I have a login page which sends a variable to another page verifying if login is true (1) or false (0). I can echo $_SESSION['logon'] on page1 but just as I go to page2, my session seems to be dead and gives me * Notice: Undefined index: logon in * I have already fiddled with php.ini but to no avail. Register_globals = off by the way. I'm a rookie so I might have passed something wrong, didn't change the right parameter in php.ini, don't know.
Login Page:

And I'm sorry about any typo I may have sent.
You are using exit before echo and you need to check condition on pag2.php like this :
if(isset($_SESSION['logon']) && $_SESSION['logon'] != "") {
$logon=$_SESSION['logon'];
if($logon==0){
//header("Location: index.php");
echo $_SESSION['logon'];
exit();
}
}
