I would move the login page/code into the 'index.php' page as that's
where you are calling it from anyway.
index.php
1) session_start()
2) login link
3) if $_SESSION["validated"] == true then enable stuff
4) else don't enable stuff
login.php
1) session_start()
2) if username && password == allowed then $_SESSION["validated"] = true
2a) header("index.php")
3) else show login form
