Question

当我在第一页时，我点击分页链接（2），链接（3），链接（4）页面分页链接无效。

  <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

    class Pagination extends CI_Controller
    {
    public function __construct() {
    parent:: __construct();

    $this->load->helper("url");
    $this->load->model("Countries_Model");
    $this->load->library("pagination");
    }   
    public function index() {
    $config = array();
    $config["base_url"] = base_url() . "pagination";
    $config["total_rows"] = $this->Countries_Model->record_count();
    $config["per_page"] = 10;
    $config["uri_segment"] = 3;
    $choice = $config["total_rows"] / $config["per_page"];
    $config["num_links"] = round($choice);
    $config['use_page_numbers'] = TRUE;
    $config['page_query_string'] = TRUE;    
    $config['prev_link'] =TRUE; 


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

    $page = ($this->uri->segment(2))? $this->uri->segment(2) : 0;
    $data["results"] = $this->Countries_Model
    ->get_countries($config["per_page"], $page);
    $data["links"] = $this->pagination->create_links();

    $this->load->view("pagination", $data);
    }
    }   ?>

Answer 1

更改此行：

$config["base_url"] = base_url() . "pagination";

到

$config["base_url"] = base_url("pagination/index");

Answer 2

我想这个方法从数据库中获取数据：

 $data["results"] = $this->Countries_Model
->get_countries($config["per_page"], $page);

你还需要传递一个偏移量（$ offset是你的情况下的第4段），

控制器中的

 public function index($offset = 0) {
  .....
 $this->Countries_Model
->get_countries($config["per_page"], $page,$offset);
 }

在您的模型中

  get_countries($per_page, $page,$offset){
 ......
  $this->db->get('yourtable',$per_page, $offset);
 }

分页链接对我不起作用
