Session Variables are lost after redirect with header

Question

i want to store some information in session variablle after login process. i can print the session variables in login post method succesfully. ie, i can fill the session variables. if the user logined succesfully, i redirected to index but my session variables becomes empty.

My Login Post page :

    if($totalRows_Recordset1>0)
    {
        session_start();
        $_Session['Mail']=$un;
        $_Session['Password']=$p;

        header("location: Index.php"); 
        die();

    }

My Index page :

<?php session_start(); echo $_Session['Mail']; ?>

Answer 1

$_SESSION needs to be capitalized, it's case sensitive. $_Session prints because you are declaring a local variable called $_Session. Let me know if it works :)

Answer 2

Yea....capitalize $_SESSION try this $_SESSION['mail']=$un;

Then in index page... echo $_SESSION['mail'];
