I'm trying to use a plugin I found for Smarty - but no matter what I do - I can't get it to work within an X-cart template:

<?php
/**
 * Smarty plugin
 * @package Smarty
 * @subpackage plugins
 */


/**
 * Smarty {ie_detect} function plugin
 *
 * Type:     function

 * Name:     ie_detect

 * Date:     2.10.2004

 * Purpose:  Detect IE browser

 * Input:

 *
 * Example:    
 *  {ie_detect}
 *  {if $ie}
 *  <link rel="stylesheet" type="text/css" href="only-ie.css" />
 *  {else}
 *  <link rel="stylesheet" type="text/css" href="not-ie.css" />
 *  {/if}
 * @link http://smartbee.sourceforge.net/
 * @author   Martin Konicek <martin_konicek@centrum.cz>
 * @version  1.0
 * @param null
 * @param Smarty
 * @return boolen
 */
function smarty_function_ie_detect($params, &$smarty)
{
  $ie = strpos($_SERVER["HTTP_USER_AGENT"], 'MSIE') ? true : false;
  $ie = strpos($_SERVER["HTTP_USER_AGENT"], 'Opera') ? false : $ie;
  if($ie){
    $smarty->assign('ie', true);
  } else {
    $smarty->assign('ie', false);
  }
}

/* vim: set expandtab: */

?>

This is the plugin code which I placed into function.detect_ie.php into the smarty plugin directory...

into the head template I placed:

 {ie_detect}
 {if $ie}
 <link rel="stylesheet" type="text/css" href="only-ie.css" />
 {else}
 <link rel="stylesheet" type="text/css" href="not-ie.css" />
 {/if}

No matter how I tweak the code I can never get the $ie to return true or false... I know the plugin is being called - because I hardcoded

Just:

$smarty->assign('ie', "Is this working?");

And of course I was able to print it out on the template...

For some reason it's as though the $_SERVER["HTTP_USER_AGENT"] isn't functioning...

Can anyone give me code for a working IE detector?

Thank you so much!
