hello,
I need to create a variable to show the promo code user in the twig confirmation template ex:{{ order.promo }}, but i don't know where the variables are stored in prestashop, or if that is the correct way to do it.
Help? thanks
EDIT: i've added on "OrderConfirmationController.php":
$regra = $this->context->cart->getCartRules();
$codigo = $regra[0]["code"];
$this->context->smarty->assign(array(
'HOOK_ORDER_CONFIRMATION' => $this->displayOrderConfirmation($order),
'HOOK_PAYMENT_RETURN' => $this->displayPaymentReturn($order),
'order' => $presentedOrder,
'register_form' => $register_form,
'codigo' => $codigo,
));
Returns nothing..
