Php 我可以在Woocommerce电子邮件中按类别对订单项目进行排序吗

我想按类别对Woocommerce通知电子邮件上的项目进行排序，因为默认情况下，它们是按客户选择并添加到购物车的顺序进行排序的。在此方面的任何帮助都将不胜感激。谢谢

更改sql查询中的顺序

转到WoodPress管理员中的WooCommerce>设置。在“产品”选项卡上的“显示设置”下，更改默认的产品排序。

实际上，我已经在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，我的类别带有与仓库位置相关的编号-因此，将所有相同的位置放在一起确实有助于客户选择订单

该模板是旧版本，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.
