i dont have a database so what i would like to do is:
have admin.php where admins may enter a password. when they press submit i want it to go to a new page where the admins can edit stuff.
should i use sessions? i want it so that no one can just type in the URL of the page after the password, so i want it to work only if you enter the right password.
if u dont enter the right password, i want an invalid message.
