that works;
i personally prefer to initialize a variable then only set it if the
user input meets some
conditions; its called white-box validation.
$due_date = '';
if(isset($_POST['due_date'])) && !empty($POST['due_date'])) {
$due_date = trim($_POST['due_date']);
}
the more you know about what the contents of due_date are supposed to be, the
stronger you can make the check; for instance here, it sounds like it
should be a date
so you wouldnt allow, say 'somecrazySting', to pass the validation.
