I would like save to log file any action of any user: new event , edit , deleting. I can code php, but i need some help where in scheduler code i must do it.
Example:
added event 51: system date and hour, “data event (text, time…)”
modified event 51: …
deleted event 53…
etc.
I need it because our calendar is public to certain users (group of friends) and sometimes they are deleting/editing by error. With a log system i can restore events.
