application / classes / model / news.php

    public function get_latest_news() {
        $sql = 'SELECT * FROM `news_example` ORDER BY `id` DESC LIMIT  0, 10';
        return $this->_db->query(Database::SELECT, $sql, FALSE)
                         ->as_array();
    }

    public function validate_news($arr) {
        return Validate::factory($arr)

        $insert_id = DB::insert('news_example', array('title','post'))
            ->values(array($d['title'],$d['post']))
            ->execute();

        return $insert_id;
