Php 如何为WooCommerce创建简单的离线支付网关？

下午好，我想在我的商店里制作一份货到付款（COD）的简单副本，并将其重命名为货到付款优惠券。 如何实施

向上 我尝试过此代码，但在WC设置页面上显示错误500：

<?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');

在WooCommerce插件中，您可以从管理部分启用支付网关COD：

管理>>商业>>设置>>结帐>>货到付款

选中启用COD的选项

请参阅下面的链接以创建脱机支付网关

在主插件文件中，您可以同时包含该类并过滤网关：

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' );

没有必要通过这种方式检查WooCommerce是否处于活动状态，因为只有在WooCommerce运行时，

WooCommerce\u支付\u网关才存在

然后在另一个名为

谢谢），但问题是，我需要COD和新的支付方法，它们与COD相同，但有另一个名称（交付时的优惠券）。换句话说，我需要2种离线支付方式。谢谢）但问题是，我需要COD和新的支付方式，这两种支付方式与COD相同，但有另一个名称（交付时优惠券）。换句话说，我需要2种离线支付方式。添加到问题中，在WooCommerce设置页面中显示错误500。类
