DIV 在结帐页面（WOOCOMMERCE）上生成 2 次？

Question

当用户点击运输详情复选框时，问题就开始了。当用户选中该框时，类order-detail-summary-outer 的 div 会自动生成。在结帐页面上，当用户选中运输详细信息时，订单摘要会加倍。我过去做了很多修改。所以我认为我犯了错误。点击运输信息复选框。订单摘要变为双倍。只有小计、运费和总计。

我在下面提供review-order.php文件代码

<?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

Answer 1

这件事可能来自很多方面，sql查询中的错误，重复div的javascript，...

如果它来自 php 方面，我不知道 WOOCommerce，但您可以在循环上应用 \array_unique() 方法来删​​除重复项（例如下面的代码作为解决方法）。

<?php foreach ( \array_unique(WC()->cart->get_coupons()) as $code => $coupon ) : ?>

https://www.php.net/manual/en/function.array-unique.php

PS : 但我确定这是 javascript 方面的错误。

Answer 2

一目了然。它看起来是您修改现有 HTML 结构的方式。 WooCommerce 使用大量 ajax 调用来更新该信息（购物车总数、结帐总数）。如果您修改了该结构并且它不知道将其发回/替换它的位置，它将注入一个新部分。

正如 LsKIT 所说，这是一个 JS 问题，但更多的是因为修改了 HTML。
