Re: setting session variables via a form

[".ma" <grillen@abendstille.at>]

hi!

i know that it sends everything to itself if you omitt the 
action-attribute, but it isn't propper html strict anymore... (ok - 
thats not a big problem *g*)

maybe it helps if you put the testing in a place of the script where 
there was no output yet (also no whitespaces)? at least this is a 
requirement for session_start(). probably similar things have to be 
considerd vor $_SESSION['foo'] = 'bar';
