如果满足某些条件，如何发送WooCommerce订单完成电子邮件

Question

在WooCommerce中，我尝试仅在订单状态从“处理中”更改为“已完成”（最多2天）时，向客户发送（审阅提醒）电子邮件。 strong>

类似： 如果订单= <2天并且当前订单状态已完成，请发送电子邮件。

add_action("woocommerce_order_status_changed", "customreminder_notification");

function customreminder_notification($order_id, $checkout=null) {    global $woocommerce;    $order = new WC_Order( $order_id ); $order_date = $order->order_date; $current_date = date('d.m.Y');

   if($order->status === 'completed' ) and $order_date = date('d.m.Y',strtotime("-2 days")) {
      // Create a mailer
      $mailer = $woocommerce->mailer();

      $message_body = __( 'Hello customer, please review our service: link.' );

      $message = $mailer->wrap_message(
        // Message head and message body.
        sprintf( __( 'Review reminder' ), $order->get_order_number() ), $message_body );


      // Cliente email, email subject and message.
     $mailer->send( $order->billing_email, sprintf( __( 'Review reminder' ), $order->get_order_number() ), $message );
     }

   }
