COD (Cashondelivery) module modification

[badyl]

Hi, I'm trying to pass order number to last step of COD - to confirmation.tpl
I've added line below to cashondelivery.php to hookPaymentReturn function (line before return;)

$order = new Order($params[0]);

In confirmation.tpl I have something like this:

Your order number: {$order}

but it doesn't work (displays only text, no number). Can You help?

Try the following instead:

$smarty->assign('order', $params[0]);

Unfortunately that doesn't work. I've added line like above and have blank screen on last confirmation after placing an order. I've got Prestashop 1.3.1, my files looks like this:

cashondelivery.php:

...
   public function hookPaymentReturn($params)
   {
       if (!$this->active)
           return ;

       $smarty->assign('order', $params[0]);
       return $this->display(__FILE__, 'confirmation.tpl');
   }

and confirmation.tpl:

{l s='Your order on' mod='cashondelivery'} {$shop_name}{l s='is complete.' mod='cashondelivery'}



   {l s='You have chosen the cash on delivery method.' mod='cashondelivery'}


{l s='Your order will be sent very soon.' mod='cashondelivery'}


Number of Your order: {$order}


{l s='For any questions or for further information, please contact our' mod='cashondelivery'} {l s='customer support' mod='cashondelivery'}.

Any ideas?
