RE: [PHP] Help! Can't set cookie or redirect!!!
OK...if your error says you have output, then you have output. It's not
lying to you. Your error was this:
> > > Warning: Cannot add header information - headers already sent by

Ok, that tells you that the "output started at ... /process.php:5", that
means line 5, which is phpinfo(), which causes output to the browser...
Lose that line...

Re: [PHP] Help! Can't set cookie or redirect!!!
Phil,
You are sending output somewhere prior to the following line:
header("Location: " . $HTTP_POST_VARS["refURL"]);
Basically, as soon as you output anything, PHP has to assume you are
finished manipulating headers.
Output can be anything from a space, newline, or HTML. It is not your
setcookie() function but something that happens prior to that. Remember
that everything not in PHP mode is considered output.

Ok thanx.. yeah I knew that you can set a cookie before anything is set to
the browser, however, if you view my code, nothing is sent as output before
the cookie is set.

RE: [PHP] Help! Can't set cookie or redirect!!!
You can only set a cookie before any output is send to the browser. A
newline, space, or , etc, is output to the browser. Redesign your
code so the cookie is set before any output or use output buffering.
