adhbvklwqdbviabjiawdnbij Posted August 14, 2011 Share Posted August 14, 2011 I want to show de Logout button when $_SESSION['SESS_CATEGORY'] is 3 but i get a error: Parse error: syntax error, unexpected '<' in /home/ibn/public_html/escola/home.php on line 17 <?php if(trim($_SESSION['SESS_CATEGORY']) == '3') { echo <a href="actions/logout.php">Logout</a>; exit(); } ?> Quote Link to comment Share on other sites More sharing options...
MasterACE14 Posted August 14, 2011 Share Posted August 14, 2011 change this: echo <a href="actions/logout.php">Logout</a>; to this: echo "<a href=\"actions/logout.php\">Logout</a>"; Need to remember to wrap those quotes around an echo.

Clarkeez Posted August 14, 2011 Share Posted August 14, 2011 Hi, adhbvklwqdbviabjiawdnbij < lol "Warning: Cannot modify header information - headers already sent" This is because session_start() and header("location: ../index.php"); are both sending header information. Now, header information can only be send once, and must be sent BEFORE anything else is executed or sent to the browser.. Hence why your header() function is causing this error.. I personally use <meta http-equiv="refresh" content="0;URL=YOURURLHERE"/> as an alternative. But be careful, this might not be XHTML valid, but we will work.

MasterACE14 Posted August 14, 2011 Share Posted August 14, 2011 I think you may be using the wrong function... <?php include("../index.php"); ?> I believe that's what you want. Quote Link to comment Share on other sites More sharing options...
