woocommerce 在结帐和购物车页面中更改价格

问题描述

使用 woocommerce，在我的网站中，我想在购物车页面中添加一个选择输入，用户可以在其中选择两个选项之间的值，并根据该值更改价格.

With woocommerce, in my website I'd like to add in the cart page a select input where the user can select a value between two options, and depending on this value I will change the price.

到目前为止，我可以获得总数并使用此更改它:

so far, I could get the total and change it using this :

function action_woocommerce_before_cart_totals(  ) { 
 global $woocommerce;

 $woocommerce->cart->total  = $woocommerce->cart->total*0.25;
   var_dump( $woocommerce->cart->total);}; 

问题是，当我去结帐页面时，它没有计算functions.php

The issue is that when I go to checkout page it doesn't take the total calculated in functions.php

谢谢你帮助我.

推荐答案

您也可以同时使用 woocommerce_review_order_before_order_total 钩子，在结帐时显示您的自定义价格，这样:

You can use woocommerce_review_order_before_order_total hook too at the same time, to display your custom price in checkout, this way:

add_action( 'woocommerce_review_order_before_order_total', 'custom_cart_total' );
add_action( 'woocommerce_before_cart_totals', 'custom_cart_total' );
function custom_cart_total() {

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
            return;

    WC()->cart->total *= 0.25;
    //var_dump( WC()->cart->total);
}

代码位于活动子主题(或主题)的 function.php 文件或任何插件文件中.

此代码已经过测试且有效.

This code is tested and works.
