Hi,

To carry session from on page to another, Please do the following.
a) Open session before you can do anything on the page. In other words your first line of the page is <?php @session_start(); ?>
b) add values / variable to session i.e. $_SESSION['username'] = 'ajay';
$_SESSION['fburl'] = 'http://www.facebook.com/Amilextech';
etc.

c) When ever you need the session value, put <?php @session_start(); ?> as a first line of your page.

d) Get session values like $fb_link = $_SESSION['fburl']; echo $fb_link ;

Please check and let me know.

Thanks,
Ajay

Hi,

I check your code. Please do the following things
1) Make first linke is @session_start(). (before any include or require statement)
2) in loggedon.php comment line header('Location: login.php');
3) At the end of the code (after if statement) print session values i.e
print_r($_SESSION);

let me know what session values did you get.

Thanks,
Ajay
