This function is a form validation function, it will check all specified fields for values and validate email addresses
(email address field names MUST contain the word 'email' and non-email fields MUST NOT contain the word 'email')

Your form must contain a hidden field called 'required_fields' listing the field names seperated by a comma
and a hidden field called 'required_names' listing the 'nice' names of those fields on the same order
