当客户更改地址时发送通知电子邮件WooCommerce

Question

关于这个线程的后续：Woocommerce退款电子邮件
我有一个问题我似乎无法解决，我阅读了所有关于扩展WC_Email类的主题，该类具有自定义触发器，但我无法使其工作。

我想要实现的是添加一个电子邮件通知到WooCommerce电子邮件设置，并发送一封电子邮件给收件人，只要客户更新它的帐单或运输细节。

因此，在functions.php中，我将woocommerce_customer_save_address操作添加到woocommerce_email_actions中，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 extends WC_Email {

  public $woocommerce;
  public $current_user;

    /**

    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->recipient = $this->get_option( 'recipient' );

            )
        );
    }


}

endif;

return new WC_Customer_Address_Change_Email();

类本身可以工作，因为额外的电子邮件通知设置显示在WooCommerce设置中。
问题出在触发器调用中：

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

就是不开火。当我将此更改为：

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

并在后端完成一个订单,我确实会从类中获得一个附加的电子邮件,并带有我自己的电子邮件模板。

@birgire建议的将woocommerce_customer_save_address操作添加到woocommerce_email_actions的解决方案似乎不起作用？

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

对此有什么想法或变通办法吗？
可能值得一提，我正在与小贩主题的儿童主题工作，但这不应该？我正在使用Woocommerce 2.3.11和Wordpress 4.2.2

谢谢！

更新08-07-2015

我找到了解决办法。在functions.php中，我直接在woocommerce_customer_save_address操作中使用扩展的WC_Email类发送邮件：

// 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，我仍然可以从后端使用自定义类设置，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，Content-Type仍然设置为：text/html而不是text/plain，这会导致所有的换行符在模板中消失。在默认的WooCommerce电子邮件通知中，这确实可以正常工作。

我的猜测是$mailer->send调用中的$my_class->get_headers()参数不能正常工作。

有什么修复方法吗？
我可以在模板中手动设置内容类型吗？
谢谢

几周前，我为我的一个客户写了一个简单的插件，几乎就是为了这个目的。每当客户更改/更新其帐户数据时，这将发送电子邮件通知。

查阅我的代码，并从那里编辑/删除任何你不需要的东西。

 if( !class_exists('WooCommerceNotifyChanges') ){

class WooCommerceNotifyChanges{

    function __construct(){
        // customer saves main account data
        add_action('woocommerce_save_account_details', array( $this, 'woocommerce_send_notification' ));

        // customer saves billing or shipping data
        add_action('woocommerce_customer_save_address', array( $this, 'woocommerce_send_notification' ));
    }

    function woocommerce_send_notification(){
        $body       = '';
        $to         = '[e-mail]';    //address that will receive this email
        $subject    = 'One of your customers has updated their information.';

        $curr_user      = wp_get_current_user();
        $user_id        = $curr_user->ID;
        $curr_username  = $curr_user->data->user_login;

        $body .= '<table>';
        $body .= '<tr><td><strong>Account</strong></td></tr>';
        $body .= '<tr><td>Username: </td><td>' . $curr_username                                         . '</td></tr>';
        $body .= '<tr><td colspan="2">&nbsp;</td></tr>';
        $body .= '<tr><td colspan="2"><strong>Billing</strong></td></tr>';

        //send email

            //echo 'email sent';
        }else{

        }
