The What
Description
This construct returns the name of the event (action hook) that is being processed. It may not be the one that is currently calling its callbacks, as it is possible to have multiple events firing at the same time. If you want the current one, i.e. the one that is calling its callbacks right now, then use current_filter.
Parameters
event_name- optional The name of the event you want to check.
Return Values
If an event name is passed into the construct, then it returns true if that event is being processed.
If no event name is provided, then it returns an array of all the events that are being processed.
There’s a time to code and …. yup, that sums it up.
More coming soon…keep checking back.
