loging out from a page and cant get username

[divinedesigns1]

EDIT: Just notice i foorgot to change the topic, anyway the topic suppose to be cant get username, since i fixed the logging out problem ok this is a small problem and im pretty much just over looking it, buttt i was trying to get the person name to be displayed on the main page by doing this

<?phpif($_SESSION['user']){echo "Welcome, " . $_SESSION['user'] = $username . "!";}else{die("You must be logged in");}?>

but instead of getting the username i just get Welcome, !. Which isnt what im trying to do ( ill be looking into this a little more ) just trying to get some pointers from here

did you set the session previously? to use session acrosss pages you have to start session using session_start() on top of the each page

[birbal]

and also if you want to check existance of variable isset() should be used. otherwise if you do if($somevar) then $somevar will type casted to boolean when it will be compared.when variable is not set it will be NULL and NULL to boolean type cassting is unpredictable and so have to avoid it

ok ill try that

and yes i started the session at the very top of the page, with the session_start()

it should be something like...

<?phpif(isset($_SESSION['user'])){echo "Welcome, {$_SESSION['user']}!";}else{die("You must be logged in");}?>
