The SID will only be added automatically if -enable-trans-sid is set and
your browser has cookies switched off. When cookies are on the session id
is propagated using a cookie. So likewise the <?=SID?> constant will only
be expanded when cookies are switched off.
Anyway, yes you will have to add <?=SID?> to all your URL's if you want
people to be able to access it with cookies disabled. Plus you will need to
add a hidden field on all your forms i.e.
<INPUT TYPE="HIDDEN" NAME="TESTSESSID" VALUE="<?php echo session_id()?>"> so
that the session_id is propagated when ther form is submitted.
When you changed you session_name did you remember to call session_start
again.
session_name("TESTSESSID"); // session i want to use
session_start(); // start specified session.

Subject: [PHP] Sessions
I have been doing a few test pages trying to figure out how
sessions work.
The SID is not being automatically added to my urls so I assume
that means that php was not compiled with -enable-trans-sid (I'm
on a virtual server so I can't access php.ini)
So that means that I need to add <?=SID?> to all my urls,
correct?
Can I change the value of session_name() and still have the above
work for the new session name?
I tried it and the session_name was changed to the new value, but
then SID seemed to be empty after that. Is there something I am
missing or is that the way it is supposed to work?
