这篇文章主要介绍了CodeIgniter分页类pagination使用方法,结合实例形式简单分析了CodeIgniter框架中的分页类pagination基本的配置与使用技巧,需要的朋友可以参考下。

本文实例讲述了CodeIgniter分页类pagination使用方法，分享给大家供大家参考，具体如下：

controller控制器（application/controller/page.php文件）：

public function index()

{

    $this->load->model ( 'home_model' , '' , TRUE);

    $config= array();

    $config['per_page'] = $this->per_page; //每页显示的数据数

    $current_page    = intval($this->input->get_post('per_page',true)); //获取当前分页页码数

    //page还原

    if(0 == $current_page)

    {

      $current_page = 1;

    }

    $offset = ($current_page - 1 ) * $config['per_page']; //设置偏移量限定数据查询起始位置（从 $offset 条开始）

    $result = $this->home_model->index($offset,$config['per_page'],$order='id desc');

    $config['base_url']      = $this->config->item('base_url').'admin/home/index?';

    $config['first_link']     = $this->first_link;//首页

    $config['prev_link']     = $this->prev_link;//上一页

    $config['next_link']     = $this->next_link;//下一页

    $config['last_link']     = $this->last_link;//尾页

    $config['total_rows']     = $result['total'];//总条数

    $config['num_links'] = 3;//页码连接数

    $config['use_page_numbers']  = TRUE;

    $config['page_query_string'] = TRUE;

    $this->load->library('pagination');//加载ci pagination类

    $this->pagination->initialize($config);

    $result = array(

        'list' => $result['list'],

        'total'  => $result['total'],

        'current_page' => $current_page,

        'per_page' => $config['per_page'],

        'page'  => $this->pagination->create_links(),

    );

    $this->load->view ( 'admin/home' , $result );

}

model模型（application/model/home_model.php文件）：

public function index($offset,$num,$order='id desc')

{

    $query = $this->db->query( "SELECT Name_cn,Mall_type,create_time FROM smzdm_mall WHERE Is_deleted = 0 order by {$order} limit {$offset},{$num}");

    return array(

        'total' => $this->db->count_all('smzdm_mall',array('Is_deleted'=>'0')),

        'list' => $query->result(),

    );

}
