If you use this method then you'll completely ignore a form submission
if they've forgotten to enter a username. Detection and validation are
two distinct steps and should be treated as such.
I usually treat forms this way:
$action = isset($_POST['action']) ? $_POST['action'] : null;
and then deal with $action.
Dealing with $action means that I might clean/scrub it for storage in
MySQL, or use it to determine a course of processing, or any number
of other things.
The point is to check IF a $_POST has occurred, without triggering an
error if it hasn't, and to deal with the outcome either way.
