php - WooCommerce Wordpress 插件问题

Question

出于某种原因，我的 CART 页面上显示了两个购物车总数。调试器中没有错误。

这是图片:

WooCommerce 有大量不同的文件。这是 cart-totals.php 页面。不确定这里是否有修复程序。

<?php
        /**
         * Cart totals
         *
         * This template can be overridden by copying it to yourtheme/woocommerce/cart/cart-totals.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.
         *

那是直接从插件文件夹中的 WooCommerce。该主题还有一个 WooCommerce 文件夹。这是主题中的 cart.php 页面:

            <?php do_action( 'woocommerce_after_cart' ); ?>

Answer 1

在你的主题 cart.php 中

<?php do_action( 'woocommerce_proceed_to_checkout' ); ?>

应该是:

<?php do_action( 'woocommerce_cart_actions' ); ?>
