Session value doesnt pass on to the next page
<p>Basically I want to grab an id send via the url (ex. www.website.com/?id=432432) and take it accross my website till the user hits the contact page. I created a variable and a session variable </p>

<pre><code>session_start();
$getId = $_GET["id"];
$_SESSION['session_browser_test'] = $getId;
$adv_id = $_SESSION['session_browser_test'];
</code></pre>

<p>and used </p>

<pre><code>echo $adv_id; 
</code></pre>

<p>on my index.php Joomla template so it applies to all the pages. </p>

<p>But the issue is when i go to www.website.com/?id=432432 it echos the id on my web page, but if I click on the next link to go to another page (ex. www.website.com/nextPage)  it doesnt hold the session value from the previous page.  Why is that? and how can I carry the ID through out the site?</p>
