Hey Jason,
Good question. Additional fields are a good way to go for sure. If you create an additional text field, you can then override the template for event details to remove it from where it currently displays and place it with the cost information instead.
Our Themer’s Guide has a lot more information on template overrides. The specific templates you are looking for are:
- additional-fields.php – located in /events-calendar-pro/src/views/pro/modules
- details.php – located in /the-events-calendar/src/views/modules/meta/
From there, you can either copy and paste the addition fields code from the first template into the second, or use the tribe_get_custom_field() function to call that specific additional field in the second template.
Cheers!
Geoff
