How to use $_Session variables

[Ride]

I have a text box in the registration section where a new user can enter in a referer name.  I've got this type of url to work to automatically populate the field with the name in the string.... http://www.ridesocal.com/forum/index.php?action=register&ref=SomeMember

That is using $_REQUEST['ref'] in the registration.template

I'd like to use $_Session (that's what it is right?) to have my "ref" variable stay with the guest as they browse the site and when it comes time to register populate the referer text field.  I've tried a few things and haven't gotten it to work.  I'm guessing there is any easy answer to this.  Help!

Actually it's $_SESSION. Case is important.

I just got lazy typing.  I've been using all caps.  So any insight on how to do this?

You'd do something like:

if (isset($_REQUEST['ref']))
   $_SESSION['ref'] = $_REQUEST['ref'];

And then use $_SESSION['ref'] when appropriate.

Where would I put that first part?  In the registration.template.php file?

I suppose that would probably work.  If you want the ?ref=... to work from anywhere, put it in the init sub template (template_init) in index.template.php.

I'll try that tomorrow when I wake up.  Thank You!
