I'm trying to create a profile to be used as a form, but rather than having the user populate certain fields, have the form populate them automatically. An example of what I'm trying to do:
The profile form is only presented to people that are registering as guests, therefore I want to pre-select the Membership Type as
Guest rather than allowing the user to select the membership type. In fact, I don't even want the user to see the membership type field.
I'm running CiviCRM 4.7.6 on WordPress 4.4.2.
