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. -Stuart

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.
