跟进此线程：Woocommerce 退款电子邮件 https://stackoverflow.com/questions/25544762/woocommerce-refund-email/26413223
我有一个似乎无法解决的问题，我阅读了有关使用带有自定义触发器的自定义类扩展 WC_Email 类的所有主题，但我无法让它工作。
我想要实现的是将电子邮件通知添加到WooCommerce 电子邮件设置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。
所以在我的函数.php我添加woocommerce_customer_save_address行动到woocommerce_email_actions并添加我自己的WC_Email类扩展如下：
<?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;
}
这是我的自定义代码WC_客户_地址_更改_电子邮件 class:
<?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
* @package WooCommerce/Classes/Emails
* @author WooThemes
* @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' );
}
/**
* trigger function.
*
* @access public
* @return void
*/
function trigger( $user_id ) {
$this->send( $this->get_recipient(), $this->get_subject(), $this->get_content(), $this->get_headers(), $this->get_attachments() );
}
/**
* get_content_html function.
*
* @access public
* @return string
*/
function get_content_html() {
ob_start();
wc_get_template( $this->template_html, array(
'email_heading' => $this->get_heading(),
'blogname' => $this->get_blogname(),
'sent_to_admin' => true,
'plain_text' => false
) );
return ob_get_clean();
}
/**
* get_content_plain function.
*
* @access public
* @return string
*/
function get_content_plain() {
ob_start();
wc_get_template( $this->template_plain, array(
'email_heading' => $this->get_heading(),
'blogname' => $this->get_blogname(),
'sent_to_admin' => true,
'plain_text' => true
) );
return ob_get_clean();
}
/**
* Initialise Settings Form Fields
*
* @access public
* @return void
*/
function init_form_fields() {
$this->form_fields = array(
'enabled' => array(
'title' => __( 'Enable/Disable', 'woocommerce' ),
'type' => 'checkbox',
'label' => __( 'Enable this email notification', 'woocommerce' ),
'default' => 'yes'
),
'recipient' => array(
'title' => __( 'Recipient(s)', 'woocommerce' ),
'type' => 'text',
'description' => sprintf( __( 'Enter recipients (comma separated) for this email. Defaults to <code>%s</code>.', 'woocommerce' ), esc_attr( get_option('admin_email') ) ),
'placeholder' => '',
'default' => ''
),
'subject' => array(
'title' => __( 'Subject', 'woocommerce' ),
'type' => 'text',
'description' => sprintf( __( 'This controls the email subject line. Leave blank to use the default subject: <code>%s</code>.', 'woocommerce' ), $this->subject ),
'placeholder' => '',
'default' => ''
),
'heading' => array(
'title' => __( 'Email Heading', 'woocommerce' ),
'type' => 'text',
'description' => sprintf( __( 'This controls the main heading contained within the email notification. Leave blank to use the default heading: <code>%s</code>.', 'woocommerce' ), $this->heading ),
'placeholder' => '',
'default' => ''
),
'email_type' => array(
'title' => __( 'Email type', 'woocommerce' ),
'type' => 'select',
'description' => __( 'Choose which format of email to send.', 'woocommerce' ),
'default' => 'html',
'class' => 'email_type wc-enhanced-select',
'options' => $this->get_email_type_options()
)
);
}
}
endif;
return new WC_Customer_Address_Change_Email();
该类本身可以正常工作，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' ) );
它就是不火。
当我将其更改为：
add_action( 'woocommerce_order_status_completed_notification', array( $this, 'trigger' ) );
在后端完成订单后，我确实收到了一封来自班级的额外电子邮件，其中包含我自己的电子邮件模板。
@birgire 建议的解决方案添加woocommerce_customer_save_address行动到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 主题的儿童主题，但这不应该吗？我正在使用 Woocommerce2.3.11和 WordPress4.2.2
Thanks!
UPDATE2015年8月7日
我找到了解决这个问题的方法。
在我的函数.php我直接在内部使用扩展的 WC_Email 类woocommerce_customer_save_address发送邮件的操作：
// 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(), $My_Class->get_attachments() );
}
这样我仍然可以使用后端的自定义类设置并使用 WC_Email 类功能。
唯一还不起作用的事情是，如果我将电子邮件类型设置为普通，内容类型仍设置为：文本/html代替文本/纯文本，导致我的所有换行符都消失在我的模板中。在默认的 WooCommerce 电子邮件通知中，这确实可以正常工作。
我的猜测是$My_Class->get_headers()中的参数$mailer->send呼叫无法正常工作。
有什么解决办法吗？
我可以设置内容类型手动在模板本身中？
Thanks
