Description

This construct fires the specified event, which means it loops through the event registry lookup table and calls each registered callback one-by-one. The callbacks are pre-registered for this event using add_action.

Note: this construct is identical to do_action, except that all the arguments to be passed to the callbacks are wrapped into one array of arguments. Otherwise, the code is identical and it works the same.

Parameters

event_name

The name of the event (filter hook) to fire.

args

An array of arguments to pass to each registered callback.

Return Values

It does not return anything, which is the main difference between an action and filter event.
