Hi,

I'm using for my website script and upon users logging in a
is set. Problem for me is that the doesn't work due to headers
already sent. Is there anyway of fixing this because, there is no possible
way of adding set() to the top of the PHP file when the is
holding the username from the POSTed form. Any appreciated.

This must be a self imposed restriction on your side, coz' otherwise I
see no problem.

What I mean is I cannot use set, I need to check if user credentials
are correct first (which is BEFORE set) and if so, set a . I
can't do that unless set is first, but I need to check if the user
credentials is correct. Furthermore I cannot use set in the header as
I want to display a message saying that they have successfully logged in in
the correct area of my template.

Well, I'm doing exactly that and it works just fine. This is a rough
outline of the flow:

GET <login page> (form with user and password fields)
POST <login page>

validate user+password, save in session
set().
redirect with 303 to <welcome page>

GET <welcome page>

Cat, the other other white meat

The question is, why aren't you using a session variable instead of
? That's one of the greatest features of PHP.

If you're able to use instead of sessions, and the size of the
data you're storing is fairly small, it's always better to use
. Sessions complicate scalability.

Ben: The *only* restriction around use of set is that there
cannot be any *output* before it. You can have as much code as you
want as long as it doesn't output anything. If your script outputs
content before your business logic is done then (IMHO) it's wrong and
needs to be rewritten anyway, regardless of the need to set a .

Hi,

My problem was a headers already sent error, which I fixed by redirecting
the form POST to a seperate file instead of the same login.php. Thanks for
all your !
