Shaun,
For what its worth, I experienced probs with destroying sessions until I added
another page. On the page in question, I called the 'logout' function and
redirected to that page:
[logout.php]
<?php session_start(); ob_start(); session_destroy();
header("location: http://your_site.back_to_page_that_is not_logged in.php");
?>
Note that I used an absolute url -- it seems to make a difference. [Btw, I
note that you use double quotes for $_SESSION['orderinfo'] -- just wondering
. . . .
HTh,
Andre
