超出了代码点火器分页链接

Question

我的网站上有此分页。 我的问题是下面的链接过多。 例如，它转到页面228，并且那里不再有数据。

这是我下面的控制器代码

 public function index(){
    $this->data['title'] = 'Programs | Spring Rain Global Consultancy Inc';
    $this->data['active_menu'] = 'programs';
    $this->data['active_link'] = 'program_menu';

    $config = array();
    $config['base_url'] = base_url(). "programs/index";
    $config['total_rows'] = $this->am->record_count();
    $config['per_page'] = 12;
    $config['uri_segment'] = 3;
    $choice = $config['total_rows'] / $config['per_page'];
    $total_rows = $config['total_rows'] = $this->am->record_count();
    $config['num_links'] = round($choice);

    $this->pagination->initialize($config);
    $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
    $this->data['fecth_activities'] = $this->am->getAllActivities($config['per_page'], $page);
    $this->data['links'] = $this->pagination->create_links();
    //echo "<pre>";
    //print_r($this->data['links']);
    //echo "</pre>";

    $this->load->view('pages/header', $this->data);
    $this->load->view('templates/programs', $this->data);
    $this->load->view('pages/footer');
    $this->load->view('pages/footer_below');
  }

这是我的下面的模型

class Activities_model extends CI_Model{
  public function record_count(){
    return $this->db->count_all('seminars');
  }

  public function getAllActivities($start, $limit){
    return $this->db->limit($start, $limit)
                    ->select('seminars.id,
                        seminars.category, 
                        seminars.thumb, 
                        seminars_category.id,
                        seminars_category.category,
                        seminars_category.url,
                        seminars_category.date,
                        seminars_category.abvr'
                      )
                    ->from('seminars')
                    ->join('seminars_category', 'seminars_category.id = seminars.category')
                    ->where('seminars.id  =', 1)
                    ->or_where('seminars.id =', 7)
                    ->or_where('seminars.id =', 12)
                    ->or_where('seminars.id =', 20)
                    ->or_where('seminars.id =', 24)
                    ->or_where('seminars.id =', 29)
                    ->or_where('seminars.id =', 77)
                    ->or_where('seminars.id =', 84)
                    ->or_where('seminars.id =', 103)
                    ->or_where('seminars.id =', 157)
                    ->or_where('seminars.id =', 187)
                    ->or_where('seminars.id =', 234)
                    ->or_where('seminars.id =', 241)
                    ->or_where('seminars.id =', 308)
                    ->or_where('seminars.id =', 314)
                    ->or_where('seminars.id =', 390)
                    ->or_where('seminars.id =', 407)
                    ->or_where('seminars.id =', 414)
                    ->or_where('seminars.id =', 429)
                    ->or_where('seminars.id =', 455)
                    ->or_where('seminars.id =', 462)
                    ->or_where('seminars.id =', 511)
                    ->or_where('seminars.id =', 537)
                    ->or_where('seminars.id =', 573)
                    ->or_where('seminars.id =', 591)
                    ->or_where('seminars.id =', 641)
                    ->order_by('seminars_category.date', 'DESC')
                    ->get()->result_object();
    $query = $this->db->get('seminars');
    if($query->num_rows > 0){
      foreach($query->result() as $row){
        $data[] = $row;
      }
      return $data;
    }
    return false;

  }

}

这个东西有效，但只有下面的链接超过了228。

尝试这个，

class Activities_model extends CI_Model {

    public function record_count() {

        $this->db->where('seminars.id  =', 1)
                        ->or_where('seminars.id =', 7)
                        ->or_where('seminars.id =', 12)
                        ->or_where('seminars.id =', 20)
                        ->or_where('seminars.id =', 24)

您正在对数据库中的所有元素进行计数……在record_count函数的条件下，它可能会解决您的问题
