About: Shows all calls to trigger_event
Piwigo has two type of triggers: one to notify of an event and one to allow modification of a particular variable. The triggers functions was named trigger_event() and trigger_action() witch is not a natural naming…
In 2.6 we added trigger_change() (alias of trigger_event) and trigger_notify() (alias of trigger_action).
In 2.7 the old functions will be removed.
