    Here are quick solutions:

    1. After your form has been saved or if it has an error, redirect them to the same page but with GET variables in the uri like process.php?action=save. Use header function for redirection.

    2. You also use cookies to save the IP of the person who submits the form and restrict him for certain period to be able to submit the form again.
