PS 1.4 Order Confirmation specified Product

[m3442a]

Hello,

 

i want some specific parameters for the order-confirmation.tpl is a little bit complicated:

 

1. i have 4 specific products: If the customer order one of them, i want show the price for the product in the order-confirmation without tax, without shipping cost and - 4$ (or something) 

 

2. i have normal products:  If the customer order one of them, i want show the price for the product in the order-confirmation without tax and without shipping cost.

 

3. if the customer order  both products togehther, than doing the same action for both products.

Than i need the cart products without tax and shipping price - 4$.

 

So i try for the first step an override for the  total_products parameters in Hook.php:

 

public static function paymentReturn($id_order, $id_module)

{

   if (Validate::isUnsignedId($id_order) AND Validate::isUnsignedId($id_module))

   {

$params = array();

$order = new Order((int)($id_order));

$currency = new Currency((int)($order->id_currency));

   

    if (Validate::isLoadedObject($order))

    {

$params['total_to_pay'] = $order->total_paid;

$params['total_products'] = $order->total_products - $order->total_shipping - $order->total_wrapping + $order->total_discounts;

$params['currency'] = $currency->sign;

$params['objOrder'] = $order;

$params['currencyObj'] = $currency;

 

return Module::hookExec('paymentReturn', $params, (int)($id_module));

}

   }

   return false;

}

 

in the order-confirmation.tpl  and payment modules i have the variable total_products and that works.

 

But how can i change the variable to specific product ID?

 

Something like this:

 

if $product_id  == '1' OR  == '2' {

$params['total_products'] = $order->total_products - $order->total_shipping - $order->total_wrapping + $order->total_discounts -4$;

}

else

{$params['total_products'] = $order->total_products - $order->total_shipping - $order->total_wrapping + $order->total_discounts;}
