使用購物車總項目添加woocommerce的自定義送貨方式

Question

我需要一些幫助來完成此代碼。我一直在嘗試爲我的woocommerce網站製作插件，以根據訂購的總項目自動添加運費。即，當我嘗試下面的代碼時，無論我訂購的物品數量多少，它都會返回11的值。理想siutation低於：

1-5包5000 6-10包萬 11-15包15000 16-20包20000

這裏是我下面的代碼。

<?php 
/* 
Plugin Name: Your Shipping plugin 
Plugin URI: http://woothemes.com/woocommerce 
Description: Your shipping method plugin

/**

if (in_array('woocommerce/woocommerce.php', apply_filters('active_plugins', get_option('active_plugins')))) { 

    function your_shipping_method_init() { 
     if (! class_exists('WC_Your_Shipping_Method')) { 
      class WC_Your_Shipping_Method extends WC_Shipping_Method { 
       /**

我從信用幫助：How to add custom shipping charge in woocommerce?得到了一些幫助，但現在我需要完成此操作。在此先感謝

Answer 1

它看起來像你的calculate_shipping功能有一些問題

if($carttotal < 20){ 
    $cost = 0;//Free delivery for above 20 packs 

應該

if($carttotal > 20){ 

和

}else if($carttotal >= 5 && $carttotal <= 1){ 

是倒退，它讀取「大於或等於到5且小於或等於1「

應該

}else if($carttotal >= 1 && $carttotal <= 5){ 

也是你最後不然，如果這種說法是混亂的，的休息，如果公司應該已經覆蓋1和20 +

}else if($carttotal > 1){ 
    $cost = 0; 

之間的每一個數字，您可能只需要刪除那部分。

Answer 2

我剛拆開的功能出了條件語句

if (in_array('woocommerce/woocommerce.php', apply_filters('active_plugins', get_option('active_plugins')))) { 

的不要忘記在底部最後的右括號。我殺了幾個標準，即不能使一個插件，但只是在我的functions.php

所以我的functions.php添加

require get_template_directory() . '/inc/woo-shipping-methods.php'; 

而且/公司製造一個新的文件（避免混亂），以包含/宇航運methods.php文件

有這個代碼

<?php 

function your_shipping_method_init() { 
    if (! class_exists('WC_Your_Shipping_Method')) { 
     class WC_Your_Shipping_Method extends WC_Shipping_Method {

       $this->method_description = __('Description of your shipping method'); // Description shown in admin 

       $this->enabled   = "yes"; // This can be added as an setting but for this example its forced enabled 
       $this->title    = "My Shipping Method"; // This can be added as an setting but for this example its forced. 

       $this->init(); 
      } 

      /*----------------------------------------------------------------

       // Save settings in admin if you have any defined 
       add_action('woocommerce_update_options_shipping_' . $this->id, array($this, 'process_admin_options'));

       if($carttotal > 20){

        $cost = 15000; 
       }else if($carttotal >= 6 && $carttotal <= 10){ 
        $cost = 10000; 
       }else if($carttotal <= 5 && $carttotal >= 1){ 
        $cost = 5000; 
       } 

       $rate = array(

       // Register the rate

      } 
     }

add_filter('woocommerce_shipping_methods', 'add_your_shipping_method');
