Quick Syntax Question / PHP Include and Smarty

I am embedding Amember and the Popular Menalto Gallery v2, they both run on smarty I am integrating both to work as a photo gallery subscription service.

I have quick question regarding Syntax I am new to smarty I have the include syntax down to work but how can I get the following syntax to work with smarty.

PHP:


<?
$_product_id = array(1);

include("check.inc.php"); ?> 



Below What I have so far but I know the first part is not working, can anyone help. The include check.inc is working because I get the following error "Product ID is not defined in called script! Died." I just cant seem to get the "$_product_id = array(1);" part to work

Code:

  {php}
             
     $this->assign('$_product_id','1');
             
    include('check.inc.php');

   {/php}

Thank You

Has anyone managed to get this going at all, please?

If you're looking for a gallery2 plugin check with the helpdesk...I know they have one available and I toyed with it in the trial version.
