Send notification email when customer changes address

  • Hi there,

    I have a problem I can’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 get it to work.

    What I would like to achieve is to add an email notification to the WooCommerce Email settings and send an email to the recipient whenever a customer updates it’s billing or shipping details.

    So in my functions.php I add the woocommerce_customer_save_address action to the woocommerce_email_actions and add my own WC_Email class extension like this:

    // Add a custom email action to the list of emails WooCommerce should load
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;
}

    This is my code in my custom WC_Customer_Address_Change_Email class:

    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

 */
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_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' => __( 'Choose which format of email to send.', 'woocommerce' ),

                'class'       => 'email_type wc-enhanced-select',
                'options'     => $this->get_email_type_options()
            )
        );
    }

}

endif;

return new WC_Customer_Address_Change_Email();

    The class itself works because the extra e-mail notification setting shows up in the WooCommerce settings. The problem lies within the trigger call:

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

    It just doesn’t fire. When I change this to:

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

    And complete an order in the backend, I do get an additional email from the class with my own custom email template.

    The suggested solution to add the woocommerce_customer_save_address action to the woocommerce_email_actions doesn’t seem to work?

    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;
}

    So I made a workaround for this.
    In my functions.php I use my extended WC_Email class directly inside the woocommerce_customer_save_address action to send the mail:

    // 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() );
}

    That way I can still use my custom class settings to get my headers, subject, template paths, recipient and content and use the WC_Email class functionality.

    The only thing that isn’t working yet are the headers;
    If I set the email type to plain in the notification settings, the Content-Type is still set to: text/html instead of text/plain, causing all my line-breaks to disappear in my template. In the default WooCommerce email notifications this does work correctly.

    My guess is the $My_Class->get_headers() parameter in the $mailer->send() call doesn’t work. I already tried:

    $mailer->get_headers()
WC_Email::get_headers()
$WC_Email = new WC_Email;
$WC_Email->get_headers()

    Setting the Content-Type manually in the template doesn’t work either.
    I am using Woocommerce 2.3.11 and WordPress 4.2.2

    Any thoughts on this?
    Thanks!
