Just as a semi-educated guess, it sounds like PHP is inserting a field that
contains the PHP session ID.  The only reason I can think of that it would
do this is that the site is configured to use URL rewriting to propagate
session IDs, which would be a setting in the INI (session.use_cookies tells
the server whether to use cookies or to rewrite URLs, and
session.use_trans_sid tells it whether to automatically rewrite URLs or make
each page do it explicitly).  I would check the INI and see what those
settings are - it would not surprise me if that was the problem.  If so, you
can disable session.use_trans_sid to keep the form input from appearing,
though that will break sessions unless you manually rewrite URLs etc to
include the session id.
