if(empty($_POST['loginname']) || empty($_POST['password']))
{
    $msg = "User or password is empty";
}
else
{
    if(login($_POST['loginname'], $_POST['password']) == true)
    {
        $usern = $_POST['loginname'];
        session_register('loginname');
        $loginname = $usern;        
        sleep(1);
            if(activestatus($_POST['loginname'], $_POST['password']) == true)
            {

             //header("Location: home.html"); 
            }

Turn on display_errors and set error_reporting to E_ALL, and you will see the error message "headers already sent" - you need to call setcookie (), BEFORE ANY HTML SEND. From php.net/setcookie:

setcookie() cookie HTTP . , cookie script ( ). , ,  , .

, :

<script>
function Redirect(url)
{
 location.href = url;
}

</script>

, cookie.

, , , script, $_SESSION cookie script , .

( ):

setcookie("ID_my_site", $_POST['loginname'], $hour,'/');

( ):

setcookie("ID_my_site", "$_POST['loginname']", $hour,'/');
