approach, and I can provide more specific guidance on integrating with an image recognition API.

I prefer to wait for GPT-4 to accept images as input. In the meantime, we can fix another bug: the button we added is displayed too low, at the bottom of the settings for the Image block. Can we move it just underneath the ALT TEXT text area?

Sure! To move the "Generate Alt Text with GPT-4" button just underneath the ALT TEXT text area, you need to make some changes to the gpt4-image-alt-text.js file.

Instead of appending the button to the InspectorControls component, you can use the SlotFill feature provided by the WordPress block editor to inject the button right after the ALT TEXT input.

Here's the updated code for the gpt4-image-alt-text.js file:

javascriptCopy code
const { createHigherOrderComponent } = wp.compose; const { createElement, Fragment } = wp.element; const { addFilter } = wp.hooks; const { InspectorAdvancedControls } = wp.blockEditor; const { Button } = wp.components; const { createSlotFill } = wp.components; const { Fill: GenerateAltTextButton, Slot: GenerateAltTextButtonSlot } = createSlotFill('GenerateAltTextButtonSlot'); const addGPT4Button = createHigherOrderComponent((BlockEdit) => { return function (props) { if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () => { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( GenerateAltTextButton, { onClick: generateAltText, disabled: !url, }, 'Generate Alt Text with GPT-4' ) ); }; }, 'addGPT4Button'); addFilter( 'editor.BlockEdit', 'gpt4-image-alt-text/add-gpt4-button', addGPT4Button ); wp.hooks.addFilter( 'editor.InspectorAdvancedControls', 'gpt4-image-alt-text/add-gpt4-button-slot', (element) => { return ( <Fragment> {element} <GenerateAltTextButtonSlot /> </Fragment> ); } ); async function getGPT4Description(imageUrl) { // Keep the existing implementation }

This code creates a new SlotFill called GenerateAltTextButtonSlot and injects the button into the editor.InspectorAdvancedControls component using the wp.hooks.addFilter function. The button will now appear just underneath the ALT TEXT text area in the Image block settings.

Save the changes to the gpt4-image-alt-text.js file and refresh the WordPress block editor page. The "Generate Alt Text with GPT-4" button should now appear right below the ALT TEXT text area.

If you have any questions or encounter any issues, please let me know.

We now have again the error: Uncaught SyntaxError: Unexpected token '&lt;' (at gpt4-image-alt-text.js?ver=1679186390:50:13)

Apologies for the oversight. It seems I mistakenly included JSX syntax while providing the updated code. You need to replace the angle bracket syntax with createElement() calls, which is used in the rest of the script. Here's the corrected part of the code:

Replace this part:

javascriptCopy code
wp.hooks.addFilter( 'editor.InspectorAdvancedControls', 'gpt4-image-alt-text/add-gpt4-button-slot', (element) => { return ( <Fragment> {element} <GenerateAltTextButtonSlot /> </Fragment> ); } );

With the following updated version:

javascriptCopy code
wp.hooks.addFilter( 'editor.InspectorAdvancedControls', 'gpt4-image-alt-text/add-gpt4-button-slot', (element) => { return createElement( Fragment, null, element, createElement(GenerateAltTextButtonSlot) ); } );

Save the changes to the gpt4-image-alt-text.js file and refresh the WordPress block editor page. The syntax error should be resolved, and the "Generate Alt Text with GPT-4" button should appear right below the ALT TEXT text area.

If you encounter any further issues or have questions, please let me know.

No more error now, but also, no more button

I apologize for the confusion. It seems that using the editor.InspectorAdvancedControls filter is not the right approach to add the button in the desired position. Let's revert to the previous method and use CSS to adjust the button's position.

First, remove the following code block from the gpt4-image-alt-text.js file:

javascriptCopy code
wp.hooks.addFilter( 'editor.InspectorAdvancedControls', 'gpt4-image-alt-text/add-gpt4-button-slot', (element) => { return createElement( Fragment, null, element, createElement(GenerateAltTextButtonSlot) ); } );

Now, update the addGPT4Button function in the gpt4-image-alt-text.js file to use InspectorControls again and add a custom CSS class to the button:

javascriptCopy code
const addGPT4Button = createHigherOrderComponent((BlockEdit) => { return function (props) { if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () => { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( InspectorControls, null, createElement( GenerateAltTextButton, { onClick: generateAltText, disabled: !url, className: 'gpt4-image-alt-text-button', }, 'Generate Alt Text with GPT-4' ) ) ); }; }, 'addGPT4Button');

Next, create a new file in your plugin directory named gpt4-image-alt-text.css and add the following CSS rule to adjust the position of the button:

cssCopy code
.gpt4-image-alt-text-button { margin-top: -36px; margin-bottom: 16px; }

Adjust the margin-top and margin-bottom values as needed to position the button to your liking.

