wp_ajax_{$action} WordPress Action Hook
The wp_ajax_{$action} hook allows you to perform an action when an AJAX request is made to WordPress.
do_action( "wp_ajax_{$action}" ) #
Fires authenticated Ajax actions for logged-in users.
Description
The dynamic portion of the hook name, $action, refers to the name of the Ajax action callback being fired.
More Information
- This hook allows you to handle your custom AJAX endpoints. The
wp_ajax_hooks follows the format “wp_ajax_$action“, where$actionis the ‘action‘ field submitted toadmin-ajax.php. - This hook only fires for logged-in users. If your action only allows Ajax requests to come from users not logged-in, you need to instead use wp_ajax_nopriv_$action such as:
add_action( 'wp_ajax_nopriv_add_foobar', 'prefix_ajax_add_foobar' );. To allow both, you must register both hooks! - See also wp_ajax__requestaction
