问题描述

我已尝试调整 https://www.skyverge.com/blog/how-to-add-a-custom-woocommerce-email/

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(必须发送它正在等待或处理中).

My intention is that if customer choose a product (it is a variable product) that has a specific attribute, a custom email is sent when the customer makes a new order (it has to be sent either it is pending or processing).

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

My atribute slug is "csr-dates". The custom plugin is composed (see the link above) by two files: woocommerce-csr-order-email.php and (stored in "includes" folder) class-wc-csr-order-email.php

我猜问题出在类文件中，我在这里报告:

I guess that the problem is in the class file, which I report here:

<?php

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

/**
 * A custom Order WooCommerce Email class
 *
 * @since 0.1
 * @extends WC_Email
 */
class WC_CSR_Order_Email extends WC_Email {


    /**
     * Set email defaults
     *
     * @since 0.1
     */
    public function __construct() {

        // 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
        $this->title = 'CSR Cruise Order';

        // this is the description in WooCommerce email settings
        $this->description = 'CSR Cruise Order Notification emails are sent when a customer places an order for a CSR cruise';

        // these are the default heading and subject lines that can be overridden using the settings
        $this->heading = 'CSR Cruise Order';
        $this->subject = 'CSR Cruise Order';

        // these define the locations of the templates that this email should use, we'll just use the new order template since this email is similar
        $this->template_html  = 'emails/customer-processing-order-csr.php'; //qui posso duplicare il template e farne uno ad hoc per questo tipo di mail con i file attached
        $this->template_plain = 'emails/plain/customer-processing-order.php';

        // Trigger on new paid orders

        // Call parent constructor to load any other defaults not explicity defined here
        parent::__construct();


        // if none was entered, just use the WP admin email as a fallback
        if ( ! $this->recipient )
            $this->recipient = get_option( 'admin_email' );
    }

          $order = new WC_Order( $order_id );

          //step 1) find first the product_id
          $items = $order->get_items();
          foreach ( $items as $item ) {
              $product_id = $item['product_id'];
          }

                $product = new WC_Product( $product_id );  // create an object of WC_Product class

                $patt = $product->get_attribute();  // call get_attribute method

            //step 3) condition valid to send the email (if the attributes is csr-dates)
            if ( $patt == 'pa_csr-dates'  ) 
            {
                //send the email
                // setup order object
                $this->object = new WC_Order( $order_id );
                $this->recipient    = $this->object->billing_email;

                // replace variables in the subject/headings

} // end WC_CSR_Order_Email class

我想我为获取属性(步骤 1-2)和/或发送电子邮件的条件(步骤 3)而编写的代码有问题.

I imagine that something is wrong in the code I wrote to get the attribute (step 1-2) and/or the condition to send the email (step 3).

有人可以帮我解决这个问题吗?谢谢

Could somebody help me in solve this problem? Thank you