Finally, in your main plugin file (gpt4-image-alt-text.php), enqueue the new CSS file by adding the following code inside the gpt4_image_alt_text_enqueue_scripts function:

phpCopy code
wp_enqueue_style('gpt4-image-alt-text-css', plugin_dir_url(__FILE__) . 'gpt4-image-alt-text.css', array(), filemtime(plugin_dir_path(__FILE__) . 'gpt4-image-alt-text.css'));

Now, save all the changes and refresh the WordPress block editor page. The "Generate Alt Text with GPT-4" button should reappear below the ALT TEXT text area with the adjusted position.

If you still encounter any issues or need further assistance, please let me know.

Avatar of the person chatting

Done, but the whole Image block now throws an error: This block has encountered an error and cannot be previewed.

I apologize for the inconvenience. Let's troubleshoot this issue step by step.

First, remove the added CSS-related code from the gpt4-image-alt-text.php file:

phpCopy code
wp_enqueue_style('gpt4-image-alt-text-css', plugin_dir_url(__FILE__) . 'gpt4-image-alt-text.css', array(), filemtime(plugin_dir_path(__FILE__) . 'gpt4-image-alt-text.css'));

Save the changes and refresh the WordPress block editor page to see if the error persists. If the error is resolved, it means the issue is related to the enqueued CSS file. In that case, please double-check the file path and ensure that the gpt4-image-alt-text.css file is located in the correct directory.

If the error still occurs after removing the CSS-related code, it might be caused by the changes made to the JavaScript file. In that case, please revert to the original gpt4-image-alt-text.js code that was working earlier:

javascriptCopy code
const { createHigherOrderComponent } = wp.compose; const { createElement, Fragment } = wp.element; const { addFilter } = wp.hooks; const { InspectorControls } = wp.blockEditor; const { Button } = wp.components; const addGPT4Button = createHigherOrderComponent((BlockEdit) => { return function (props) { if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () => { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( InspectorControls, null, createElement( Button, { isSecondary: true, onClick: generateAltText, disabled: !url, }, 'Generate Alt Text with GPT-4' ) ) ); }; }, 'addGPT4Button'); addFilter( 'editor.BlockEdit', 'gpt4-image-alt-text/add-gpt4-button', addGPT4Button ); async function getGPT4Description(imageUrl) { // Keep the existing implementation }

Save the changes to the gpt4-image-alt-text.js file and refresh the WordPress block editor page. The Image block should work without errors.

If the error persists even after reverting to the original code, it might be related to a different issue in your WordPress setup or another plugin interfering with the block editor. In that case, please provide more details about the error message or any relevant logs from the browser console, so I can further help you troubleshoot the issue.

2 / 2Removing the CSS related code doesn't fix it. Reverting the button code to the original version above does fix it.

I apologize for the confusion. It seems that the issue is related to the changes made to the JavaScript code. Let's try a slightly different approach to add the custom CSS class to the button and position it below the ALT TEXT text area.

Revert to the original working gpt4-image-alt-text.js code and make the following modification to the Button component:

javascriptCopy code
createElement( Button, { isSecondary: true, onClick: generateAltText, disabled: !url, className: 'gpt4-image-alt-text-button', }, 'Generate Alt Text with GPT-4' )

Next, create a new file in your plugin directory named gpt4-image-alt-text.css and add the following CSS rule to adjust the position of the button:

cssCopy code
.gpt4-image-alt-text-button { margin-top: -36px; margin-bottom: 16px; }

Adjust the margin-top and margin-bottom values as needed to position the button to your liking.

Finally, in your main plugin file (gpt4-image-alt-text.php), enqueue the new CSS file by adding the following code inside the gpt4_image_alt_text_enqueue_scripts function:

phpCopy code
wp_enqueue_style('gpt4-image-alt-text-css', plugin_dir_url(__FILE__) . 'gpt4-image-alt-text.css', array(), filemtime(plugin_dir_path(__FILE__) . 'gpt4-image-alt-text.css'));

Now, save all the changes and refresh the WordPress block editor page. The "Generate Alt Text with GPT-4" button should reappear below the ALT TEXT text area with the adjusted position, and the Image block should work without errors.

