只是好奇——AJAX操作是否可以连接到wp 钩子
例如：
add_action( \'wp\', array( \'MyAjaxRegistrarClass\', \'ajax_registrar\' ) );

// MyAjaxRegistrarClass
class MyAjaxRegistrarClass{

    public static function ajax_registrar() {       
        MyAnotherClass::fn_register_ajax();
        //Call fn_register_ajax of other classes here
    }
}//Class Ends here

// MyAnotherClass
class MyAnotherClass {

    public static function fn_register_ajax() {     
        add_action( \'wp_ajax_testing_ajax\', array(__CLASS__, \'testing_ajax\' ) );
    }   

    public static function testing_ajax() {     
        echo \'Success!\'.__FUNCTION__.\' was called from \'.__CLASS__;     
        die();
    }   
}
