$_SESSION issues

Apparently I must not be thinking right today. I made a login, which set 2 session variables, and I cannot get the to echo when called later. And the issue I am havin now is checking if a user is logged in and, if not, redirecting them to the login page. Anyone see something wrong with this?

PHP Code:


		
			
<?php

      session_start();

      if(!isset($_SESSION['loggedin']) && $_GET['loc'] != 'login') {

        header('index.php?loc=login');

      }

    ?>

EDIT: The variable $_SESSION['loggedin'] can not be set, or even a blank string, because this is the only reference that exists of it so far.

In order to redirect you have to send the Location: header.

Code:

header('Location: index.php?loc=login');

Thank you very much. I so missed that. Now, as far as my echo to such. Just to make sure it is set, I altered the login check to:

PHP Code:


		
			
<?php

      session_start();

      if(!isset($_SESSION['user']) && $_GET['loc'] != 'login') {

        header('Location: index.php?loc=login');

      }

    ?>

And it continues, telling me $_SESSION['user'] is set. Now, a little down the page I run:

PHP Code:


		
			
 Logged in as: <? echo $_SESSION['user']; ?><br />

via an include(); file, but get no username to show. Any ideas?

Never mind. I just noticed I tossed a short tag in there. Fixed it and all is good. Thanks for the help.

Note that after a header() redirect you need to stop the script, such as with exit;. If you do not do that, the script will continue to process and execute whatever else the script does. For example if your page were there to delete something from your DB, it will still delete it even though the user was not logged in and got redirected.
