The default field set is:<\/p>\n\n
'title', 'first_name', 'last_name', 'email', 'telephone', 'submit'<\/p>\n\n
So if you simply use the shortcode with no attributes it will create a form with those fields, and with title, first_name\nlast_name and email as required fields, and with html5 enabled and the html5shiv enqued also.<\/p>\n\n
If you set form_type to 'subscribe' it adds a field for username and password, with password automatically having a confirm field as well, which is of course part of the in-built form validation. The user is added to WP as a subscriber and notifications are sent also.<\/p>\n\n
If you set 'contact' as the form_type attribute, then instead of username and password the plugin adds a text field for company, and a subscribe to newsletter checkbox. If they hit subscribe then they are added to Wp as a subscriber, with the first part of their email as username (numbers are appended if the name exists, and continue to be changed until unique name is found).<\/p>\n\n
The function that does all that field adding ends with a filter, as does the function that configures all the field settings such as type\/required etc for easy addition of custom field types.<\/p>\n\n
