Switch Case code to redirect from a link based on session variable

I'm writing a web app (php/mysql) for a college with 29 departments. I have a login page which checks username and password against the DB and if it finds the user also pulls down an access_level variable:

$loginStrGroup = mysql_result($LoginRS,0,'access_level');

//declare two session variables and assign them
$GLOBALS['MM_Username'] = $loginUsername;
$GLOBALS['MM_UserGroup'] = $loginStrGroup;

//register the session variables
session_register("MM_Username");
session_register("MM_UserGroup");

Then, based upon the access_level stored in $loginStrGroup, I redirect the logged in user to one of five pages by means of a switch case expression:

switch ($loginStrGroup) {
case 1:
header("Location: switchboard01.php");
break;
case 2:
header("Location: switchboard02.php");
break;
case 3:
header("Location: switchboard03.php");
break;
case 4:
header("Location: switchboard04.php");
break;
case 5:
header("Location: switchboard05.php");
}

All that works perfectly. Here's my problem -- some pages in the app need to be shared by users with different access levels. On one such page I have a link back to the switchboard, but it's a hard-coded link and returns all users back to just one switchboard.

How can I reference the session variable $loginStrGroup in such a way that any user who clicks the link will be sent back to his/her proper switchboard? I've tried a few variations in code but can't get it to work.

Thanks.

Would something like this work?



Though it looks like it would be just as easy to set up your links to the switchboard like this, too:



as long as the $loginStrGroup is an integar that matches up with the proper switchboard file.

Madpawn,

Here's how I did it:

Declared additional Globals on the login page:
//declare three session variables and assign them
$GLOBALS['MM_Username'] = $loginUsername;
$GLOBALS['MM_UserGroup'] = $loginStrGroup;
$GLOBALS['MM_UserHomePage'] = 'switchboard0'.$loginStrGroup.'.php';
//register the session variables
session_register("MM_Username");
session_register("MM_UserGroup");
session_register("MM__UserHomePage");

Then formatted the link on the shared page this way:
Back to <?php echo "<a href='switchboard0".$GLOBALS['MM_UserGroup'].".php'> Switchboard </a>"; ?>

It works very well.

Your code would have worked too, except I could not get the $loginStrGroup variable to pass consistently.

Thanks for the reply.
