WooCommerce Installed: Make sure you have WooCommerce installed and configured on your WordPress site.
Development Environment: Set up a local development environment or a staging site to test your gateway.

Step-by-Step Guide to Create a WooCommerce Payment Gateway

Step 1: Create a Plugin

The first step in creating a custom payment gateway is to build a plugin. This will keep your code separate from the WooCommerce core files, allowing for easier updates and maintenance.

1. Create a Plugin Folder: In your WordPress installation, navigate to `/wp-content/plugins/` and create a new folder named `custom-payment-gateway`.

2. Create a Main Plugin File: Inside your new folder, create a PHP file named `custom-payment-gateway.php`. This will be the main file of your plugin.

3. Add Plugin Header: Add the following header to your PHP file to define your plugin:

 <?php /* Plugin Name: Custom Payment Gateway Description: A custom payment gateway for WooCommerce. Version: 1.0 Author: Your Name */

Step 2: Extend WooCommerce Payment Gateway Class

WooCommerce provides a payment gateway class that you can extend to create your custom gateway. This class contains methods and properties that you’ll need to define your payment gateway.

1. Include WooCommerce Payment Gateway: Add the following code to include the WooCommerce payment gateway class:

 if (!in_array('woocommerce/woocommerce.php', apply_filters('active_plugins', get_option('active_plugins')))) { return; }

add_action(‘plugins_loaded’, ‘init_custom_gateway_class’);

function init_custom_gateway_class() {

if (!class_exists(‘WC_Payment_Gateway’)) {

return;

}

class WC_Custom_Gateway extends WC_Payment_Gateway {

// Custom gateway code goes here

}

2. Define Gateway Properties: Within the `WC_Custom_Gateway` class, define the necessary properties such as ID, method title, and description.

 class WC_Custom_Gateway extends WC_Payment_Gateway { public function __construct() { $this->id = 'custom_gateway'; $this->method_title = __('Custom Gateway', 'woocommerce'); $this->method_description = __('Custom Payment Gateway for WooCommerce', 'woocommerce');

// Load the settings

$this->init_form_fields();

$this->init_settings();

$this->enabled = $this->get_option(‘enabled’);

$this->title = $this->get_option(‘title’);

// Save settings

add_action(‘woocommerce_update_options_payment_gateways_’ . $this->id, [$this, ‘process_admin_options’]);

}

Step 3: Add Gateway Settings

WooCommerce allows you to add settings fields to your payment gateway, enabling you to configure your gateway’s behavior from the admin panel.

1. Initialize Form Fields: Define the settings fields in the `init_form_fields` method.

 public function init_form_fields() { $this->form_fields = [ 'enabled' => [ 'title' => __('Enable/Disable', 'woocommerce'), 'label' => __('Enable Custom Gateway', 'woocommerce'), 'type' => 'checkbox', 'default' => 'no', ], 'title' => [ 'title' => __('Title', 'woocommerce'), 'type' => 'text', 'description' => __('Title that the user sees during checkout.', Explore this article on How To Delete Woocommerce From WordPress 'woocommerce'), 'default' => __('Custom Payment', 'woocommerce'), 'desc_tip' => true, ], ]; }

Step 4: Implement Payment Processing

Once you have defined your settings, the next step is to handle the payment processing logic. This involves validating and processing transactions with your payment provider.

1. Process Payment: Implement the `process_payment` method to handle the order and return the result.

 public function process_payment($order_id) { $order = wc_get_order($order_id);

// Here, you would send the payment details to your payment processor

// On success:

$order->payment_complete();

$order->reduce_order_stock();

// Return thank you page redirect

return [

‘result’ => ‘success’,

‘redirect’ => $this->get_return_url($order),

];

}

Step 5: Add to WooCommerce Payment Gateways

To make your custom gateway available in WooCommerce, you need to add it to the list of available payment gateways.

1. Add Gateway to WooCommerce: Use the `woocommerce_payment_gateways` filter to add your custom gateway.

 add_filter('woocommerce_payment_gateways', 'add_custom_gateway_class');

function add_custom_gateway_class($methods) {

$methods[] = ‘WC_Custom_Gateway’;

return $methods;

}

Testing Your Custom Gateway

After implementing all the necessary code, it’s essential to thoroughly test your custom payment gateway. Make sure to:

Test Transaction Flow: Simulate transactions to ensure everything works as expected.
Check for Errors: Look for any errors or issues in your WooCommerce logs.
Verify Settings: Ensure that all settings are correctly displayed and functional in the WooCommerce admin panel.
