Hi Philip,
You'll probably want to move your session handling code to the
top of the main entry point of your application, rather than
starting it in a sub-page. This way all subpages get the benefit
of being able to use the session data. Even if not strictly
necessary, the option is there in the event you add features
later on that require sessions throughout the application.
A possible alternative is to use output buffering, which allows
you to start a session even after output has been sent. Though
this is more likely a kludge rather than a good solution to the
problem.

Subject: [PHP-DB] HTTP header information
Hi all.
I am running a website to where a user needs to login to authenticate
themselves to perform certain tasks. So a user logs in, and I start a
session (in PHP, of course). Well, the catch is, I am doing this all
from one page, 'viewer.php', and I just tack on the specific view/page
that I want them to see, depending on the link selected on that page.
Meaning, they click on the 'submit problem' link and it goes to
'viewer.php?type=submitproblem'.
The problem comes whenever I load the view 'submitproblem' and I start
a session with session_start(), which carries over the variable to tell
whether or not the user is logged in. If they have not logged in
whenever they click on 'submitproblem' then it will redirect them to
'viewer.php?type=login'. So I log in, and then go to 'submitproblem'.
This is where I get the error: Warning: session_start(): Cannot send
session cookie - headers already sent. Essentially, I understand why
this is occurring, but is there an easy way to get around it without
creating a new page, such as 'submitproblem.php' instead of
'viewer.php?type=submitproblem'???
Thanks a bunch
~Philip
