maybe I can save you some time. If you used name="id", $_POST['id'] will
contain your selected value or nothing at all. you can try using isempty()
on it and see if that works.
if your select element were a multiple-select, then you should specify
select's name as id[] which signals to PHP to return an array of values.
then you would
foreach ($_POST['id'] as $val) {
do something with $val
}
