Using HTTP_REFERER in Smarty TPL Files

[kgardener]

Hi all, any help on this problem would be massively appreciated, I am essentially looking to add a css file into the header.tpl if the http_referer equals utm_medium=cpc, now obviously in a php file I would use the below however I am not too familiar with Smarty and the best way of acheiving this in the header.tpl file

 

<?php

session_start();

if (!isset($_SESSION["origURL"]))

$_SESSION["origURL"] = $_SERVER["HTTP_REFERER"];

?>

 

 

<?php

$_SESSION['org_referer'] = $_SERVER['HTTP_REFERER'];

if (strpos($_SESSION['origURL'], 'utm_medium%3Dcpc') !== false)

echo "<link href="/themes/theme1/css/standard.css" rel="stylesheet" type="text/css" media="all" />";

else

echo "<link href="/themes/theme1/css/ppc.css" rel="stylesheet" type="text/css" media="all" />";

?>

 

Anyone with any thoughts on this or can point me in the right direction for some good resources to read up on?

you should create a simple module that performs a hookHeader. Your module will then be notified anytime the header is being created, and you then have the opportunity to add your .css file to the header section, based on your logic.
