We have a similar need and want to include on each badge the attendees role, membership level, and a short code for their fee level. We have been doing an Excel export and mail merge, which is not too bad for advance registrations, but unworkable for on-site registrations. We would also like to be able to include static text fields and concatenate fields such as city and state. I looked for the PHP pages for badge formatting and did not find which files would need to be modified-- has anyone had success with customizing this?