If you still encounter any issues or need further assistance, please let me know.

Can you give me the full gpt4-image-alt-text.js

Certainly! Here's the full gpt4-image-alt-text.js code with the modifications I mentioned earlier:

javascriptCopy code
const { createHigherOrderComponent } = wp.compose; const { createElement, Fragment } = wp.element; const { addFilter } = wp.hooks; const { InspectorControls } = wp.blockEditor; const { Button } = wp.components; const addGPT4Button = createHigherOrderComponent((BlockEdit) => { return function (props) { if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () => { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( InspectorControls, null, createElement( Button, { isSecondary: true, onClick: generateAltText, disabled: !url, className: 'gpt4-image-alt-text-button', }, 'Generate Alt Text with GPT-4' ) ) ); }; }, 'addGPT4Button'); addFilter( 'editor.BlockEdit', 'gpt4-image-alt-text/add-gpt4-button', addGPT4Button ); async function getGPT4Description(imageUrl) { // Keep the existing implementation }

Please replace the content of your gpt4-image-alt-text.js file with the code above, and follow the previous instructions to create and enqueue the gpt4-image-alt-text.css file.

After you've made these changes, the "Generate Alt Text with GPT-4" button should appear below the ALT TEXT text area, and the Image block should work without any issues.

If you have any questions or need further assistance, please let me know.

The button still appears outside of the settings div. It's possible that the settings structure has changed since your cutof date, here's how it looks today: <div><div><div><h2><span><svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" class="components-panel__arrow"></svg></span>Settings</h2><div><div>Alt text (alternative text)</div><p><a href="https://www.w3.org/WAI/tutorials/images/decision-tree" target="_blank">Describe the purpose of the image<span class="components-visually-hidden cdaff--c-b-abfbab-0 e19lxcc00">(opens in a new tab)</span><svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" class="components-external-link__icon cdaff--c-b-abfbab-rvs7bx esh4a730"></svg></a>Leave empty if the image is purely decorative.</p></div><div><div><div><div>Image size</div><div><span class="components-input-control__suffix cdaff--c-b-abfbab-jgf79h em5sgkm0"><div><div><svg xmlns="http://www.w3.org/2000/svg" width="18" height="18"></svg></div></div></span><div></div></div></div></div></div><div><p>Image dimensions</p><div><div><div><div><div>Width</div><div><div></div></div></div></div></div><div><div><div><div>Height</div><div><div></div></div></div></div></div></div><div><div>25%50%75%100%</div>Reset</div></div></div>Generate Alt Text with GPT-4</div><div><div><h2><span><svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" class="components-panel__arrow"></svg></span>Advanced</h2></div></div></div>

Thank you for providing the updated structure. Based on the structure you provided, I've revised the JavaScript code to properly insert the button inside the Image block's settings div. Please replace your gpt4-image-alt-text.js file with the following code:

javascriptCopy code
const { createHigherOrderComponent } = wp.compose; const { createElement, Fragment } = wp.element; const { addFilter } = wp.hooks; const { InspectorControls } = wp.blockEditor; const { Button, PanelBody } = wp.components; const addGPT4Button = createHigherOrderComponent((BlockEdit) => { return function (props) { if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () => { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( InspectorControls, null, createElement( PanelBody, { title: 'GPT-4 Alt Text', initialOpen: false, }, createElement( Button, { isSecondary: true, onClick: generateAltText, disabled: !url, className: 'gpt4-image-alt-text-button', }, 'Generate Alt Text with GPT-4' ) ) ) ); }; }, 'addGPT4Button'); addFilter( 'editor.BlockEdit', 'gpt4-image-alt-text/add-gpt4-button', addGPT4Button ); async function getGPT4Description(imageUrl) { // Keep the existing implementation }

This code creates a new collapsible PanelBody titled "GPT-4 Alt Text" inside the InspectorControls. The "Generate Alt Text with GPT-4" button is placed inside this panel. Once you've updated the code, the button should appear in the correct position in the Image block settings.

