I want to develop a very simple Extension which :
- searches the current contact_id
- then verifies if he is recorded for a given event (event_id as a parameter)
- then, depending on the result, echoes a message or opens an URL.
I read that, to develop an extension, I first had to :
- install Civix,
- which requires installing first git and composer ... which seems very complicated to me for such a simple program.
Is there a way to write and upload directly the code in the Extension directory, whithout all these prerequisites ?
