sessions problems :/

i'm sorry if the solution to this problem was posted here before, but if it was i couldn't find it. i have an app that it's basically like this: index.php: $app = new App; $app->start(); in class app: function start() { (....) session_start(); if($need_auth) { global $auth; /* another class */ if(!isset($auth)) { $auth = new auth; session_register("auth"); } $auth->start(); } (....) } my question is, the auth class get's registered, and the auth array inside the auth class ($auth->auth[]) get his values recorded on the first attempt, but, if the user tries again, it doesn't refresh the session data, oh i'm using my session functions to write them on a mysql db, i've been debugging, and i can see all the queries that the session stores in the db through syslog, and for instance in $auth->start() if i change any variable like $this->auth["username"]=$username; the data field passed to my session_write() still has the first value not $username instead. another question is, at what time of the script does php call my session_write function to update the registered session?! thanks all -- Rui Barreiros Software Developer WEBSOLUT - Soluções Internet Emailto: rui@websolut.net Personal Info: http://websolut.net/people/rui.html As informações contidas neste email são confidenciais e destinam-se apenas à(s) pessoa(s) a quem foi enviado: http://websolut.net/confidencialidade-responsabilidade.html
