php - 用于插件开发的 WooCommerce 运输方法

Question

我一直在无休止地尝试向以下代码添加运输方式，但没有成功。好心人能否提供一些帮助。

我只需要添加一个送货方式。

基本上，代码所做的是将字段添加到 woo commerce 设置中的运输区域部分 |航运区。

我想添加一个[创建的区域的统一费率]

我到处搜索但没有运气。 :-(

<?php


 //Creating the Zone.

  function DW_shipping_zone_init() {



   // Getting the Shipping object
  $available_zones = WC_Shipping_Zones::get_zones();
  // Get all WC Countries
  $all_countries  = WC()->countries->get_countries();
  //Array to store available names
  $available_zones_names = array();
  // Add each existing zone name into our array
  foreach ($available_zones as $zone ) {
   if( !in_array( $zone['zone_name'], $available_zones_names ) ) {
     $available_zones_names[] = $zone['zone_name'];

   }
  }

  // Check if our zone 'C' is already there
  if( ! in_array( 'C', $available_zones_names ) ){
   // Create an empty object
   $zone_za = new stdClass();
   //Add null attributes
   $zone_za->zone_id = null;
   $zone_za->zone_order =null;
   // Add shipping zone name
   $zone_za->zone_name = 'C';
   // Instantiate a new shipping zone with our object
   $new_zone_za = new WC_Shipping_Zone( $zone_za );
   // Add South Africa as location
   $new_zone_za->add_location( 'ZA', 'country' );
   // Save the zone, if non existent it will create a new zone
   $new_zone_za->save();
   // Add our shipping method to that zone
   $new_zone_za->add_shipping_method( 'some_shipping_method' );
  }

add_action( 'init', 'DW_shipping_zone_init' );

你可以为此创建插件:

在 wp-content/pluigins/中创建一个名为“woocommerce-fast-delivery-system”的文件夹

在“woocommerce-fast-delivery-system”文件夹中，创建如下所示的两个文件:

1。快速交 cargo 输方法.php

<?php 
/*
Plugin Name: WooCommerce Fast Delivery Shipping Method
*/
/**
 * Check if WooCommerce is active
 */
$active_plugins = apply_filters( 'active_plugins', get_option( 'active_plugins' ) );
if ( in_array( 'woocommerce/woocommerce.php', $active_plugins) ) {
 add_filter( 'woocommerce_shipping_methods', 'add_fast_delivery_shipping_method' );
 function add_fast_delivery_shipping_method( $methods ) {
   $methods[] = 'WC_Fast_Delivery_Shipping_Method';
   return $methods;
 }
 add_action( 'woocommerce_shipping_init', 'fast_delivery_shipping_method_init' );
 function fast_delivery_shipping_method_init(){
   require_once 'class-fast-delivery-shipping-method.php';
 }
}

2。 class-fast-delivery-shipping-method.php

<?php

class WC_Fast_Delivery_Shipping_Method extends WC_Shipping_Method{

          public function __construct(){
                $this->id = 'fast_delivery_shipping_method';
                  $this->method_title = __( 'Fast Delivery Shipping Method', 'woocommerce' );

                  // Load the settings.
                  $this->init_form_fields();
                  $this->init_settings();


                  // Define user set variables

                  $this->title                 = $this->get_option( 'title' );


                  add_action( 'woocommerce_update_options_shipping_' . $this->id, array( $this, 'process_admin_options' ) );
          }

          public function init_form_fields(){
