Up
I have tried this code, but it shows error 500 on WC settings page:
<?php
/**
* Plugin Name: My New WooCommerce Gateway
* Plugin URI:
* Description: WooCommerce gateway to ....
* Author: .....
* Version: 1.0
* Author URI: https://example.org/
* Text Domain: woocommerce-my-gateway
* Domain Path: /languages/
*/
add_action( 'plugins_loaded', 'init_my_gateway_class' );
function init_my_gateway_class() {
if ( !class_exists( 'WooCommerce' ) ) return;
class WC_Gateway_COD_Renamed extends WC_Payment_Gateway {
}
}
function add_my_gateway_class( $methods ) {
$methods[] = 'WC_Gateway_my_gateway';
return $methods;
}
add_filter( 'woocommerce_payment_gateways', 'add_my_gateway_class' );
function my_load_textdomain(){
load_plugin_textdomain( 'woocommerce-my-gateway', false, dirname( plugin_dir_path( __FILE__ ) . '/languages/' ) );
}
add_action('plugins_loaded', 'my_load_textdomain');

Answer 1

In your main plugin file you can include the class and filter the gateways at the same time:
function add_my_gateway_class( $methods ) {
include( 'class-wc-gateway-cod-renamed.php');
$methods[] = 'WC_Gateway_COD_Renamed';
return $methods;
}
add_filter( 'woocommerce_payment_gateways', 'add_my_gateway_class' );
There's no real need to check if WooCommerce is active this way as woocommerce_payment_gateways only exists if WooCommerce is running.
Then in another file called class-wc-gateway-cod-renamed.php you can define your class:
class WC_Gateway_COD_Renamed extends WC_Gateway_COD {
/**
* Setup general properties for the gateway.
*/
protected function setup_properties() {
$this->id = 'coupon-on-delivery';
$this->icon = apply_filters( 'woocommerce_coupon-on-deliver_icon', '' );
$this->method_title = __( 'Coupon on delivery', 'your-plugin' );
$this->method_description = __( 'Have your customers pay with a coupon upon delivery.', 'your-plugin' );
$this->has_fields = false;
}
/**
* Initialise Gateway Settings Form Fields.
*/
public function init_form_fields() {
$shipping_methods = array();
foreach ( WC()->shipping()->load_shipping_methods() as $method ) {
$shipping_methods[ $method->id ] = $method->get_method_title();
}
$this->form_fields = array(
'enabled' => array(
'title' => __( 'Enable/Disable', 'your-plugin' ),
'label' => __( 'Enable coupon on delivery', 'your-plugin' ),
'type' => 'checkbox',
'description' => '',
'default' => 'no',
),
'title' => array(
'title' => __( 'Title', 'your-plugin' ),
'type' => 'text',
'description' => __( 'Payment method description that the customer will see on your checkout.', 'your-plugin' ),
'default' => __( 'coupon on delivery', 'your-plugin' ),
'desc_tip' => true,
),
'description' => array(
'title' => __( 'Description', 'your-plugin' ),
'type' => 'textarea',
'description' => __( 'Payment method description that the customer will see on your website.', 'your-plugin' ),
'default' => __( 'Pay with coupon upon delivery.', 'your-plugin' ),
'desc_tip' => true,
),
'instructions' => array(
'title' => __( 'Instructions', 'your-plugin' ),
'type' => 'textarea',
'description' => __( 'Instructions that will be added to the thank you page.', 'your-plugin' ),
'default' => __( 'Pay with coupon upon delivery.', 'your-plugin' ),
'desc_tip' => true,
),
'enable_for_methods' => array(
'title' => __( 'Enable for shipping methods', 'your-plugin' ),
'type' => 'multiselect',
'class' => 'wc-enhanced-select',
'css' => 'width: 400px;',
'default' => '',
'description' => __( 'If coupon upon delivery is only available for certain methods, set it up here. Leave blank to enable for all methods.', 'your-plugin' ),
'options' => $shipping_methods,
'desc_tip' => true,
'custom_attributes' => array(
'data-placeholder' => __( 'Select shipping methods', 'your-plugin' ),
),
),
'enable_for_virtual' => array(
'title' => __( 'Accept for virtual orders', 'your-plugin' ),
'label' => __( 'Accept coupon if the order is virtual', 'your-plugin' ),
'type' => 'checkbox',
'default' => 'yes',
),
);
}
}
Extend the WC_Gateway_COD class so that you can inherit methods from it and only override the methods that have to do with the naming of things.

Answer 2

In WooCommerce plugin, you can enable payment gateway COD from admin section:
Admin >> WooCommerce >> Settings >> Checkout >> Cash on delivery.
Check option for enable COD.
