php sessions... compatable?

Fritz

We just went live with a session based sollution - and some folks are crying that they just can't log in... - at this point I do believe them...

Does anyone know of os/browsers combos that just can't deal with PHP sessions?

Does php sessions NEED to set some sort of cookie ? like a php session cookie?

This is dependent on certain configuration options, namely "use_only_cookies" vs. "use_trans.sid" (something like that) in php.ini.

PHP generally sets a cookie with the session id number on the client. In the event you have a client not accepting cookies and "use only cookies" set, you could very easily have this type of problem.

With "trans" (-parent) session handling, if cookies fail, then PHP will automagically append the SID to the query string, IIRC.

What's phpinfo() tell you about your session settings?

I can turn sessions on and off ... but I don't have the option to do an off if ... or an only use sessions option... Perhaps I running an older version.

as dalecosp stated, run phpinfo() and see what version you have, also look down at the session information. Copy and paste it if you'd like so we can see what's up.

Have you tested session usage on yourself? Different users can have browser settings that only allow cookies to be set from the exact domain so if you try to set the session from www.example.com but then take them to abc.example.com, the cookie may not be readable anymore.

look at the session functions on php.net and check out session_set_cookie_params
