php - 我可以在 Woocommerce 电子邮件中按类别对订单商品进行排序吗

Question

我想按类别对 Woocommerce 通知电子邮件中的商品进行排序，因为默认情况下，它们按客户选择商品并将其添加到购物车的顺序进行排序。在这方面的任何帮助将不胜感激。谢谢

Answer 1

我实际上在 email-order-items.php 中添加了一个解决方案 - 这会将类别添加到管理电子邮件中并使用类别进行排序(我的类别中包含与仓库位置相关的数字 - 因此拥有所有相同的地点在一起确实有助于客户挑选订单。)

模板是旧版本，但仍然有效

//**
 * Email Order Items
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/emails/email-order-items.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/
* @author       WooThemes
* @package  WooCommerce/Templates/Emails
* @version     3.0.0
