woocommerce的taxonomy-product_cat分类模板也需要定义否则可能排版乱了

　　我们知道woocommerce（下称wc）的archive-product.php模板是定义shop page的，可能比较比较早版本的wc也是用这个文件来定义分类的，但是如果你升级到最新版本的wc会有一个单独的taxonomy-product_cat.php来定义产品分类模板，虽然是通过代码调用archive-product.php，

<?php /**  * The Template for displaying products in a product category. Simply includes the archive template  *  * This template can be overridden by copying it to yourtheme/woocommerce/taxonomy-product_cat.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     1.6.4  */   if ( ! defined( 'ABSPATH' ) ) {     exit; // Exit if accessed directly }   wc_get_template( 'archive-product.php' );

　　但一定要重新定义这个文件，特别是使用了独立pc和mobile模板，你可以复制一份archive-product.php然后重命名成taxonomy-product_cat.php，这样打开手机端的产品分类就不会出现页面错乱了。这是ytkah困扰了两天才得到的教训，希望有遇到相同问题的朋友借鉴。
