Hello, my english is poor. I have problem with swfupload session. I set session_id in form variable, then it goes with post. Ok it's working but when i get this post and set session by session_id($_POST["session_id"]) I have good session_id, beacouse i checked this, but i dont't have variables in $_SESSION table. In my home computer this works fine, on server not. Maybe i should check some settings of php sessions? Sorry for my english.
