var_dump($sql);
$items = $wpdb->get_results($sql);
} else {
$items = $wpdb->get_results('SELECT * FROM ' . $wpdb->prefix . 'haozhuti_guestbook2 ORDER BY ' . $args['orderby'] . ' ' . $args['order'] . ' LIMIT ' . $args['offset'] . ', ' . $args['number']);
}

add_action("load-$hook", array($this, 'screen_option'));
4,在Hzt_Order_Management_Admin_Menu的类中添加如下方法