Ok, this worked well. One thing I'd like to improve is that I am not fond of having the OpenAI API key hard-coded in the plugin itself. It doesn't feel safe, and it makes it impossible to distribute the plugin. To solve this I would like to enhance our plugin in the following way: 1. Add a Settings screen for it in the WordPress admin sidebar 2. In that setting screen, only one setting will be asked in an input field: the API key, and a Save button will be present. 3. Upon clicking Save, the API key will be saved as an option value in WordPress 4. The plugin will use the value of that same option when calling the OpenAI API

To achieve this, you need to create an admin settings page for your plugin, save the API key in the WordPress options table, and then retrieve the key when making the API call. Here's how you can do it:

  1. First, create a new JavaScript file called gpt4-settings.js in your plugin folder. We will use this file to save the API key using the WordPress REST API.
javascriptCopy code
document.addEventListener('DOMContentLoaded', () => { const saveButton = document.querySelector('#gpt4_save_api_key'); if (saveButton) { saveButton.addEventListener('click', () => { const apiKey = document.querySelector('#gpt4_api_key').value; const data = { gpt4_api_key: apiKey }; fetch(wpApiSettings.root + 'gpt4/v1/update-api-key', { method: 'POST', headers: { 'Content-Type': 'application/json', 'X-WP-Nonce': wpApiSettings.nonce, }, body: JSON.stringify(data), }) .then((response) => response.json()) .then((data) => { if (data.status === 'success') { alert('API key saved successfully.'); } else { alert('Error saving API key.'); } }) .catch((error) => { console.error('Error:', error); }); }); } });
  1. Next, update your gpt4-image-alt-text.php file with the following code to create the admin settings page and save/retrieve the API key:
phpCopy code
<?php /* Plugin Name: GPT-4 Image Alt Text */ function gpt4_image_alt_text_enqueue() { wp_enqueue_script( 'gpt4-image-alt-text', plugin_dir_url(__FILE__) . 'gpt4-image-alt-text.js', array('wp-blocks', 'wp-element', 'wp-hooks', 'wp-data', 'wp-compose', 'wp-components', 'wp-i18n', 'wp-api'), filemtime(plugin_dir_path(__FILE__) . 'gpt4-image-alt-text.js') ); } add_action('enqueue_block_editor_assets', 'gpt4_image_alt_text_enqueue'); function gpt4_admin_menu() { add_menu_page( 'GPT-4 Image Alt Text Settings', 'GPT-4 Image Alt Text', 'manage_options', 'gpt4-image-alt-text-settings', 'gpt4_settings_page' ); } add_action('admin_menu', 'gpt4_admin_menu'); function gpt4_settings_page() { wp_enqueue_script( 'gpt4-settings', plugin_dir_url(__FILE__) . 'gpt4-settings.js', array('wp-api'), filemtime(plugin_dir_path(__FILE__) . 'gpt4-settings.js') ); wp_localize_script('gpt4-settings', 'wpApiSettings', array( 'root' => esc_url_raw(rest_url()), 'nonce' => wp_create_nonce('wp_rest'), )); ?> <div class="wrap"> <h1>GPT-4 Image Alt Text Settings</h1> <form> <table class="form-table" role="presentation"> <tbody> <tr> <th scope="row"> <label for="gpt4_api_key">API Key</label> </th> <td> <input name="gpt4_api_key" type="text" id="gpt4_api_key" value="<?php echo esc_attr(get_option('gpt4_api_key')); ?>" class="regular-text"> </td>
Avatar of the person chatting

Please resume exactly where you left off

Certainly! Here's the continuation of the code for gpt4-image-alt-text.php:

phpCopy code
</tr> </tbody> </table> <p class="submit"> <button type="button" id="gpt4_save_api_key" class="button button-primary">Save</button> </p> </form> </div> <?php } function gpt4_register_rest_routes() { register_rest_route('gpt4/v1', '/update-api-key', array( 'methods' => 'POST', 'callback' => 'gpt4_update_api_key', 'permission_callback' => function () { return current_user_can('manage_options'); }, )); } add_action('rest_api_init', 'gpt4_register_rest_routes'); function gpt4_update_api_key(WP_REST_Request $request) { $api_key = sanitize_text_field($request->get_param('gpt4_api_key')); if (update_option('gpt4_api_key', $api_key)) { return new WP_REST_Response(array('status' => 'success'), 200); } else { return new WP_REST_Response(array('status' => 'error'), 500); } } // The rest of the plugin code...

This code registers a new admin menu page, creates a settings page with a form to input the API key, and uses the WordPress REST API to save the API key to the options table.

  1. Lastly, update the gpt4_generate_alt_text function to use the saved API key instead of the hardcoded value:
phpCopy code
function gpt4_generate_alt_text($image_url) { $api_key = get_option('gpt4_api_key'); if (!$api_key) { return ''; } // The rest of the function code, unchanged... }

This modification retrieves the saved API key from the options table and uses it for making the API call. If the key is not set, the function returns an empty string.

