I try to avoid the use of hidden form elements as much as possible,
especially for tracking whether a user has submitted a form or not...

I use name="submit" for the submit button instead, that will pass the
value of the submit button to the action script.

above all i use a template engine, smarty to take care of the
presentation for me(like deciding whether to show the form and/or a
success/failure message)

That only works if the user clicks on that submit button. If the user
hits the enter key in a text input, the form is submitted but the submit input variable is not set. That is why an hidden input is a safer solution.

If you need the button to be *clicked*...

<form onsubmit="$('submitButton').fireEvent('click');" ...>

Or something along those lines.
