Creating AI-powered content generation with ChatGPT-PHP in a custom WordPress plugin
If you’re a developer who’s looking to create AI-powered content generation within a custom WordPress plugin, then this article is for you. We’ll show you how to use the open source ChatGPT-PHP library to achieve this.
First, let’s briefly introduce ChatGPT-PHP. It’s a library that enables developers to create chatbots that can generate text. The text can be in response to user input, or it can be generated autonomously.
To use ChatGPT-PHP in a custom WordPress plugin, you’ll need to first install the library. The easiest way to do this is via Composer:
composer require chatgpt/chatgpt-php
Once you have the library installed, you can start using it to generate text. For example, let’s say you want to create a chatbot that can generate product descriptions.
First, you’ll need to create a file called product-descriptions.js in your plugin’s root directory. This file will contain the code for your chatbot.
Next, you’ll need to require the ChatGPT-PHP library in your product-descriptions.js file:
require(‘chatgpt-php’);
Now that you have the ChatGPT-PHP library required, you can start using it to generate text. For example, let’s say you want your chatbot to generate a product description for a hypothetical product called “Widget A”.
To do this, you’ll first need to create a file called widget-a.txt in your plugin’s root directory. This file will contain the template for your chatbot’s product description.
The template will consist of placeholder values that will be replaced with actual values when the chatbot generates the product description. For example, the template for the “Widget A” product might look like this:
{Product_Name}
The {Product_Name} is a {Product_Type} that {Product_Descriptive_Verb}. It is {Product_Adjective} and {Product_Adjective}.
As you can see, the template contains placeholder values for the product name, type, description, and adjectives.
Now that you have your template, you can use the ChatGPT-PHP library to generate the actual product description. To do this, you’ll need to add the following code to your product-descriptions.js file:
chatgpt.generateText(‘widget-a.txt’, {
productName: ‘Widget A’,
productType: ‘widget’,
productDescriptiveVerb: ‘does something’,
productAdjective: ‘amazing’,
productAdjective: ‘cool’
}, function(err, text) {
if (err) {
console.error(err);
} else {
console.log(text);
}
});
This code will generate the following product description:
Widget A
The Widget A is a widget that does something. It is amazing and cool.
In the previous article, we saw how to create a basic WordPress plugin that uses the ChatGPT PHP SDK to generate AI-powered content. In this article, we’ll extend the plugin to include a settings page, where we can configure the plugin to our needs.
First, we need to create a new file called “settings.php” in the plugin’s “admin” folder. This file will contain the HTML for the plugin’s settings page. We’ll start by adding a simple form that allows us to enter our ChatGPT API key:
| ChatGPT API Key | <input type="text" name="chatgpt_api_key" value="” /> |
|---|
Next, we need to register our setting with WordPress. We do this by adding the following code to the “register_settings” function in our “chatgpt.php” file:
register_setting( ‘chatgpt-settings-group’, ‘chatgpt_api_key’ );
Now that our setting is registered, we can access its value using the “get_option” function. We’ll use this to initialise the ChatGPT SDK in our “chatgpt.php” file:
$chatgpt = new ChatGPTSDK( get_option(‘chatgpt_api_key’) );
With the ChatGPT SDK initialised, we can now use it to generate AI-powered content in our WordPress plugin.
In the next article, we’ll see how to use the ChatGPT SDK to generate a list of recommended articles for a given topic.
If you want to get your hands on the source code for this project, you can find it on GitHub.
In this post, we’ll be continuing our series on creating AI-powered content generation with ChatGPT PHP in a custom WordPress plugin. In the previous post, we looked at how to get started with ChatGPT PHP and create a basic chatbot. In this post, we’ll be expanding on that and looking at how to use ChatGPT PHP to generate content.
We’ll be using the same chatbot example from the previous post, but this time we’ll be training it to generate content. The content will be in the form of questions and answers, and we’ll be using a dataset of FAQs to train the chatbot.
To start with, we need to create a new file called content-generation.php in the plugin’s directory. This file will contain the code for training the chatbot and generating content.
The first thing we need to do is to include the ChatGPT PHP library. We can do this with the following code:
require_once ‘path/to/chatgpt-php/src/chatgpt.php’;
Next, we need to create a new instance of the ChatGPT class. We’ll need to provide the path to the training data as a parameter to the constructor. In this example, we’re using a dataset of FAQs, which can be found here.
$chatbot = new ChatGPT(‘path/to/training data’);
Once the chatbot instance has been created, we can start training it. We’ll need to provide the number of iterations and the learning rate as parameters to the train() method. In this example, we’re using 1000 iterations and a learning rate of 0.01.
$chatbot->train(1000, 0.01);
Once the chatbot has been trained, we can start generating content. We’ll need to provide a prompt as a parameter to the generate() method. In this example, we’re using the prompt “What is ChatGPT PHP?”.
$content = $chatbot->generate(‘What is ChatGPT PHP?’);
The content that is generated will be in the form of a question and answer. The question will be the prompt that we provided, and the answer will be generated by the chatbot.
To output the content, we can use the following code:
echo ”; echo ‘
‘.$content[‘answer’].’
‘;
This will output the question and answer in an HTML heading and paragraph.
And that’s all there is to it! You can now use ChatGPT PHP to generate content for your WordPress site.
