Creating a Custom Chat Interface with ChatGPT PHP in a Custom WordPress Plugin
Posted on 18th June 2023
In this article, we’ll be creating a custom chat interface using the ChatGPT PHP SDK. This will allow us to easily integrate our chat interface into a custom WordPress plugin.
Getting Started
Before we get started, you’ll need to make sure you have the following:
- A ChatGPT account. You can sign up for one here.
- A WordPress site. You can download WordPress here.
- A text editor. We recommend Atom.
Creating the Plugin
The first thing we need to do is create a new folder for our plugin. For this example, we’ll call it “MyPlugin”.
Next, we need to create a new file in our “MyPlugin” folder. We’ll call this file “MyPlugin.php”.
In our “MyPlugin.php” file, we’ll need to add the following:
<?php
/*
Plugin Name: MyPlugin
Plugin URI: https://example.com/myplugin
Description: This is my plugin.
Version: 1.0
Author: John Doe
Author URI: https://example.com
*/
// Exit if accessed directly
if ( ! defined( 'ABSPATH' ) ) exit;
?>
This is the basic structure of a WordPress plugin. For more information, you can read the WordPress documentation on plugin development.
Adding the ChatGPT PHP SDK
Now that we have our plugin skeleton set up, we can start adding the ChatGPT PHP SDK. First, we need to download the SDK. You can find the latest version here.
Once you’ve downloaded the SDK, you’ll need to extract it and add the “src” folder to our “MyPlugin” folder.
Next, we need to include the ChatGPT PHP SDK in our plugin. We can do this by adding the following to our “MyPlugin.php” file:
<?php
// Exit if accessed directly
if ( ! defined( 'ABSPATH' ) ) exit;
// Include the ChatGPT PHP SDK
require_once plugin_dir_path( __FILE__ ) . 'src/ChatGPT/Autoloader.php';
?>
This will include the SDK in our plugin and allow us to use the SDK’s classes and methods.
Initializing the SDK
Now that we have the SDK included in our plugin, we need to initialize it. We can do this by adding the following to our “MyPlugin.php” file:
<?php
// Exit if accessed directly
if ( ! defined( 'ABSPATH' ) ) exit;
// Include the ChatGPT PHP SDK
require_once plugin_dir_path( __FILE__ ) . 'src/ChatGPT/Autoloader.php';
// Initialize the SDK
$options = array(
'api_key' => 'YOUR_API_KEY',
'api_secret' => 'YOUR_API_SECRET'
);
$chatgpt = new ChatGPTSDKChatGPT( $options );
?>
Replace “YOUR_API_KEY” and “YOUR_API_SECRET” with your ChatGPT API key and secret. You can find these in your ChatGPT account settings.
Creating the Custom Interface
Now that we have the SDK initialized, we can start creating our custom chat interface. First, we need to create a new file in our “MyPlugin” folder. We’ll call this file “MyPlugin-interface.php”.
In our “MyPlugin-interface.php” file, we’ll need to add the following:
<?php
// Exit if accessed directly
if ( ! defined( 'ABSPATH' ) ) exit;
// Include the ChatGPT PHP SDK
require_once plugin_dir_path( __FILE__ ) . 'src/ChatGPT/Autoloader.php';
// Initialize the SDK
$options = array(
'api_key' => 'YOUR_API_KEY',
'api_secret' => 'YOUR_API_SECRET'
);
$chatgpt = new ChatGPTSDKChatGPT( $options );
// Get the current user's ID
$user_id = get_current_user_id();
// Get the current user's name
$user = get_userdata( $user_id );
$username = $user->user_login;
// Get the current page URL
$page_url = $_SERVER['REQUEST_URI'];
// Get the current page title
$page_title = get_the_title();
// Initialize the ChatGPT PHP SDK
$options = array(
'api_key' => 'YOUR_API_KEY',
'api_secret' => 'YOUR_API_SECRET',
'page_url' => $page_url,
'page_title' => $page_title
);
$chatgpt = new ChatGPTSDKChatGPT( $options );
// Get the HTML for the chat interface
$chat_html = $chatgpt->getChatHTML();
// Output the chat interface
echo $chat_html;
?>
This will create a basic chat interface that you can easily customize to fit your needs.
Adding the Interface to the Plugin
Now that we have our custom chat interface created, we need to add it to our plugin. We can do this by adding the following to our “MyPlugin.php” file:
<?php
// Exit if accessed directly
if ( ! defined( 'ABSPATH' ) ) exit;
// Include the ChatGPT PHP SDK
require_once plugin_dir_path( __FILE__ ) . 'src/ChatGPT/Autoloader.php';
// Initialize the SDK
$options = array(
'api_key' => 'YOUR_API_KEY',
'api_secret' => 'YOUR_API_SECRET'
);
$chatgpt = new ChatGPTSDKChatGPT( $options );
// Get the current user's ID
$user_id = get_current_user_id();
// Get the current user's name
$user = get_userdata( $user_id );
$username = $user->user_login;
// Get the current page URL
$page_url = $_SERVER['REQUEST_URI'];
// Get the current page title
$page_title = get_the_title();
// Initialize the ChatGPT PHP SDK
$options = array(
'api_key' => 'YOUR_API_KEY',
'api_secret' => 'YOUR_API_SECRET',
'page_url' => $page_url,
'page_title' => $page_title
);
$chatgpt = new ChatGPTSDKChatGPT( $options );
// Get the HTML for the chat interface
$chat_html = $chatgpt->getChatHTML();
// Output the chat interface
echo $chat_html;
?>
This will add our custom chat interface to our plugin.
Conclusion
In this article, we’ve created a custom chat interface using the ChatG
As you can see, the code for our custom chat interface is very simple. The only thing we need to do is to call the chatGPT PHP function with the appropriate parameters. We can then use the returned data to display the chat interface in our WordPress plugin.
The chatGPT PHP function takes four parameters:
The first parameter is the URL of the chat server. This is the URL where the chatGPT PHP script is located.
The second parameter is the name of the chat room. This is the name of the chat room that you want to join.
The third parameter is the nickname of the user. This is the nickname that the user will use in the chat room.
The fourth parameter is the user’s IP address. This is the IP address of the user that will be used to identify the user in the chat room.
Once the chatGPT PHP function is called, the chat interface will be displayed in the WordPress plugin. The user can then chat with other users in the chat room.
