I want to create a custom hidden field in the advanced tab. If this field ist selected, the form should automatically add userinformation to the form like: user_id = userId, user_email = user-mail, eventanmeldung = 1
I need it as a button, as there will be a couple of forms maintained by a content guy. He won’t be able to create each time 3 fields with populated input manually.
Thanks for your help.
