Session ID Problem

[Jonathan]

I use a Session ID to remember a user that's logged in on my site,
which works pretty well for the most part, because index.html sends
them to a page (index0.php) that starts the session and then sends
them on to index.php. However, this means that if someone goes
straight to one of the pages on my site that requires a Session ID to
allow them access to something, the page returns error strings at the
top, although it does proceed to display the rest of the page (so at
least it kind of works). I've tried just putting the session_start() ;
code right into the same page, but it then returns an error and won't
display the page at all. Is there any good way to start a session
within the same page (HTML or PHP) that I plan to locate the variable?
And just out out of curiousity, why doesn't it work to simply place
the session_start() ; code earlier in the code than the code to catch
the session variable?

Thanks in advance,

Jonathan

It returns "an error"! _What_ error does it return?

Re: Session ID Problem

Well, the easiest way is to turn on auto-session.

Calling session_start() doesn't cause any session variables to become
defined. Presumably that's the warning message that you're getting.

First of all, avoid using an .html file because every time it is
called, the session for the user calling that page is lost.
Use only .php files and put session_start() early in the script,
before any output is produced because the session must be started
before the headers are sent (when producing any kind of output the
headers are automatically sent). Another possible cause of error while
using session_start() could arise if you are using windows and haven't
defined a directory for the sessions.

If you need any further help, please be a little more specific on you
script and the exact errors it produces.

Re: Session ID Problem

I had the same prob until i included this on each page.

<?
$memberid = $_SESSION['pp_userid'];

if (empty($memberi d)) {
echo "<p><b>Unauthor ised User</b></p>";
echo "Please click <a href=\"member.p hp\">here</a> to login";
die;
}
?>
