wp-includes/plugin.php: doing_action() | Retrieve the name of an action currently being processed. |
Retrieve the name of a filter currently being processed.
The function current_filter() only returns the most recent filter or action being executed. did_action() returns true once the action is initially processed.
This function allows detection for any filter currently being executed (despite not being the most recent filter to fire, in the case of hooks called from hook callbacks) to be verified.
(null|string) (Optional) Filter to check. Defaults to null, which checks if any filter is currently being run.
Default value: null
(bool) Whether the filter is currently in the stack.
File: wp-includes/plugin.php
function doing_filter( $filter = null ) { global $wp_current_filter; if ( null === $filter ) { return ! empty( $wp_current_filter ); } return in_array( $filter, $wp_current_filter, true ); }
