I experienced the same warning when I use the header() function after
output-ing some text e.g.
echo("<html>");
header("Content-Type: text/html");
Try to check if you have the same situation.

From the manual at
<http://us2.php.net/manual/en/function.sessio n-start.php>
"If you are using cookie-based sessions, you must call session_start()
before anything is outputted to the browser."
You can output absolutely nothing before the call to session_start - no
DOCTYPE, no tags, not even any white space.

Well, the obvious answer is somewhere in your validation code you're
outputting something. Possibly white space, error message or something.
You should also have a message indicating where the output was started
(file and line).
But I'm sorry, I can't be of more help. I can't see your code from this
side of your screen.

are you trying to send the session_start() function again in your
include file?

I am pretty new to php but why couldn't you use output
buffering...... ..
ob_start(); at the very beginning of the php code, then at the end of
the php code use ob_end_flush(); ?

You could, and it would work, it's just bad programming. You hide an error
somewhere that shouldn't be there. Normal procedure is to do all actions
needed first, possibly with session-starting & conditional redirects, then
output. Just because something goes in the <headof an HTML document
doesn't mean you have to include/output that right away.

As we have establisted, this error is caused by sending information to
the browser before sending some header information such as a session
start.
if it works on your first visit but not on subsequesnt ones then you
must be sending some information to the browser before your header
info in that conditional statement.
remember:
NO OUTPUT BEFORE HEADERS
no line breaks,
no white space,
nothing.
(and definately no HTML!)
Dont have the session_start() function in your include file if you
call it from the initial script.
You could also check to see if the session is started already by using
the isset() construct.
hope this is of some help.

Of course it works perfectly on localhost, but when I upload it to the

verified, a new one is created and it's supposed to send them to the next
page.

$cNewCode = MakeCode();

Hi All
How can I produce an output to the browser and let the script continue
to work in the background, producing a later screen output?
Example:
Trigger a database search so that the user immediately sees a
"...searching..." screen while the script actually searches and later
on outputs the result.

Hi.
I am having a few header problems at the moment with a login page. I
don't have my headers at the top of the page where I've learned I need
to have them. However, I also know I'm supposed to have the
session_start(); at the top of the page as well. So when you have two
things that need to be the first which do you put first? And if I put
one before the other will that cause problems?
