• Optimized Performance – Simplifies transactions with a dedicated payment method.
• Enhanced Security – Reduces exposure to multiple payment providers, improving risk management.
• Better User Experience – Provides a seamless and customized checkout process.

How to Develop a Single Payment Method Plugin in WordPress

Step 1: Create a New Plugin Folder

Navigate to the wp-content/plugins/ directory and create a new folder:

/wp-content/plugins/single-payment-plugin/
    - single-payment-plugin.php
    - includes/
    - assets/
    - templates/

Step 2: Define Plugin Metadata

Inside single-payment-plugin.php, add the following header:

<?php
/*
Plugin Name: Single Payment Method Plugin
Plugin URI: https://example.com/
Description: A custom single payment method plugin for WordPress.
Version: 1.0
Author: Your Name
License: GPL2
*/

Step 3: Register the Payment Gateway

Modify WooCommerce to recognize the payment gateway:

function register_single_payment_gateway($gateways) {
    $gateways[] = 'WC_Single_Payment_Gateway';
    return $gateways;
}
add_filter('woocommerce_payment_gateways', 'register_single_payment_gateway');

Step 4: Define the Payment Gateway Class

Create a class that handles the payment processing:

class WC_Single_Payment_Gateway extends WC_Payment_Gateway {
    public function __construct() {
        $this->id = 'single_payment';
        $this->method_title = __('Single Payment Method', 'woocommerce');
        $this->supports = array('products');
    }

    public function process_payment($order_id) {
        $order = wc_get_order($order_id);
        return array(
            'result'   => 'success',
            'redirect' => $this->get_payment_redirect_url($order),
        );
    }

    private function get_payment_redirect_url($order) {
        $return_url = site_url('/thank-you');
        return "https://example-payment.com/checkout?amount=" . $order->get_total() . "&currency=USD&return_url=$return_url";
    }
}

Step 5: Activate and Test the Plugin

• Upload the plugin folder to wp-content/plugins/.
• Activate it from the WordPress admin panel.
