跟进此线程:Woocommerce Refund Email
我有一个似乎无法解决的问题，我阅读了所有关于使用带有自定义触发器的自定义类扩展 WC_Email 类的主题，但我无法让它工作。

我想要实现的是向 WooCommerce 电子邮件 设置添加电子邮件通知，并在客户更新其账单或运输详细信息时向收件人发送电子邮件。

所以在我的 functions.php 中，我将 woocommerce_customer_save_address 操作添加到 woocommerce_email_actions 并添加我自己的 WC_Email像这样的类扩展:

<?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

  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');

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

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

            )
        );
    }


}

endif;

return new WC_Customer_Address_Change_Email();

类(class)本身有效，因为额外的电子邮件通知设置显示在 WooCommerce 设置中。
问题出在触发器调用中:

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

它只是不开火。 当我将其更改为:

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

在后台完成订单后，我确实从类(class)收到了一封额外的电子邮件，其中包含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;
});

对此有什么想法或解决方法吗？
可能值得一提的是我正在使用 Peddlar 主题的 child 主题，但那不应该吗？我正在使用 Woocommerce 2.3.11 和 Wordpress 4.2.2

谢谢!

更新 08-07-2015

我找到了一个解决方法。 在我的 functions.php 中，我直接在 woocommerce_customer_save_address 操作中使用扩展的 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() );
}

这样我仍然可以从后端使用自定义类设置并使用 WC_Email 类功能。

唯一还行不通的是，如果我将电子邮件类型设置为纯文本，Content-Type 仍设置为:text/html 而不是text/plain，导致我所有的换行符在我的模板中消失。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() 参数无法正常工作。

有什么办法解决这个问题吗？
我可以在模板中手动设置Content-Type吗？
谢谢

最佳答案

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/更新他的帐户数据时，这将发送电子邮件通知。

查看我的代码并从那里编辑/删除您不需要的任何内容。

 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         = 'recipient@gmail.com';    //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>';

        //set content type as HTML
        $headers = array('Content-Type: text/html; charset=UTF-8;');

        //send email
        if( wp_mail( $to, $subject, $body, $headers ) ){
            //echo 'email sent';
        }else{
            //echo 'email NOT sent';                
        }
        //exit();
    }
}
new WooCommerceNotifyChanges();
