session help!!

[gingar]

I've this problem getting the session variable on the next page.

on login, i have this code to set the variables.

<?
        ob_start();
	session_start();

    session_unregister('login');
session_unregister('name');
session_unregister('id');

$pg = trim($_GET['pg']);

if (isset($_POST['p_em']))
{
	$_SESSION['login'] = trim($_POST['p_em']);
	$_SESSION['name'] = trim($_POST['p_fname']) . " " . trim($_POST['p_lname']);
	$_SESSION['id'] = trim($_POST['p_id']);
}

if (isset($_GET['p_em']))
{
	$_SESSION['login'] = trim($_GET['p_em']);
	$_SESSION['name'] = trim($_GET['p_fname']) . " " . trim($_GET['p_lname']);
	$_SESSION['id'] = trim($_GET['p_id']);
}

if ($_SESSION['login'] != "")
      {		
         header("Location: loggedin.php");
      }	
      else
      {
         header("Location: notlogin.htm");
      }
?>

i am able to print out the session values at the end of this page. However, when the page gets redirected to the next page, loggindin.php, the session values are lost!

<?php
//loggindin.php
   ob_start();
	session_start();

print "<br>login:".$_SESSION['login'];

?>

the login page and the loggedin.php are opened in the same frame btw.

anybody have any idea why i cant get the session on the next page?

use session_write_close() then header() then die()

[gingar]

i put it here.. and its still not working..

if ($_SESSION['login'] != "")
      {	
         session_write_close();	
         header("Location: loggedin.php");
         //print "ok";
      }	
      else
      {
         header("Location: login.htm");
         //print "not ok";
      }

on which page do i do that?

try killing off the output buffering, and don't forget to die() after doing the header() call.
