添加自定义woocommerce电子邮件基于产品属性

Question

我试图适应在https://www.skyverge.com/blog/how-to-add-a-custom-woocommerce-email/

我的意图找到自定义邮件插件是，如果客户选择产品（它是一个变量的产品），其具有特定属性，当客户发出新的订单时（它必须发送它正在等待处理或处理），就会发送一封自定义电子邮件。

我的属性slu is是“csr-dates”。自定义插件由两个文件组成（见上面的链接）：woocommerce-csr-order-email.php和（存储在“includes”文件夹中）class-wc-csr-order-email.php

我想这个问题是在类文件，这是我到这里报到：

<?php

     // set ID, this simply needs to be a unique name 
     $this->id = 'customer_csr_order'; 
     $this->customer_email = true; 
     // this is the title in WooCommerce Email settings

       ) 
      ) 
     ); 
    } 


} // end \WC_CSR_Order_Email class 

我想，什么是错的代码，我写来获得属性（步骤1-2）和/或发送的条件电子邮件（步骤3）。

有人可以帮我解决这个问题吗？谢谢

Answer 1

而不是使用get_attribute()功能，你应该尝试使用get_attributes()这样：

//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)) 
{ 

试试吧，这应该工作...
