WP_Customize_Manager::doing_ajax() WordPress Method

The WP_Customize_Manager::doing_ajax() method is used to determine whether the current request is for an Ajax call. This can be useful for checking if you need to do any special handling for Ajax requests. For example, you might want to disable certain caching mechanisms for Ajax requests.

WP_Customize_Manager::doing_ajax( string|null $action = null ) #

	public function doing_ajax( $action = null ) {
		if ( ! wp_doing_ajax() ) {
			return false;
		}

		if ( ! $action ) {
			return true;
		} else {
			/*
			 * Note: we can't just use doing_action( "wp_ajax_{$action}" ) because we need
			 * to check before admin-ajax.php gets to that point.
			 */
			return isset( $_REQUEST['action'] ) && wp_unslash( $_REQUEST['action'] ) === $action;
		}
	}
