WooCommerce - 发送有关自定义订单状态更改的自定义电子邮件

我添加了自定义状态wc-order-confirmed:

// Register new status
function register_order_confirmed_order_status() {
    register_post_status( 'wc-order-confirmed', array(
        'label' => 'Potvrzení objednávky',
        'public' => true,
        'exclude_from_search' => false,
        'show_in_admin_all_list' => true,
        'show_in_admin_status_list' => true,
        'label_count' => _n_noop( 'Potvrzení objednávky <span class="count">(%s)</span>', 'Potvrzení objednávky <span class="count">(%s)</span>' )
    ) );
}
add_action( 'init', 'register_order_confirmed_order_status' );

// Add to list of WC Order statuses
function add_order_confirmed_to_order_statuses( $order_statuses ) {
    $new_order_statuses = array();
// add new order status after processing
    foreach ( $order_statuses as $key => $status ) {
        $new_order_statuses[ $key ] = $status;
        if ( 'wc-processing' === $key ) {
            $new_order_statuses['wc-order-confirmed'] = 'Potvrzení objednávky';
        }
    }
    return $new_order_statuses;
}
add_filter( 'wc_order_statuses', 'add_order_confirmed_to_order_statuses' );

我添加了自定义电子邮件wc_confirmed_order:

我可以在电子邮件设置中查看电子邮件，并在订单状态下拉列表中查看状态。现在，每当订单状态更改为时，我都需要发送新电子邮件wc-order-confirmed。过渡钩子似乎永远不会触发。

我也尝试过：

/**
 * Register the "woocommerce_order_status_pending_to_quote" hook which is necessary to
 * allow automatic email notifications when the order is changed to refunded.
 *
 * @modified from http://stackoverflow.com/a/26413223/2078474 to remove anonymous function
 */
add_action( 'woocommerce_init', 'so_25353766_register_email' );
function so_25353766_register_email(){
    add_action( 'woocommerce_order_status_pending_to_order_confirmed', array( WC(), 'send_transactional_email' ), 10, 10 );
    add_action( 'woocommerce_order_status_processing_to_order_confirmed', array( WC(), 'send_transactional_email' ), 10, 10 );
}

这似乎也根本不起作用......请问有什么想法吗？

您需要的钩子是：

woocommerce_order_status_changed

add_action("woocommerce_order_status_changed", "my_awesome_publication_notification");

function my_awesome_publication_notification($order_id, $checkout=null) {
   global $woocommerce;
   $order = new WC_Order( $order_id );
   if($order->status === 'completed' ) {
      // Create a mailer
      $mailer = $woocommerce->mailer();

      $message_body = __( 'Hello world!!!' );

      $message = $mailer->wrap_message(
        // Message head and message body.
        sprintf( __( 'Order %s received' ), $order->get_order_number() ), $message_body );


      // Cliente email, email subject and message.
     $mailer->send( $order->billing_email, sprintf( __( 'Order %s received' ), $order->get_order_number() ), $message );
     }

   }
}
