Hi

I just wanted some advice regarding my login script.

Example:
I have 2 types of user "Student" and "staff"

I would like both types of users which are in different tables to log into one login form, at the moment I have 2 separate scripts.

The general assumptions apply students shouldn't be able to access lecturers stuff and vice versa where relevant.

Everything is OK if I have to login forms but i would like to have it in one.

Language PHP SQL

Thanks in advance

        $_SESSION["valid_user"] = $_POST["studnum"];

Hi joban.ali,

when the user logs in (in the login page), store a $_SESSION variable to say whether thay are staff or student.

session_start();

if ($member == "staff"{
	$_SESSION['staff'] = "yes";
}
else{
	$_SESSION['student'] = "yes";
}

at the top of every page that is "staff only" add

session_start();
if (!isset($_SESSION['staff'])){
	header("location:login.php");
	exit();
}

and at the top of every "student only" page add

session_start();
if (!isset($_SESSION['student'])){
	header("location:login.php");
	exit();
}

This will check if the relevant $_SESSION variable has been set, and if not will redirect to login.php


Hope this helps.
