Create a front end for managing orders in wordpress using php and mongo db

Creating a front end for orders in WordPress using PHP and MongoDB involves several steps. You'll

need to set up a WordPress plugin, create a database connection to MongoDB, and design the UI for managing orders. Here's a simplified guide to get you started:

1. Set Up MongoDB:
   • Install and set up MongoDB on your server. You can follow the official MongoDB installation guide for your operating system: MongoDB Installation.
2. Install MongoDB PHP Driver:
   • Install the MongoDB PHP driver on your server. You can use Composer to install the MongoDB driver for PHP:

composer require mongodb/mongodb

1. Create a WordPress Plugin:
   • Create a new directory in the wp-content/plugins/ directory for your plugin.
   • Inside your plugin directory, create a main PHP file (e.g., orders-plugin.php).
2. Connect to MongoDB:
   • In your plugin PHP file, establish a connection to MongoDB:

<?php
require_once __DIR__ . '/vendor/autoload.php';

$client = new MongoDB\Client("mongodb://localhost:27017");
$db = $client->selectDatabase('your_database_name');

Create a Custom Post Type for Orders:

• Use WordPress hooks to create a custom post type for orders. Add the following code to your plugin:

function register_orders_post_type() {
    register_post_type('orders', [
        'label' => 'Orders',
        'public' => true,
        'show_ui' => true,
        'supports' => ['title', 'editor'],
    ]);
}

add_action('init', 'register_orders_post_type');

1. Design the Front End:
   • Create a WordPress page where users can manage orders. You can create a custom template for this page and include the necessary HTML, CSS, and JavaScript to display and interact with orders.
2. Handle Form Submissions:
   • Add a form on the orders management page to allow users to submit new orders. Use JavaScript to handle form submissions and send data to your server.
3. Save Orders to MongoDB:
   • Modify your PHP code to handle form submissions and save orders to MongoDB. Use the MongoDB PHP driver to insert documents into the MongoDB collection.

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $order_data = [
        'title' => sanitize_text_field($_POST['order_title']),
        'content' => sanitize_text_field($_POST['order_content']),
    ];

    $orders_collection = $db->selectCollection('orders');
    $orders_collection->insertOne($order_data);
}

Retrieve and Display Orders:

• Create a function to retrieve orders from MongoDB and display them on the orders management page.

function get_orders() {
    $orders_collection = $db->selectCollection('orders');
    $orders = $orders_collection->find();

    foreach ($orders as $order) {
        echo '<div class="order">';
        echo '<h2>' . esc_html($order['title']) . '</h2>';
        echo '<p>' . esc_html($order['content']) . '</p>';
        echo '</div>';
    }
}

• Call this function in your custom template to display orders.

Remember that this is a basic guide, and you may need to adapt it to your specific requirements and security considerations. Additionally, this example assumes a simple setup and doesn't cover advanced features like pagination, filtering, or error handling.
