we are looking for a difficult customization.
Add an new datefield under the birthday field in the contact form and show the name (like a birthday) in the calendar.
I have the following clues:
- database extension
- MVC (model view controler) of contact
- MVC (model view controler) of calendar
Did I forget anything?
Must I edit the upstream source code or can i customize it with my own module?
Thanks and best regards.
