wp-ajax

WP Ajax with OOP

the WpAjax class can be extended, every method that is public and not magic will automatically be added to its own wp_admin hook. So for example:

// Method helloWorld will be added to hook: "wp_ajax_helloWorld" and optionally "wp_ajax_nopriv_helloWorld"
public function helloWord()
    {
        return wp_send_json("hello world");
    }

Nopriv is added by default but can be set false.
