a na pocetku stranice rezervacija.php funkciju isloged() koja proverava da li je korisnik ulogovan i ako nije vraca ga na stranicu login.php
Code:
function isloged()
{
if (empty($_SESSION['user_name']) and $_SESSION['SID']!=session_id())
{
header("Location: login.php");
exit();
}
}
function isloged()
{
if (empty($_SESSION['user_name']) and $_SESSION['SID']!=session_id())
{
header("Location: login.php");
exit();
}
}
e sad kad probam da se ulogujem on me vraca na stranicu login.html i nista se ne desava. proverio sam sto puta i nigde se nista ne salje na izlaz sto znaci da bi header() trebalo da radi, ali ne radi. ako neko vidi u cemu je problem, neka mi kaze molim vas...
