run_action()

This method is responsible for running whatever action should trigger the functions that need to run inside the asynchronous request. The convention is to use "wp_async_$this->action", but that is up to the implementation.

protected function run_action() {
	$post_id = $_POST['post_id'];
	$post = get_post( $post_id );
	if ( $post ) {
		// Assuming $this->action is 'save_post'
		do_action( "wp_async_$this->action", $post->ID, $post );
	}
}
