我创建了一个 Woocommerce 插件并要求它做两件事：
根据购物车中的产品变体，向特定电子邮件地址发送通知消息。
电子邮件必须仅包含相关产品，不得包含其他属性的产品。
例如：
产品 A 具有名为 Chef 的属性，其中 Chef-one 和 Chef-two 作为变量术语。用户可以从厨师一或厨师二中选择产品A。
如果用户从 Chef-one 选择产品 A，则必须将通知电子邮件发送至[电子邮件受保护] /cdn-cgi/l/email-protection包含所订购产品的名称（因为它会显示在常规 Woocommerce 通知电子邮件中）。
如果用户从厨师一中选择产品 A，从厨师二中选择产品 B，则必须向厨师一发送一封仅包含产品 A 的通知电子邮件，并且必须向厨师二发送一封仅包含产品 B 的通知电子邮件。
我已经使用上找到的教程创建了该插件https://www.skyverge.com/blog/how-to-add-a-custom-woocommerce-email/ https://www.skyverge.com/blog/how-to-add-a-custom-woocommerce-email/并对其进行了调整以适应上述目的。
我还修改了代码找到了以下解决方案：根据产品属性添加自定义 woocommerce 电子邮件 https://stackoverflow.com/questions/40633541/adding-a-custom-woocommerce-email-based-on-the-product-attribute
Woocommerce - 需要根据邮政编码将电子邮件发送到特定地址 https://stackoverflow.com/questions/26429482/woocommerce-need-to-send-email-to-specific-address-based-on-zip-code
这是我的插件类文件中的代码：

);
}
这是我所能得到的最接近的结果，但它不起作用。我怀疑问题出在“根据产品属性术语确定要发送到哪个电子邮件地址”这一行。该插件一直在加载，直到我添加该部分。
该函数应该位于单独的插件文件中吗？
我还需要帮助让电子邮件仅包含与其发送到的供应商相关的信息。
任何使该插件正常工作的帮助将不胜感激。
