使用购物车总项在woocommerce中添加自定义运输方法

Question

我需要有人帮我完成这段代码。我一直试图为我的woocommerce网站做一个插件，以便根据订购的总项目自动添加运输成本。当我尝试下面的代码时，它会返回一个11 ie的值，而不管我订购的项目数量如何。理想的选择如下：

1-5包5 000 6-10包10 000 11-15包15 000 16-20 000包

下面是我的代码。

我得到了来自Credit：How to add custom shipping charge in woocommerce?的一些帮助，但现在我需要完成这个任务。提前感谢

Answer 1

看起来您的calculate_shipping函数有一些问题

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

应该是

if($carttotal > 20){

和

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

则为“大于或等于5，小于或等于1”。

应该是

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

另外，如果最后一个语句令人困惑，则if的其余部分应该涵盖了1和20+之间的所有数字

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

你也许可以把那部分去掉。

Answer 2

我只是从条件语句中解压缩函数。

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

不要忘记在底部的最后的结束支撑。我杀了一些标准，即不让它成为插件，而只是制作了一个新文件(避免杂乱)，以便包含在我的functions.php中。

因此，对于functions.php，我添加了

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

和/inc/woo-航运-方法. And文件

有这个代码

<?php

    if ( ! class_exists( 'WC_Your_Shipping_Method' ) ) {
