Undefined index: username HELP NEWBIE

Posted on 16th Feb 2014 07:03 pm by admin

I am trying a simple login/logout for my website. It works well with checking if the username exists in the database to logging in. I used $_SESSION['username']=$myusername; However, when I log-out, then I go to a page with this code

Code: <?php

session_start();

if($_SESSION['username']) //line5
echo "Welcome, ".$_SESSION['username']."!<br /><a href='logout.php'>Logout.</a>";
else
die ("You must be logged in!");

?>

It gives me an error. It says Notice: Undefined index: username in C:wampwwwdatbasmember.php on line 5

I just want to know how to fix this. Thank you
