当客户更改地址WooCommerce时发送通知电子邮件

关注此主题：Woocommerce Refund Email
我有一个问题，我可以't seem to fix, I read all the topics out there regarding extending the WC_Email class with a custom class with a custom trigger but I can' t让它工作 .

我想要实现的是向 WooCommerce Email 设置添加电子邮件通知，并在客户更新其帐单或运送详细信息时向收件人发送电子邮件 .

所以在我 functions.php 中我将 woocommerce_customer_save_address 动作添加到 woocommerce_email_actions 并添加我自己的 WC_Email 类扩展，如下所示：

<?php    
// Add a custom email action to the list of emails WooCommerce should load
add_action( 'woocommerce_init', function() { 
  add_action( 'woocommerce_customer_save_address', array( WC(), 'send_transactional_email' ), 10, 10 ); // WC 2.2-
});
add_filter( 'woocommerce_email_actions', 'add_customer_address_change_woocommerce_email_actions' ); // WC 2.3+
function add_customer_address_change_woocommerce_email_actions( $email_actions ) {
  $email_actions[] = 'woocommerce_customer_save_address';
  return $email_actions;
}
// Add a custom email class to the list of emails WooCommerce should load
add_filter( 'woocommerce_email_classes', 'add_customer_address_change_woocommerce_email_classes' );
function add_customer_address_change_woocommerce_email_classes( $email_classes ) {
    require_once( get_stylesheet_directory() . '/includes/class-wc-customer-address-change-email.php' );
    $email_classes['WC_Customer_Address_Change_Email'] = new WC_Customer_Address_Change_Email();
    return $email_classes;
}

这是我的自定义 WC_Customer_Address_Change_Email 类中的代码：

<?php
if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly
}

if ( ! class_exists( 'WC_Customer_Address_Change_Email' ) ) :

/**
 * A custom address change WooCommerce Email class
 *
 * @class       WC_Customer_Address_Change_Email
 * @version     2.3.0

 * @extends     WC_Email
 */
class WC_Customer_Address_Change_Email extends WC_Email {

  public $woocommerce;
  public $current_user;

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

        // set ID, this simply needs to be a unique name
        $this->id = 'wc_customer_address_changed';

        // this is the title in WooCommerce Email settings
        $this->title = __('Customer Address Change', 'monum');

        // this is the description in WooCommerce email settings
        $this->description = __('Address Change Notification emails are sent when a customer changes his billing or shipping address', 'monum');

        // these are the default heading and subject lines that can be overridden using the settings
        $this->heading = __('Customer Address Change', 'monum');
        $this->subject = __('Customer Address Change', 'monum');

        // 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/admin-address-change.php';
        $this->template_plain = 'emails/plain/admin-address-change.php';

        // Trigger on new paid orders
        //add_action( 'woocommerce_order_status_completed_notification', array( $this, 'trigger' ) );
        add_action( 'woocommerce_customer_save_address', array( $this, 'trigger' ) );

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

        // this sets the recipient to the settings defined below in init_form_fields()
        $this->recipient = $this->get_option( 'recipient' );

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

    }

                'description' => sprintf( __( 'Enter recipients (comma separated) for this email. Defaults to <code>%s</code>.', 'woocommerce' ), esc_attr( get_option('admin_email') ) ),

                'description' => sprintf( __( 'This controls the email subject line. Leave blank to use the default subject: <code>%s</code>.', 'woocommerce' ), $this->subject ),
                'placeholder' => '',

                'type'        => 'select',

                'options'     => $this->get_email_type_options()
            )
        );
    }


}

endif;

return new WC_Customer_Address_Change_Email();

该类本身有效，因为额外的电子邮件通知设置显示在WooCommerce设置中 .
问题在于触发器调用：

add_action( 'woocommerce_customer_save_address', array( $this, 'trigger' ) );

它只是不会开火 . 当我将其更改为：

add_action( 'woocommerce_order_status_completed_notification', array( $this, 'trigger' ) );

并在后端完成订单，我会从我们自己的电子邮件模板中收到一封额外的电子邮件 .

来自@birgire的建议解决方案将 woocommerce_customer_save_address 操作添加到 woocommerce_email_actions 似乎不起作用？

add_filter( 'woocommerce_email_actions', function( $email_actions ) {
    $email_actions[] = 'woocommerce_customer_save_address';
    return $email_actions;
});

对此有何想法或解决方法？
可能值得一提的是'm working with a child theme of the Peddlar theme but that shouldn't？我正在使用Woocommerce 2.3.11 和Wordpress 4.2.2

谢谢！

UPDATE 08-07-2015

我找到了解决方法 . 在我的 functions.php 中，我直接在 woocommerce_customer_save_address 动作中使用扩展的WC_Email类来发送邮件：

// Send notification email when customer saves address using custom extended WC_Email class
add_action( 'woocommerce_customer_save_address','notify_admin_customer_address_change', 10, 2);
function notify_admin_customer_address_change( $user_id ) {
  global $woocommerce;
    $mailer   = WC()->mailer();
    $My_Class = new WC_Customer_Address_Change_Email; // retrieve custom extended class 
  $mailer->send( $My_Class->get_recipient(), $My_Class->get_subject(), $My_Class->get_content(), $My_Class->get_headers(), $My_Class->get_attachments() );
}

这样我仍然可以使用后端的自定义类设置并使用WC_Email类功能 .

唯一不起作用的是，如果我将电子邮件类型设置为plain，则 Content-Type 仍设置为： text/html 而不是 text/plain ，导致我的所有换行符在我的模板中消失 . 在默认的WooCommerce电子邮件通知中，这可以正常工作 .

我猜是 $mailer->send 调用中的 $My_Class->get_headers() 参数无法正常工作 .

对此有任何修复？
我可以在模板中手动设置 Content-Type 吗？
谢谢
