obsidian Posted March 14, 2006 Share Posted March 14, 2006 you're missing your closing parenthesis on your if statement:[code]// change this:if (isset($_SESSION['username']) {// to this:if (isset($_SESSION['username'])) {[/code]btw, you'll get the same error on your second if statement, too.

redbullmarky Posted March 14, 2006 Share Posted March 14, 2006 change this:[code]if (unset($_SESSION['username']) {[/code]to this[code]if (!isset($_SESSION['username'])) {[/code][b]EDIT:[/b] ooops same time post again......in which case, the way obsidian suggested is much better for what you're after anywaycheers Quote Link to comment https://forums.phpfreaks.com/topic/4924-unexpected-in-session-code/#findComment-17352 Share on other sites More sharing options...

Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0[/quote]Hi from Germany,the first error message seems to be php.ini - config problem. you're using windows, the standard php.ini (\tmp) for session dir is no usable under windows. you have do create a directory and add this to your php.ini likesession.save_path = C:\Program Files\Apache Group\Apache2\sessionsThe second and third error message due to the first error message, this was an output and session_start() must be set before any screen output.Hope it will work,webwiese Quote Link to comment https://forums.phpfreaks.com/topic/4924-unexpected-in-session-code/#findComment-17362 Share on other sites More sharing options...
