Я настроил файл шаблона checkout/review-order.php, чтобы включить функцию «удалить элемент» при оформлении заказа WooCommerce.
Причина в том, что я не знал, как сделайте то же самое с помощью крючка.
Цель состоит в том, чтобы иметь возможность удалить продукт из корзины прямо со страницы оформления заказа, используя файл functions.php вместо изменения шаблона.
Это модифицированная версия шаблона:
<?php
/**
* Review order table
*
* This template can be overridden by copying it to yourtheme/woocommerce/checkout/review-order.php.
*
* HOWEVER, on occasion WooCommerce will need to update template files and you
* (the theme developer) will need to copy the new files to your theme to
* maintain compatibility. We try to do this as little as possible, but it does
* happen. When this occurs the version of the template file will be bumped and
* the readme will list any important changes.
*
* @see https://docs.woocommerce.com/document/template-structure/
* @package WooCommerce/Templates
* @version 3.8.0
