newbie question: variables not forwarded by assign() to .tpl file

[SlyFox]

I am new to prestashop and smarty/php, so sorry if my question is very easy to solve.

 

I try to display the shipping cost for 2 specific carriers in the shopping cart summary section (first screen during checkout procedure).

I found out I should calculate the cost for the 2 carrier in OrderController.php and forward the result to shopping-cart.tpl through the smarty-> assign() method.

 

I tried it with calculated results, and then with values I set staticly in an array and then separatly, but it still does not work.

 

Here is my code:

 

OrderController.php > initContent() > switch "loop"

default:

$this->_assignSummaryInformations();

/* $this->context->smarty->assign(array(

'aaa' => '333',

'bbb' => 444));*/

$this->context->smarty->assign('aaa', 333);

$this->context->smarty->assign('bbb', '444');

$this->setTemplate(_PS_THEME_DIR_.'shopping-cart.tpl');

break;

 

 

Where "aaa" and "bbb" should be displayed, the cell remains blank :-(

Here is the test I wrote in the shopping-cart.tpl file:

 

<p> Before if freight</p>

{if (!$aaa)}

<p> freightshipping not set and value is:{$aaa}(blank expected)</p>

{else}

<p> freighshipping is on and has value {$aaa}</p>

{/if}

<p> After if freight</p>

 

 

<p> Before if Air</p>

{if (!$bbb)}

<p> airshipping not set and value is:{$bbb}(blank expected)</p>

{else}

<p> airshipping is on and has value {$bbb}</p>

{/if}

<p> After if air</p>

 

In both cases, the variables are shown as not being known, and so nothing is printed on screen... :-(

 

I guess it's something very simple, but I just could not figure it out so far. Sorry again if it's really simple.

did you do this as an override? or did you edit the core order controller file?

Sorry for the very late answer :-/

I found my mistake. I was doing it as an override from a module. The problem was that I ad not reinstalled the module to update the overridden file in the prestashop/override folder...

newbie mistake....

 

I had not seen the email saying someone had answered, that's why I had not replied...sorry
