Reference product on Order-confirmation.tpl

[pedluis]

Hello i'm trying to get some values of the order, specially prices and reference code of the product that the customer bought.

 

I've modified OrderConfirmationControler.php

    public function initContent()
    {
        parent::initContent();

        $this->context->smarty->assign(array(
            'is_guest' => $this->context->customer->is_guest,
            'HOOK_ORDER_CONFIRMATION' => $this->displayOrderConfirmation(),
            'HOOK_PAYMENT_RETURN' => $this->displayPaymentReturn()
        ));

        if ($this->context->customer->is_guest) {
            $this->context->smarty->assign(array(
                'id_order' => $this->id_order,
                'reference_order' => $this->reference,
                'id_order_formatted' => sprintf('#%06d', $this->id_order),
                'email' => $this->context->customer->email
            ));
            /* If guest we clear the cookie for security reason */
            $this->context->customer->mylogout();
        }
        $this->setTemplate(_PS_THEME_DIR_.'order-confirmation.tpl');
	      $order = new Order($this->id_order);
	      $cart = new Cart($order->id_cart);
		    $id_order = $this->id_order;
	      $description=""; 
          foreach ($cart->getProducts() AS $k=>$v)
            {
            $description.=$v['reference'];  
            }       
            
        $description = "['".$description."']";
        $this->context->smarty->assign(array(
        'total_products'=>$order->total_products,
        'description'=>$description,
        'id_order' =>$order->total_products
        ));
        $this->setTemplate(_PS_THEME_DIR_.'order-confirmation.tpl');
    }

And into the file order-confirmation.tpl i put this

<p>{$id_order|string_format:"%.2f"} </p>

<p>{$description}</p>
<p>[{$id_order|string_format:"%.2f"}]</p>
<p>{$total_products}</p>

On my test subdomain everything works, but in my official domain the reference code is not viewing.

I try to find where could be the problem, and it is into the foreach.

 

I don't know if there is any conflict because i'm getting always an empty value.

 

Anyone can help me?