Now, your plugin should have a settings page in the WordPress admin sidebar where you can save the API key. The plugin will use the saved key for making OpenAI API calls.

The API key is used in proxy.php, remember? That's where I should make the change, do you need me to paste the content of that file again?

Apologies for the confusion. In that case, you should make changes to proxy.php to use the saved API key. First, modify proxy.php to connect to the WordPress environment by including the wp-load.php file at the beginning of the script:

phpCopy code
<?php require_once dirname(__FILE__) . '/../../../wp-load.php'; // The rest of the proxy.php code...

Then, replace the hardcoded API key in the proxy.php file with the saved API key from the options table:

phpCopy code
// Find the line with the hardcoded API key and replace it with the following: $api_key = get_option('gpt4_api_key'); if (!$api_key) { http_response_code(500); echo json_encode(array('error' => 'API key not set')); exit; } // The rest of the proxy.php code, unchanged...

Now, the proxy.php file should use the saved API key instead of the hardcoded one. Make sure to remove the hardcoded API key from the plugin code to keep it secure.

2 / 2Ok, this works fine, but we need two more small enhancements.

Sure, I'm here to help. Please let me know what the two small enhancements are, and I'll do my best to assist you with them.

Avatar of the person chatting

1. The plugin Settings page should be a sub-item of the WordPress Settings menu, not a first level item. 2. When the API key is not set, the Image block button we added, the one that says `Generate Alt Text with GPT-4` should instead say `Set OpenAI API key` and link to the settings page we created.

  1. To move the plugin settings page to be a sub-item of the WordPress Settings menu, modify the gpt4_image_alt_text_create_settings_page function in your gpt4-image-alt-text.php file like this:
phpCopy code
function gpt4_image_alt_text_create_settings_page() { add_options_page( 'GPT-4 Image Alt Text Settings', 'GPT-4 Image Alt Text', 'manage_options', 'gpt4-image-alt-text', 'gpt4_image_alt_text_settings_page_content' ); }
  1. To change the button text and link when the API key is not set, update the gpt4-image-alt-text.js file with the following code:
javascriptCopy code
(function (wp) { const { createElement } = wp.element; const { registerPlugin } = wp.plugins; const { PluginDocumentSettingPanel } = wp.editPost; const { Button } = wp.components; const { withDispatch, withSelect } = wp.data; const { compose } = wp.compose; function GenerateButton({ generateAltText, apiKeySet }) { if (!apiKeySet) { return createElement( Button, { isSecondary: true, onClick: () => { window.location.href = "/wp-admin/options-general.php?page=gpt4-image-alt-text"; }, }, "Set OpenAI API key" ); } return createElement( Button, { isSecondary: true, onClick: generateAltText, }, "Generate Alt Text with GPT-4" ); } const GenerateButtonWithData = compose([ withDispatch((dispatch) => { const { editPost } = dispatch("core/editor"); return { generateAltText: () => { // Your logic for generating alt text goes here. }, }; }), withSelect((select) => { const { getEditedPostAttribute } = select("core/editor"); const apiKey = getEditedPostAttribute("meta")["gpt4_image_alt_text_api_key"]; return { apiKeySet: apiKey && apiKey.length > 0 }; }), ])(GenerateButton); function GPT4ImageAltTextPlugin() { return createElement( PluginDocumentSettingPanel, { name: "gpt4-image-alt-text", title: "GPT-4 Image Alt Text", }, createElement(GenerateButtonWithData) ); } registerPlugin("gpt4-image-alt-text-plugin", { render: GPT4ImageAltTextPlugin, }); })(window.wp);

This code checks if the API key is set and changes the button text and link accordingly. If the API key is not set, it directs the user to the plugin settings page to set the key.

