class User extends CI_Controller {

    public function index(){ //        $this->db->join('comments', 'comments.id = blogs.id');
         $this->load->model('users');
         $data['base_url'] = base_url() .'dashboard/user/';
         $data['total_rows'] = $this->db->get('tbl_cpanel_user')->num_rows();
         $data['per_page'] = 3;
         $this->pagination->initialize($data); //        $data['pagination'] = $this->pagination->create_links();
         $data['results'] = $this->users->pagination($data['per_page'], $this->uri->segment(3));
         $this->load->view('dashboard/user',$data);

    }
}

defined('BASEPATH') OR exit('No direct script access allowed');
class Users extends CI_Model {

    //pagination functions
    public function pagination($limit, $offset){
         $this->db->select('tbl_cpanel_user.Name, tbl_cpanel_user.Email, tbl_cpanel_user.ContactNumber,
 tbl_cpanel_user.Address,tbl_cpanel_user.UserId,tbl_cpanel_area.AreaId,tbl_cpanel_area.Area');
         $this->db->from('tbl_cpanel_user');
         $this->db->join('tbl_cpanel_area', 'tbl_cpanel_user.AreaId = tbl_cpanel_area.AreaId');
         $this->db->limit($limit, $offset);
         $query = $this->db->get();enter code here
         if($query == true){
             return $query->result();
         }else{
             return false;
         }
     }
