chigley Posted May 12, 2007 Share Posted May 12, 2007 Try uncommenting the session_start() lines as your code can't read the $_SESSION[] variables without it. Also, another error I just spotted: echo $_COOKIE['uid]; should be echo $_COOKIE['uid']; Link to comment https://forums.phpfreaks.com/topic/51045-_sessionsetcookies-problem/#findComment-251202 Share on other sites More sharing options...

chigley Posted May 12, 2007 Share Posted May 12, 2007 I'm confused as to what you're trying to do. Surely you realise that you can't read/write to $_SESSION[] variables without a session_start() line first, which in your snippet you have commented out.
