I didn't understand your lang but the problrem is you are not using $_GET['menu'] to retrieve the GET parameter.

$menu = $_GET['menu'];
switch($menu) {
....
}

The "$menu = $_GET['menu'];" it works, but when I look at the first page provides a new error until you click for menu. – user2637387 Jul 31 '13 at 11:48

<a href="index.php?menu=profile">Profile</a>

<a href="index.php?menu=regisztracio">Regisztráció</a>

<a href="index.php?menu=kapcsolat">Kapcsolat</a>

here "menu " is not a php variable. You should pass value as $menu to switch ( $menu = $_GET['menu']; ). Not "menu" to switch.

$menu is undefined.

It is not set anywhere, e.g.

$menu  = "profile";
