Creating Interactive Conversational Forms with ChatGPT PHP in a Custom WordPress Plugin
WordPress is a content management system (CMS) that enables you to create a website or blog from scratch, or to improve an existing website.
One of the most powerful features of WordPress is its extensibility – there are literally thousands of plugins available, each of which can add new features or functionality to your site.
In this tutorial, we’re going to build a custom WordPress plugin that will integrate ChatGPT into your site, allowing you to create interactive, conversational forms.
We’ll be using the ChatGPT PHP library to interact with the ChatGPT API. This library makes it easy to send and receive messages, and to create and manage forms.
To get started, create a new folder in your WordPress installation, called chatgpt-forms. Inside this folder, create a file called chatgpt-forms.php.
The first thing we need to do is include the ChatGPT PHP library. We can do this by adding the following line of code to our plugin file:
require_once( ‘path/to/chatgpt-php/lib/chatgpt-php.php’ );
Next, we need to register our plugin with WordPress. We can do this by adding the following code to our plugin file:
function chatgpt_forms_register_plugin() {
$args = array(
‘name’ => ‘ChatGPT Forms’,
‘description’ => ‘A plugin that integrates ChatGPT into your WordPress site.’,
‘version’ => ‘1.0’,
‘author’ => ‘Your Name’,
‘url’ => ‘https://your-site.com’,
);
register_plugin( ‘chatgpt-forms’, $args );
}
add_action( ‘plugins_loaded’, ‘chatgpt_forms_register_plugin’ );
This code registers our plugin with WordPress, and provides some basic information about it.
Now that our plugin is registered, we can start adding functionality to it.
The first thing we need to do is create a form. Forms are created using the ChatGPT PHP library, and are composed of a series of fields.
In this example, we’re going to create a simple contact form with three fields: Name, Email, and Message.
To create a form, we first need to create a new Form object. We can do this by adding the following code to our plugin file:
$form = new Form( ‘contact-form’ );
This code creates a new Form object, and gives it an ID of contact-form.
Next, we need to add fields to our form. We can do this by using the addField() method of the Form object.
In this example, we’re going to add three fields:
$form->addField( ‘name’, ‘text’ );
$form->addField( ’email’, ’email’ );
$form->addField( ‘message’, ‘textarea’ );
The first argument of the addField() method is the field ID, and the second argument is the field type.
In this example, we’ve created a text field, an email field, and a textarea field.
Now that our form is created, we need to add it to our WordPress site. We can do this by adding the following code to our plugin file:
$form->render();
This code will render the form on the page.
Now that our form is created, we need to add some functionality to it.
We’re going to use the ChatGPT PHP library to interact with the ChatGPT API. This will allow us to send and receive messages, and to create and manage forms.
First, we need to create a new ChatGPT object. We can do this by adding the following code to our plugin file:
$chatgpt = new ChatGPT( ‘your-chatgpt-api-key’ );
Replace your-chatgpt-api-key with your actual ChatGPT API key.
Next, we need to create a new FormManager object. This object will allow us to manage our form.
We can do this by adding the following code to our plugin file:
$form_manager = new FormManager( $chatgpt );
Now that we have a FormManager object, we can use it to manage our form.
To start, we need to register our form with the FormManager. We can do this by adding the following code to our plugin file:
$form_manager->registerForm( $form );
This code will register our form with the FormManager.
Next, we need to add a submit handler to our form. This handler will be called when the form is submitted.
We can do this by adding the following code to our plugin file:
$form->addSubmitHandler( ‘chatgpt_forms_submit_handler’ );
This code will add a submit handler to our form. The handler is a function that is defined in our plugin file.
The function takes two arguments: the form data, and the FormManager object.
The form data is an associative array that contains the data that was submitted in the form.
The FormManager object can be used to manage the form.
In this example, we’re going to use the FormManager to save the form data to a database.
First, we need to connect to our database. We can do this by adding the following code to our plugin file:
$db = new mysqli( ‘localhost’, ‘your-db-username’, ‘your-db-password’, ‘your-db-name’ );
Replace the placeholder values with your actual database credentials.
Next, we need to create a table to store our form data. We can do this by running the following SQL query:
CREATE TABLE IF NOT EXISTS chatgpt_forms (
id int NOT NULL AUTO_INCREMENT,
name varchar(255) NOT NULL,
email varchar(255) NOT NULL,
message text NOT NULL,
PRIMARY KEY (id)
);
This query will create a table called chatgpt_forms, with four fields: id, name, email, and message.
Now that our table is created, we can insert our form data into it. We can do this by adding the following code to our plugin file:
$sql = “INSERT INTO chatgpt_forms ( name, email, message ) VALUES ( ‘” . $db->real_escape_string( $form_data[‘name’] ) . “‘, ‘” . $db->real_escape_string( $form_data[’email’] ) . “‘, ‘” . $db->real_escape_string( $form_data[‘message’] ) . “‘ )”;
$db->query( $sql );
This code will insert our form data into the chatgpt_forms table.
Now that our form data is saved to our database, we can display it on our WordPress site.
To do this, we’re going to create a shortcode. Shortcodes are a WordPress feature that allows you to embed content in your posts and pages.
We can create a shortcode by adding the following code to our plugin file:
function chatgpt_forms_shortcode( $atts ) {
extract( shortcode_atts( array(
‘id’ => ”,
), $atts ) );
$output = ”;
$output .= ‘
Contact Form
‘;
$output .= ”;
$output .= ‘‘;
$output .= ”;
$output .= ‘‘;
$output .= ”;
$output .= ‘‘;
$output .= ‘‘;
$output .= ”;
$output .= ”;
return $output;
}
add_shortcode( ‘chatgpt_forms’, ‘chatgpt_forms_shortcode’ );
This code defines a function that generates the HTML for our form.
Then, we use the add_shortcode() function to register our shortcode.
Now that our shortcode is registered, we can use it to embed our form in any post or page on our WordPress site.
To do this, simply add the following shortcode to the post or page:
[chatgpt_forms]
This shortcode will render our form on the post or page.
And that’s