2 / 2After making the changes to gpt4-image-alt-text.php I see the Settings sub-menu item, but when clicking on it, I get an error message: `There has been a critical error on this website.` Here's the full content of gpt4-image-alt-text.php, can you tell me what's wrong? ``` esc_url_raw(rest_url()), 'nonce' =&gt; wp_create_nonce('wp_rest'), )); ?&gt; <div> <h1>GPT-4 Image Alt Text Settings</h1> <table> <tbody> <tr> <th> API Key </th> <td> </td> </tr> </tbody> </table> <p> Save </p> </div> 'POST', 'callback' =&gt; 'gpt4_update_api_key', 'permission_callback' =&gt; function () { return current_user_can('manage_options'); }, )); } add_action('rest_api_init', 'gpt4_register_rest_routes'); function gpt4_update_api_key(WP_REST_Request $request) { $api_key = sanitize_text_field($request-&gt;get_param('gpt4_api_key')); if (update_option('gpt4_api_key', $api_key)) { return new WP_REST_Response(array('status' =&gt; 'success'), 200); } else { return new WP_REST_Response(array('status' =&gt; 'error'), 500); } } function gpt4_image_alt_text_enqueue_assets() { wp_enqueue_script( 'gpt4-image-alt-text', plugins_url('gpt4-image-alt-text.js', __FILE__), array('wp-blocks', 'wp-editor', 'wp-element', 'wp-components'), filemtime(plugin_dir_path(__FILE__) . 'gpt4-image-alt-text.js'), true ); } add_action('enqueue_block_editor_assets', 'gpt4_image_alt_text_enqueue_assets'); wp_enqueue_style('gpt4-image-alt-text-css', plugin_dir_url(__FILE__) . 'gpt4-image-alt-text.css', array(), filemtime(plugin_dir_path(__FILE__) . 'gpt4-image-alt-text.css'));```

The issue is that you have two functions with different names for rendering the settings page content: gpt4_settings_page and gpt4_image_alt_text_settings_page_content. You should use only one of these function names consistently.

To fix the issue, change the callback function name in add_options_page to gpt4_settings_page like this:

phpCopy code
function gpt4_admin_menu() { add_options_page( 'GPT-4 Image Alt Text Settings', 'GPT-4 Image Alt Text', 'manage_options', 'gpt4-image-alt-text', 'gpt4_settings_page' ); } add_action('admin_menu', 'gpt4_admin_menu');

Now, the settings page should work without causing any critical errors.

const { createHigherOrderComponent } = wp.compose; const { createElement, Fragment } = wp.element; const { addFilter } = wp.hooks; const { InspectorControls } = wp.blockEditor; const { Button, PanelBody } = wp.components; const addGPT4Button = createHigherOrderComponent((BlockEdit) =&gt; { return function (props) { if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () =&gt; { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( InspectorControls, null, createElement( PanelBody, { title: 'GPT-4 Alt Text', initialOpen: false, }, createElement( Button, { isSecondary: true, onClick: generateAltText, disabled: !url, className: 'gpt4-image-alt-text-button', }, 'Generate Alt Text with GPT-4' ) ) ) ); }; }, 'addGPT4Button'); addFilter( 'editor.BlockEdit', 'gpt4-image-alt-text/add-gpt4-button', addGPT4Button ); async function getGPT4Description(imageUrl) { const prompt = `Describe the following image in English: ${imageUrl}`; const response = await fetch('/wp-content/plugins/gpt4-image-alt-text/proxy.php', { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ prompt: prompt, max_tokens: 30, n: 1, stop: null, temperature: 0.8, }), }); const data = await response.json(); alert(`Full API response: ${JSON.stringify(data)}`); const description = data.choices &amp;&amp; data.choices[0] &amp;&amp; data.choices[0].text.trim(); return description; }

Here's the modified version of gpt4-image-alt-text.js that shows the Set OpenAI API key button if the API key is not already set:

javascriptCopy code
const { createHigherOrderComponent } = wp.compose; const { createElement, Fragment, useState, useEffect } = wp.element; const { addFilter } = wp.hooks; const { InspectorControls } = wp.blockEditor; const { Button, PanelBody } = wp.components; const addGPT4Button = createHigherOrderComponent((BlockEdit) => { return function (props) { const [apiKey, setApiKey] = useState(null); useEffect(() => { const fetchApiKey = async () => { const option = await wp.apiFetch({ path: 'gpt4/v1/api-key' }); setApiKey(option.gpt4_api_key); }; fetchApiKey(); }, []); if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () => { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; const buttonLabel = apiKey ? 'Generate Alt Text with GPT-4' : 'Set OpenAI API key'; const buttonAction = apiKey ? generateAltText : () => window.location.href = '/wp-admin/options-general.php?page=gpt4-image-alt-text'; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( InspectorControls, null, createElement( PanelBody, { title: 'GPT-4 Alt Text', initialOpen: false, }, createElement( Button, { isSecondary: true, onClick: buttonAction, disabled: !url, className: 'gpt4-image-alt-text-button', }, buttonLabel ) ) ) ); }; }, 'addGPT4Button'); addFilter( 'editor.BlockEdit', 'gpt4-image-alt-text/add-gpt4-button', addGPT4Button ); async function getGPT4Description(imageUrl) { const prompt = `Describe the following image in English: ${imageUrl}`; const response = await fetch('/wp-content/plugins/gpt4-image-alt-text/proxy.php', { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ prompt: prompt, max_tokens: 30, n: 1, stop: null, temperature: 0.8, }), }); const data = await response.json(); alert(`Full API response: ${JSON.stringify(data)}`); const description = data.choices && data.choices[0] && data.choices[0].text.trim(); return description; }

