I am working with PHP session variables, but the problem is that the session variables are not carrying over. I checked using Firebug, and found that the session variables are not being created at all. print_r($_SESSION); returns an empty array after the page returns to index.php, but displays it correctly before the refresh. logincheck.php:
<?php
session_start();
error_reporting(-1);
if(isset($_SESSION['logged_in']) && $_SESSION['logged_in']==true)
{
$username=$_SESSION['username'];
?>

Please help.
I think the under score is missing in on test.php page in $_SESSION['loggedin']=true; change this to $_SESSION['logged_in']=true;
As you are using this in
if(isset($_SESSION['logged_in']) && $_SESSION['logged_in']==true)
there is no error with you session part the error is may be in you db access part check your database connection. you can check you session by commenting the query part, it is working fine.
Spot the difference:
logincheck:
if(isset($_SESSION['logged_in']) && $_SESSION['logged_in']==true)
^^^^^^^^^
test:
$_SESSION["loggedin"]=true;
^^^^^^^^
One of these things is not like the other...
