I want to add extra field values based on the results of another form. So, for example, I have a group size which is set in another form. Let's say the group size is 3. On the form we're discussing it would dynamically show 3 sets of first name and last name fields. I'm not sure of how big the group will be, so I can't just use conditional fields. I've gotten this to work by adding a parameter on the end of the URL, but how can I get the information from the extra fields to be saved in the database / sent in the admin email ??? Should I use ninja_forms_process ?? How do I make ninja forms recognize / save these extra fields I added ?