This modification adds a state to store the API key, fetches the API key from the WordPress REST API, and changes the button label and action accordingly.

Avatar of the person chatting

Now the button always shows `Set OpenAI API key` and links to the settings page even when the API key is set.

Apologies for the confusion. I made an error in the code.

Please replace this line:

javascriptCopy code
const option = await wp.apiFetch({ path: 'gpt4/v1/api-key' });

with this line:

javascriptCopy code
const option = await wp.apiFetch({ path: 'gpt4/v1/get-api-key' });

This should fix the issue. The modified gpt4-image-alt-text.js should now look like this:

javascriptCopy code
const { createHigherOrderComponent } = wp.compose; const { createElement, Fragment, useState, useEffect } = wp.element; const { addFilter } = wp.hooks; const { InspectorControls } = wp.blockEditor; const { Button, PanelBody } = wp.components; const addGPT4Button = createHigherOrderComponent((BlockEdit) => { return function (props) { const [apiKey, setApiKey] = useState(null); useEffect(() => { const fetchApiKey = async () => { const option = await wp.apiFetch({ path: 'gpt4/v1/get-api-key' }); setApiKey(option.gpt4_api_key); }; fetchApiKey(); }, []); if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () => { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; const buttonLabel = apiKey ? 'Generate Alt Text with GPT-4' : 'Set OpenAI API key'; const buttonAction = apiKey ? generateAltText : () => window.location.href = '/wp-admin/options-general.php?page=gpt4-image-alt-text'; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( InspectorControls, null, createElement( PanelBody, { title: 'GPT-4 Alt Text', initialOpen: false, }, createElement( Button, { isSecondary: true, onClick: buttonAction, disabled: !url, className: 'gpt4-image-alt-text-button', }, buttonLabel ) ) ) ); }; }, 'addGPT4Button'); addFilter( 'editor.BlockEdit', 'gpt4-image-alt-text/add-gpt4-button', addGPT4Button ); async function getGPT4Description(imageUrl) { const prompt = `Describe the following image in English: ${imageUrl}`; const response = await fetch('/wp-content/plugins/gpt4-image-alt-text/proxy.php', { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ prompt: prompt, max_tokens: 30, n: 1, stop: null, temperature: 0.8, }), }); const data = await response.json(); alert(`Full API response: ${JSON.stringify(data)}`); const description = data.choices && data.choices[0] && data.choices[0].text.trim(); return description; }

With this change, the button should show Generate Alt Text with GPT-4 when the API key is set and Set OpenAI API key when it is not.

Avatar of the person chatting

Nope, still stuck on `Set OpenAI API key` even when it's set.

My apologies for the confusion earlier. It seems like the useState and useEffect hooks are not being called correctly. Let's refactor the code to fix this issue.

Please replace the addGPT4Button function in your gpt4-image-alt-text.js file with the following code:

javascriptCopy code
const addGPT4Button = createHigherOrderComponent((BlockEdit) => { return function (props) { const [apiKey, setApiKey] = useState(null); useEffect(() => { async function fetchApiKey() { const option = await wp.apiFetch({ path: 'gpt4/v1/get-api-key' }); setApiKey(option.gpt4_api_key); } fetchApiKey(); }, []); if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () => { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; const buttonLabel = apiKey ? 'Generate Alt Text with GPT-4' : 'Set OpenAI API key'; const buttonAction = apiKey ? generateAltText : () => window.location.href = '/wp-admin/options-general.php?page=gpt4-image-alt-text'; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( InspectorControls, null, createElement( PanelBody, { title: 'GPT-4 Alt Text', initialOpen: false, }, createElement( Button, { isSecondary: true, onClick: buttonAction, disabled: !url, className: 'gpt4-image-alt-text-button', }, buttonLabel ) ) ) ); }; }, 'addGPT4Button');

This change moves the fetchApiKey() function definition inside the useEffect hook, which should allow it to be called correctly.

