Subject:   Form submission with hidden element

You mentioned: testing for the presence of a hidden element avoids problems that can result from browsers' varying behaviors when a user submits a form by pressing the Enter key instead of clicking a submit button.
Could you elaborate on the problems that result when a user presses the enter key versus clicking the submit button?
I have generally just tested for the value of the submit button within my scripts instead of having to manage another form element (e.g. if (isset($_POST['submit_button_value'])) {process form} ). Is this not as good a method? Any thoughts would be appreciated.
Thanks.
