Need some help with PHP/MySQL

[Wabsta]

Okay, I managed to make a login, and a register script (it's for a school project btw).
But, it has to check if someone really logged in.

I've read something about sessions, but I didn't really get it.

So, can someone explain these Sessions to me?

session is like temporary informations on the userside, which are deleted when the user close its explorer or tab window.


to read those data, you need to initialize (allow PHP to access) the sessions on each page you need it with a session_start()

CODE

Wow, thanks, that was better than all those tutorials on the interwebs.

Because I finally get it now.
So, thanks, I'll try it tommorow morning in class

I hope your project will be successful.

Okay, I have this code now, but it doesn't work.
It's based on your idea Cyan.
Here it is:
CODE

It kinda works, as it makes me go to the site I inteded to go to (home.php, in home.php, there was a require "auth.php" which is this file), but if I go there again, it just gives me the login section again...
So probably, the session doesn't work.

Some information:
naam=name
wachtwoord=pass
verzonden=submit

These are some dutch words, that you may not figure out what it is

EDIT: I think it works now:
CODE

But how do I logout now?
I don't really get it..

EDIT 2:
NVM, figured it out.
