I was trying to show status message against an ajax call. Was using rules_link to promote nodes clicking on a link. And wanted to show message if it was done. $commands = array(); $replaceData = array( '%userName%' => $order->getUserFullName(), '%userEmail%' => $order->getUserEmail(), '%userPhone%' => $order->getUserPhone(), '%userDeliver%' => $order->getUserDeliverTo(), '%orderId%' => $order->getId(), '%orderKey%' => $order->getKey(), '%orderLink%' => shop_url('cart/view/' . $order->getKey()), );
