Let’s say you want to get some input from your visitor and then store in in session variables, here’s the code:

<?
session_start();
if ($_POST['field_that_was_posted']) {
session_unregister(”session_field_name”);
$session_field_name = $_POST['field_that_was_posted'];
session_register(”session_field_name “);
}
?>

now you can call your session variable by using this string

<? echo $_SESSION['session_field_name']; ?>

just make sure you have session_start(); stacked on top of all the calls.

When you want to kill the session just call session_destroy();
