How about you name your checkboxes as: name="setting[xx]" where xx is from your $vars array above. You'll end up with name="setting[noPlatform]" value="1" name="setting[noPrice]" value="1" etc... Now, you'll have $_POST['setting'] that'll contain the checked boxes. To put those in session: $_SESSION['setting'] = $_POST['setting']; To see which boxes were checked... $checked = array_keys($_POST['setting']); or $checked = array_keys($_SESSION['setting']); $checked now an array similar to your $vars above but it only contains the values that were checked. To find out which checkboxes were NOT checked, you could use: $not_checked = array_diff($vars,$checked); Easy, eh??
