Session create on a link?

lowsky13

I have a login using sessions. Is there a way to create a new session variable (add it to the existing session) when I click on a link? I want to make it so the session variable updates everytime I click on a link. Below it shows how it lists all files in a directory and makes a hyperlink so when clicked it spits out a url variable..which is good because my other page uses that but I am doing other things that are not working with the url variable..plus less secure...so how would I create(update) a sessions variable everytime someone clicks on one of these files?

if ($handle = opendir('shows/' . $_SESSION['username'])) {
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{

		$thelist .= '<a href="editshow.php?show=' . urlencode($file) . '">'
     . htmlspecialchars($file) . '</a><br>'; 


      }
   }

closedir($handle);
}
?>

<P>Select your show to manage:</p>
<P><?php echo $thelist ?>

Do you mean:

if (isset($_GET['show'])) {
    $_SESSION['show'] = $_GET['show'];
}

That is great...it works...I echoed out on the next page and get what I wanted...thanks.

Actually...it didn't work...I was calling another variable which was calling it. The session is not being created. Is there a certain place I need to put it so when it is clicked it creates (updates) the session variable?

Well you can put it anywhere before you want to use it. Beginning of the script (after session_start()) is a good place.

O.K. I had it on the wrong page...I realized that were were getting and realized that could only happen on the next page...put the code in the next page and it echos now. Thanks cahva.
