galvin Posted May 25, 2009 Share Posted May 25, 2009 In the body tag of my main page, I have... <body "onunload='wipeoutanswers()' > This is the AJAX function called wipeoutanswers()... function wipeoutanswers() { var xmlHttp; try { // Firefox, Opera 8.0+, Safari xmlHttp=new XMLHttpRequest(); } catch (e) { // Internet Explorer try { xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { xmlHttp=new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) { alert("Your browser does not support AJAX!"); xmlHttp=null; } } } if (xmlHttp !== null) { xmlHttp.onreadystatechange=function() { if(xmlHttp.readyState==4 && xmlHttp.status==200) { } } xmlHttp.open("GET","includes/wipeoutanswers.php", true); xmlHttp.send(null); } } And this is the very simple wipeoutanswers.php file... <?php require_once("session.php"); require_once("connection.php"); if (isset($_SESSION['answer0']){ unset($_SESSION['answer0']); } echo "we're getting something (this is just for testing purposes)"; ?> Maybe this isn't enough for someone to find what's wrong, but when I leave the main page, the onunload function seems to be running, but the $_SESSION['answer0'] variable (which is definitely set) is NOT getting unset. If anyone can see anything that might be causing a problem, let me know.
