我想按类别对Woocommerce通知电子邮件中的项目进行排序。默认情况下,它们按客户选择它们的顺序排序。我什至不知道如何启动一些过滤器或功能...
我的类别如下:饮料,三明治,蔬菜等。
我找到了这段代码,但是它对我不起作用-没有任何结果。

* 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
