Login User > PHP > problem ??

Hi,

I'm trying to setup a login page using Dreamweaver and PHP.

I've got the DB, the form, the fields and the code (from Dreamwaver MX
2004), but when I try to login, the confirmation page isn't displayed!?

Instead the URL looks like this:

/login.php?accesscheck=%2Fadmin%2Fsaisie.php

(login.php being the login page, saisie.php the confirmation page, admin
is the folder both files are in)

What went wrong and how do I correct that?

(When I'm using wrong login data, the page works correctly and displays
the login page again. The problem arises only when the page has
identified the login as valid ...)

Thanks a lot!

Takeshi
