Use of CI framework paging class (1)

First, query the database to determine how many pieces of data there are

$this->load->model('test_model');
$user=$this->test_model->user_select_all();
$pageall=count($user);//总条数
$pagenum=20;//每页显示的条数

Secondly, configure config

$config['total_rows']=$pageall;
$config['per_page']=$pagenum;
$config['num_links']=3;//定义当前页面的前后各有几个数字链接
$config['base_url']="
http://localhost/CodeIgniter_2.1.3/index.php/pages/pagelist/
";
$config['use_page_numbers']=true;//URL中的数字显示第几页，否则，显示到达第几条

##Finally, load the paging class and call

$this->load->library("pagination");//载入
$this->pagination->initialize($config);//初始化配置
echo $this->pagination->create_links();//显示<1 2 3 4.....>这样的页数选择
echo "
";
$id=$id?$id:1;
$start=($id-1)*$pagenum;
$list=$this->test_model->user_select_limit($start,$pagenum);//每一页的内容
var_dump($list);
