如何使用产品类别编码器显示分页

嗨，我是一个新的编码器，我有编码的问题，我试图搜索谷歌和youtube，但我不能这样做，谁可以帮助我，请这是我的代码模型:

<?php
class Product_model extends CI_Model {

    function get_product($category="") {
        $this->db->select('*');
        $this->db->from('product');
        if($category) {
            $this->db->where('category',$category);
        }
        $query = $this->db->get();
        return $query->result();
    }

    function get_total($category="") {
        $this->db->select('count(*) AS num_row');
        $this->db->from('product');
        if($category) {
            $this->db->where('category',$category);
        }
        $this->db->limit(1);
        $query = $this->db->get();
        return $query->row()->num_row;
    }
}

和我的控制器代码:

public function __construct()
    {
        parent::__construct();
        $this->load->model('product_model','product');
    }
public function menu()
    {
        $data = array();
        $data['burger'] = $this->product->get_product('burger');
        $total_burger = $this->product->get_total('burger');
        $limit_burger = 1;
        $link_burger = 'http://localhost/mbl/site/menu/burger';
        $data['pagination_burger'] = $this->pagination($total_burger,$limit_burger,$link_burger);
        $this->load->view('header_view');
        $this->load->view('nav_view');
        $this->load->view('content_view');
        $this->load->view('content_left_view',$data);
        $this->load->view('content_right_view');
        $this->load->view('footer_view');
    }

    private function pagination($total ,$per_page ,$link) {
        $config['base_url'] = $link;
        $config['total_rows'] = $total;
        $config['per_page'] = $per_page;
        $config['page_query_string'] = TRUE;
        $this->pagination->initialize($config);
        return $this->pagination->create_links();
    }

和我的观点:

<h1>Burger</h1>
<ul>
    <?php foreach($burger as $val) { ?>
        <li><?php echo $val->title; ?></li>
    <?php } ?>
</ul>
<?php echo $pagination_burger; ?>
