$this->load->model("article_model","art");
//载入分页类
$this->load->library('pagination');
$perPage = 2;

//配置项设置
$config['base_url'] = site_url('admin/article/index');
$config['total_rows'] = $this->db->count_all_results('hd_article');
$config['per_page'] = $perPage;
$config['uri_segment'] = 4;
$config['first_link'] = '第一页';
$config['prev_link'] = '上一页';
$config['next_link'] = '下一页';
$config['last_link'] = '最后一页';

$this->pagination->initialize($config);
$data['links'] = $this->pagination->create_links();

$offset = $this->uri->segment(4);    //偏移位置

$this->db->limit($perPage,$offset);   ／／进行数据库中的分页数据
