根据产品属性添加自定义 woocommerce 电子邮件
Adding a custom woocommerce email based on the product attribute
我尝试调整 https://www.skyverge.com/blog/how-to-add-a-custom-woocommerce-email/
上的自定义电子邮件插件
我的意图是，如果客户选择具有特定属性的产品（它是可变产品），则在客户下新订单时会发送一封自定义电子邮件（必须发送待定或处理）。
我的属性鼻涕虫是"csr-dates"。自定义插件由两个文件组成（参见上面的 link）：woocommerce-csr-order-email.php 和（存储在 "includes" 文件夹中）class-wc-csr -顺序-email.php
我猜问题出在 class 文件中，我在这里报告：

我想我为获取属性（步骤 1-2）而编写的代码有问题 and/or 发送电子邮件的条件（步骤 3）。
有人可以帮我解决这个问题吗？谢谢
而不是使用 get_attribute() 函数你应该尝试这样使用 get_attributes():
//set 2) from the product_id get the product attribute
$product = new WC_Product( $product_id ); // create an object of WC_Product class
$patt = $product->get_attributes(); // call get_attributes method
//step 3) condition valid to send the email (if the attributes is csr-dates)
if ( array_key_exists('pa_csr-dates', $patt) )
{
试一试，这应该有效……
