Groups

[Garcia]

Here is what I am trying to accomplish.

I set up an example page for groups.

-Displays an error for guests.
-Display an error for members who are not an admin (group 3).

I set up a table for members and a field called gid which is its group id. I set up a table for groups which have the groups and the id.

Now to protect a page for admins only I tried this:
[code]
<?php
session_start();
header("Cache-control: no-cache");

if($_SESSION['auth']) {
print "Welcome Member!";
}
else {
print "Welcome Guest!";
}

if($_SESSION['gid'] == 3{
print "Part of Admin Group";
}
else {
print "Not part of admin group";
}

?>
[/code]
That didn't work it did print Welcome Member but for everyone it including guests it did say Part of Admin Group. I am trying to accomplish user group protected pages, but not sure how to set it up properly. I may need to create a permissions table but not sure what to add with that.

Any help including code snippets or tutorials would be very appreciated.

Regards,
