Adding a new payment gateway on woocommerce

Adding a new payment gateway to WooCommerce involves several steps. Here's a step-by-step guide to help you through the process:

Step 1: Create a new folder and file structure

Create a new folder in the wp-content/plugins directory of your WordPress installation. For example, you can name it woocommerce-payment-gateway.

Inside this folder, create the following files:

woocommerce-payment-gateway.php (the main plugin file)
includes folder (for any additional files you might need)
languages folder (if you want to translate your plugin)

Step 2: Define the plugin metadata

In the woocommerce-payment-gateway.php file, add the following code to define the plugin metadata:

<?php
/*
Plugin Name: WooCommerce Payment Gateway
Description: A new payment gateway for WooCommerce
Version: 1.0
Author: Your Name
Author URI: https://yourwebsite.com
*/

Step 3: Create the payment gateway class

Create a new file in the includes folder, e.g., payment-gateway.php. In this file, define a class that extends the WC_Payment_Gateway class:

<?php
class WC_Payment_Gateway_Your_Gateway extends WC_Payment_Gateway {
    // Your payment gateway code goes here
}

Step 4: Define the payment gateway settings

In the payment-gateway.php file, define the payment gateway settings, such as the title, description, and form fields:

public function __construct() {
    $this->id = 'your_gateway_id';
    $this->method_title = 'Your Payment Gateway';
    $this->method_description = 'A new payment gateway for WooCommerce';
    $this->has_fields = true;

    $this->init_form_fields();
}

public function init_form_fields() {
    $this->form_fields = array(
        'title' => array(
            'type' => 'text',
            'label' => 'Title',
            'description' => 'The title of your payment gateway',
        ),
        'description' => array(
            'type' => 'textarea',
            'label' => 'Description',
            'description' => 'The description of your payment gateway',
        ),
        // Add more form fields as needed
    );
}

Step 5: Define the payment gateway processing

In the payment-gateway.php file, define the payment gateway processing logic, such as handling the payment form submission and processing the payment:

public function process_payment($order_id) {
    // Your payment processing code goes here
    // For example:
    $order = wc_get_order($order_id);
    $payment_method = $this->get_payment_method();
    $payment_gateway = new WC_Payment_Gateway_Your_Gateway();
    $payment_gateway->process_payment($order, $payment_method);
}

Step 6: Add the payment gateway to WooCommerce

In the woocommerce-payment-gateway.php file, add the following code to add the payment gateway to WooCommerce:

function woocommerce_payment_gateway_init() {
    WC_Payment_Gateway_Your_Gateway::init();
}
add_action('woocommerce_payment_gateways', 'woocommerce_payment_gateway_init');

Step 7: Test the payment gateway

Test your payment gateway by going to the WooCommerce settings page and enabling the new payment gateway. Then, try processing a payment using the new gateway to ensure it works correctly.

That's it! With these steps, you should now have a new payment gateway added to WooCommerce.
