Watson I added this code to the email templates but not working printf( __( 'Order: %s', 'woocommerce'), '<a href="$order->get_view_order_url()">'. $order->get_order_number() .'</a>' );`` I do not want to use any plugin paid/free.
anderson Hey Watson just replace that code with this printf( __( 'Order: %s', 'woocommerce'), '<a href="' . $order->get_view_order_url() . '">'. $order->get_order_number() .'</a>' );
