php session doesn't work

Question

How it should work: Index.php is the secured page. It includes check.php, which checks if you have a session = good. If it hasn\'t, you\'re not logged in -> log off, remove sess

Answer 1

if($count==1){
    session_start();    
    $_SESSION['Username'] = $UserName;
    $_SESSION['Password'] = $password;
    UpdateOnlineChecker($Session);
    header( "Location: http://". strip_tags( $_SERVER ['HTTP_HOST'] ) ."/newHolo/" );
    exit;
}
else {
    echo "Wrong Username or Password";
}

Look at my code. It checks if the statement is true (for me, if there is one row with a query statement i execute). Then i start a session and basically Ill define global session variables, sned out a query to my database to update the session and then refer through.

you are missing a session_start(); in your if true block.
