Creating a Simple WordPress Plugin with 6 AI Chatbots

In today’s digital landscape, AI chatbots have become increasingly popular for enhancing user engagement and providing instant support. As a WordPress developer or site owner, integrating AI chatbots into your website can significantly improve user experience and streamline communication. In this guide, we’ll walk through the process of creating a simple WordPress plugin that incorporates six different AI chatbots, giving your users a variety of options for interaction.

Why Create a Multi-Chatbot Plugin?

Before we dive into the technical details, let’s consider the benefits of offering multiple AI chatbots:

1. Diverse Functionality: Different chatbots excel at various tasks, from customer support to content recommendations.
2. User Preference: Visitors can choose the chatbot interface they find most comfortable or effective.
3. Fallback Options: If one chatbot service is down or unable to answer, others are available.
4. Comparative Analysis: Site owners can analyze which chatbots perform best for their specific audience.

Now, let’s get started with creating our plugin.

Step 1: Setting Up the Plugin Structure

First, create a new folder in your WordPress plugins directory (wp-content/plugins/) and name it “multi-ai-chatbots”. Inside this folder, create the main plugin file:

<?php
/*
Plugin Name: Multi AI Chatbots
Description: A simple plugin to integrate 6 AI chatbots into WordPress
Version: 1.0
Author: Your Name
*/

// Plugin code will go here

Step 2: Creating the Admin Settings Page

We’ll need an admin page to configure API keys and settings for each chatbot. Add the following code to your main plugin file:

function macb_add_admin_menu() {
    add_menu_page('Multi AI Chatbots', 'AI Chatbots', 'manage_options', 'multi-ai-chatbots', 'macb_admin_page');
}
add_action('admin_menu', 'macb_add_admin_menu');

function macb_admin_page() {
    // Admin page HTML and form will go here
}

function macb_register_settings() {
    register_setting('macb_settings', 'macb_chatbot1_api_key');
    register_setting('macb_settings', 'macb_chatbot2_api_key');
    // Add settings for other chatbots...
}
add_action('admin_init', 'macb_register_settings');

Step 3: Implementing the Chatbot Interfaces

For this example, we’ll assume we’re integrating with six popular AI chatbot services: ChatGPT, Dialogflow, IBM Watson, Amazon Lex, Microsoft Bot Framework, and Rasa. Each of these would typically require its own API integration. Here’s a simplified structure for how you might implement these:

function macb_chatgpt_interface($message) {
    $api_key = get_option('macb_chatbot1_api_key');
    // Implement ChatGPT API call here
    return $response;
}

function macb_dialogflow_interface($message) {
    $api_key = get_option('macb_chatbot2_api_key');
    // Implement Dialogflow API call here
    return $response;
}

// Implement similar functions for other chatbots...

Step 4: Creating the Front-End Interface

Next, we’ll create a simple front-end interface where users can select a chatbot and interact with it. Add this to your main plugin file:

function macb_enqueue_scripts() {
    wp_enqueue_script('macb-script', plugin_dir_url(__FILE__) . 'js/macb-script.js', array('jquery'), '1.0', true);
    wp_enqueue_style('macb-style', plugin_dir_url(__FILE__) . 'css/macb-style.css');
}
add_action('wp_enqueue_scripts', 'macb_enqueue_scripts');

function macb_add_chatbot_interface() {
    $html = '<div id="macb-chatbot-container">';
    $html .= '<select id="macb-chatbot-select">';
    $html .= '<option value="chatgpt">ChatGPT</option>';
    $html .= '<option value="dialogflow">Dialogflow</option>';
    // Add options for other chatbots...
    $html .= '</select>';
    $html .= '<div id="macb-chat-messages"></div>';
    $html .= '<input type="text" id="macb-user-input" placeholder="Type your message...">';
    $html .= '<button id="macb-send-button">Send</button>';
    $html .= '</div>';

    return $html;
}
add_shortcode('multi_ai_chatbots', 'macb_add_chatbot_interface');

Step 5: Handling AJAX Requests

To make the chatbot interactions dynamic, we’ll use AJAX. Add this to your main plugin file:

function macb_ajax_handler() {
    $message = $_POST['message'];
    $chatbot = $_POST['chatbot'];

    switch ($chatbot) {
        case 'chatgpt':
            $response = macb_chatgpt_interface($message);
            break;
        case 'dialogflow':
            $response = macb_dialogflow_interface($message);
            break;
        // Add cases for other chatbots...
        default:
            $response = "Error: Chatbot not found.";
    }

    echo json_encode(array('response' => $response));
    wp_die();
}
add_action('wp_ajax_macb_get_response', 'macb_ajax_handler');
add_action('wp_ajax_nopriv_macb_get_response', 'macb_ajax_handler');

Step 6: Creating the JavaScript File

Create a new file js/macb-script.js in your plugin directory:

jQuery(document).ready(function($) {
    $('#macb-send-button').click(function() {
        var message = $('#macb-user-input').val();
        var chatbot = $('#macb-chatbot-select').val();

        $.ajax({
            url: ajaxurl,
            type: 'POST',
            data: {
                action: 'macb_get_response',
                message: message,
                chatbot: chatbot
            },
            success: function(response) {
                var data = JSON.parse(response);
                $('#macb-chat-messages').append('<p><strong>You:</strong> ' + message + '</p>');
                $('#macb-chat-messages').append('<p><strong>AI:</strong> ' + data.response + '</p>');
                $('#macb-user-input').val('');
            }
        });
    });
});

Step 7: Styling Your Chatbot Interface

Create a new file css/macb-style.css in your plugin directory to style your chatbot interface:

#macb-chatbot-container {
    max-width: 400px;
    margin: 20px auto;
    border: 1px solid #ddd;
    padding: 20px;
    border-radius: 5px;
}

#macb-chat-messages {
    height: 300px;
    overflow-y: scroll;
    margin-bottom: 10px;
    border: 1px solid #eee;
    padding: 10px;
}

#macb-user-input {
    width: 70%;
    padding: 5px;
}

#macb-send-button {
    width: 25%;
    padding: 5px;
}

Finalizing Your Plugin

With these components in place, you now have a basic structure for a WordPress plugin that integrates six AI chatbots. To use it:

1. Activate the plugin in your WordPress admin panel.
2. Configure the API keys for each chatbot in the plugin settings.
3. Add the shortcode [multi_ai_chatbots] to any page or post where you want the chatbot interface to appear.

Remember, this is a simplified example. In a production environment, you would need to:

• Implement proper error handling and security measures.
• Fully integrate each chatbot’s API according to their specific requirements.
• Optimize the code for performance, especially if handling multiple API calls.
• Consider adding features like chat history, user authentication, and customization options.
