How to display order ID in order-confirmation.tpl?

[mobster]

I can't put the total_products_wt in order-confirmation.tpl, could you help me?

 

I created in override/controllers/OrderConfirmationController.php

 

and put this cod:

 

class OrderConfirmationController extends OrderConfirmationControllerCore

{

public function displayContent()

{

global $cart;

 

self::$smarty->assign('total_products_wt', $cart->getOrderTotal(true, Cart::ONLY_PRODUCTS));

self::$smarty->assign('id_order', (int)$this->id_order);

 

parent::displayContent();

}

}

 

I put this line in order-confirmation.tpl:

 

{$total_products_wt}

 

But does not displays

 

 

 

PS version: 1.4.7.0

 

Thanks
