session immediate timeout

[neridaj]

Hello,

 

I don't know why this immediately redirects hen I hit the page:

 

session_start();
$_SESSION['valid_user'] = $username;
if(!isset($_SESSION['valid_user']))
header('Location:http://www.listingsbox.com');
die("Your session has expired!");

 

Thanks for any help,

 

J

sessions will only pass on the domain itself

 

if you're sending from

 

http://listingsbox.com

 

and redirecting to http://www.listingsbox.com it'll timeout

if it is due to the expiry of the session values then check and configure properly the session timeout values in the configuration files-php.ini.

Your posted code redirects when $username is not defined. The assignment statement setting the session variable to an un-defined variable, does not set the session variable.

$username is defined at login:

 

// include function files for this application
require_once('bookmark_fns.php'); 
session_start();

if ($username && $passwd)
// they have just tried logging in
{
  try
  {
    login($username, $passwd);
    // if they are in the database register the user id
    $_SESSION['valid_user'] = $username;
  }
  catch(Exception $e)
  {
  	echo $e->getMessage();
    // unsuccessful login
    do_html_header('Problem:');
    do_html_url('login.php', 'Login');
    do_html_footer();
    exit;
  }      
}
