Codeigniter 分页函数初始化不工作

当我试图在codeigniter中创建分页时。我收到一个调用未定义函数初始化为空的错误

class Admin_Controller extends CI_Controller
 {
function __construct()
{
    parent::__construct();
    $this->load->model('admin_model');
$this->load->library('pagination');
}

function index()
{
    $this->load->view('registration');

}

  public function manage()
{
       //$this->session->set_userdata($active);
       $config = array();
       $config["base_url"] =   site_url('admin_controller/manage');
      $config["total_rows"] = $this->db->get('entries_new') ->num_rows();
      $config["per_page"] = 2;
      $config["uri_segment"] = 3;
      $config["num_links"] = 3;
      $config['prev_link'] = 'Previous';
      $config['next_link'] = 'Next';
      $config['last_link'] = 'Last';
      //echo "<pre>";die(print_r($config));

      $this->pagination->initialize($config);
       $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
      $data['pagination'] = $this->pagination->create_links();
    $data['ResAre']=$this->admin_model->get_data($config["per_page"],$page);
       $this->load->view('adminpage',$data);
}
 function register()
{
    if($this->input->post('register'))
    {
        $this->admin_model->insert_data();
        redirect(base_url('index.php/login_controller'));
    }
}

function update()
{
    if(isset($_REQUEST['editid']) && $_REQUEST['editid']!='' && $_REQUEST['editid']!=0)
        { 

      $data['ResAre']=$this->admin_model->update();
          $this->load->view('updatepage',$data);
}
   }

    function updated()
    {
      if(isset($_POST['update']))
        {

         $this->admin_model->updated();
         redirect(base_url('index.php/admin_controller/manage')); 

        }
}
function delete()
{
   if(isset($_REQUEST['deleteid']) && $_REQUEST['deleteid']!='' && $_REQUEST['deleteid']!=0)
        {
        // load model
         $this->admin_model->delete();
         redirect(base_url('index.php/admin_controller/manage')); 
         }
  }

 }

希望这对您有所帮助：

在您的模型中：

首先：在
admin\u model
中，您正在使用
CI\u Controller
扩展它，将其更改为
CI\u model

    $config = array();
    $config["base_url"] =   site_url('admin_controller/manage');
    $config["total_rows"] = $this->db->get('entries_new')->num_rows();
    $config["per_page"] = 2;
    $config["uri_segment"] = 3;
    $config["num_links"] = 3;
    $config['prev_link'] = 'Previous';
    $config['next_link'] = 'Next';
    $config['last_link'] = 'Last';

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

    $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
    /* pass offest and limit here if not passing*/
    $data["ResAre"] = $this->admin_model->get_data($config["per_page"],$page);

    $data["pagination"] = $this->pagination->create_links();
    $this->load->view('adminpage',$data);

第二：在
controller
和
model
中的
get_data（）
方法中设置限制和偏移量

你在哪里通过偏移和限制？实际上我忘了设置限制，现在我修正了偏移。但在错误仍然保持不变之后，请浏览一段代码，您在哪里准确地得到了错误以及错误是什么，请精确设置错误行号33，即
$this->pagination->initialize（$config）和错误\u处理程序显示致命错误：在C:\wamp\www\codeigniter\application\controllers\admin\u controller.php第33u行将模型扩展到CI\u控制器将其更改为CI\u模型查看我的更新答案
    $config = array();
    $config["base_url"] =   site_url('admin_controller/manage');
    $config["total_rows"] = $this->db->get('entries_new')->num_rows();
    $config["per_page"] = 2;
    $config["uri_segment"] = 3;
    $config["num_links"] = 3;
    $config['prev_link'] = 'Previous';
    $config['next_link'] = 'Next';
    $config['last_link'] = 'Last';

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

    $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
    /* pass offest and limit here if not passing*/
    $data["ResAre"] = $this->admin_model->get_data($config["per_page"],$page);

    $data["pagination"] = $this->pagination->create_links();
    $this->load->view('adminpage',$data);