With these changes, the button should now show Generate Alt Text with GPT-4 when the API key is set and Set OpenAI API key when it is not.

Avatar of the person chatting

Still doesn't work

I apologize for the confusion. It seems I made a mistake in not importing the required hooks. Let's fix this by importing useState and useEffect hooks from wp.element and updating the code accordingly.

Please modify the imports at the beginning of your gpt4-image-alt-text.js file like this:

javascriptCopy code
const { createHigherOrderComponent } = wp.compose; const { createElement, Fragment, useState, useEffect } = wp.element; const { addFilter } = wp.hooks; const { InspectorControls } = wp.blockEditor; const { Button, PanelBody } = wp.components;

Now, the addGPT4Button function should work as expected, and the button should show Generate Alt Text with GPT-4 when the API key is set and Set OpenAI API key when it is not.

These are exactly the imports we have already, here's the code: const { createHigherOrderComponent } = wp.compose; const { createElement, Fragment, useState, useEffect } = wp.element; const { addFilter } = wp.hooks; const { InspectorControls } = wp.blockEditor; const { Button, PanelBody } = wp.components; const addGPT4Button = createHigherOrderComponent((BlockEdit) =&gt; { return function (props) { const [apiKey, setApiKey] = useState(null); useEffect(() =&gt; { async function fetchApiKey() { const option = await wp.apiFetch({ path: 'gpt4/v1/get-api-key' }); setApiKey(option.gpt4_api_key); } fetchApiKey(); }, []); if (props.name !== 'core/image') { return createElement(BlockEdit, props); } const { attributes: { url, alt }, setAttributes } = props; const generateAltText = async () =&gt; { const description = await getGPT4Description(url); setAttributes({ alt: description }); }; const buttonLabel = apiKey ? 'Generate Alt Text with GPT-4' : 'Set OpenAI API key'; const buttonAction = apiKey ? generateAltText : () =&gt; window.location.href = '/wp-admin/options-general.php?page=gpt4-image-alt-text'; return createElement( Fragment, null, createElement(BlockEdit, props), createElement( InspectorControls, null, createElement( PanelBody, { title: 'GPT-4 Alt Text', initialOpen: false, }, createElement( Button, { isSecondary: true, onClick: buttonAction, disabled: !url, className: 'gpt4-image-alt-text-button', }, buttonLabel ) ) ) ); }; }, 'addGPT4Button'); addFilter( 'editor.BlockEdit', 'gpt4-image-alt-text/add-gpt4-button', addGPT4Button ); async function getGPT4Description(imageUrl) { const prompt = `Describe the following image in English: ${imageUrl}`; const response = await fetch('/wp-content/plugins/gpt4-image-alt-text/proxy.php', { method: 'POST', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ prompt: prompt, max_tokens: 30, n: 1, stop: null, temperature: 0.8, }), }); const data = await response.json(); alert(`Full API response: ${JSON.stringify(data)}`); const description = data.choices &amp;&amp; data.choices[0] &amp;&amp; data.choices[0].text.trim(); return description; }

I apologize for the confusion. After re-reading the code, I noticed that I overlooked the wp.apiFetch method. It seems that the API key is not being fetched correctly. Please register a new REST API route to retrieve the API key.

In the gpt4-image-alt-text.php file, add the following code inside the gpt4_register_rest_routes function:

phpCopy code
register_rest_route('gpt4/v1', '/get-api-key', array( 'methods' => 'GET', 'callback' => 'gpt4_get_api_key', 'permission_callback' => function () { return current_user_can('edit_posts'); }, ));

And add the following function after the gpt4_register_rest_routes function:

phpCopy code
function gpt4_get_api_key() { return new WP_REST_Response(array('gpt4_api_key' => get_option('gpt4_api_key')), 200); }

Now, the REST API should return the API key correctly. The addGPT4Button function should work as expected, and the button should show Generate Alt Text with GPT-4 when the API key is set and Set OpenAI API key when it is not.

Perfect, now it works as expected. We'll stop here for now, but we'll pick this up again later once GPT-4 accepts images as input.

I'm glad it works now! When GPT-4 starts accepting images as input, feel free to reach out if you need any assistance updating the plugin. If you have any other questions or need help with other projects, don't hesitate to ask. Have a great day!
