Create "custom php page" without left column

[FreshCommerce]

Hello! I need help to achieve one adaptation. I´ve created a standalone webpage called "text.php" with this content:

 

include(dirname(__FILE__).'../../config/config.inc.php');
include(dirname(__FILE__).'../../header.php');
$smarty->display('test.tpl');

 

Is working fine, it shows the contents of "test.tpl" with my theme´s standar layout. Now I need in this test.tpl to NOT show left column. I´ve achieved this in other pages writing inside "header.tpl":

 

{if $page_name=='index' OR $page_name == 'product'}
....
{else}
...

 

But.. How to do this with my "custom created" test.php?? It won´t work using $page_name == 'test'...

I´ve changed the post title. Maybe now it´s more accurate.
