带有排序选项的代码点火器分页

Question

我不确定我要问的是否可能。我想可能不会，但我想无论如何我都会问。

有什么办法可以重置分页吗？

我有一个页面，上面有分页和排序选项。一切正常，但是当其中一个排序选项更改时，我想将用户发送回第一页。

（我很确定我这样做的方式根本不是获得我想要的结果的最佳方式，所以如果您有任何改进建议，请随时提出。）

        $array =  explode ("_",$this->uri->segment(4));

        if(count($array) > 1){
            $search_id = $array[1];
            $start = $this->uri->segment(5);
            $uri_segment = 5;
        }else{
            $start = $this->uri->segment(4);
            $uri_segment = 4;
            $search_id = null;
        }
$config['per_page'] = $this->settings['PRODUCTS_PER_PAGE'];

$config['total_rows'] = $this->categories_model->get_num_rows($cat_id , $search_type, $search_data);

$query = $this->categories_model->get_category_pages($cat_id, $new_limit, $new_sort, $search_id, $start, $this->settings['CATEGORY_ORDER'], $search_type, $search_data,  $config['total_rows']))

$config['base_url'] = base_url() . 'index.php/categories/view/' . $cat_id ."/" . $search_string ;

 $config['uri_segment'] = $uri_segment;

 //Congig settings for pagination
 $config['full_tag_open'] = '<div id="pagination" style= "clear:both;">';
 $config['full_tag_close'] = '</div>';

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

您可以在控制器中保留默认排序，该排序不会显示在 url 中。因此排序不会返回到第一页。

一个样本

class Post extends Jewelery_Controller {

public function __construct() {
  parent::__construct();
  $this->load->model('Prime_model');
 }

  public function index($ordr_by = 'post_title', $sortr = 'ASC') {

  if ($this->uri->segment(6)) {
     $data['segment'] = $this->uri->segment(6);
  } else {
     $data['segment'] = 0;
  }

  if ($this->uri->segment(4)) {
     $ordr_by = $this->uri->segment(4);
  }

  if ($this->uri->segment(5)) {
     $sortr = $this->uri->segment(5);
  }

  $data['title'] = 'All Posts';
  $this->load->library('pagination');
  $config['base_url'] = base_url() . 'admin/post/index/' . $ordr_by . '/' . $sortr;
  $config['full_tag_open'] = '<div class="pagination"><ul>';
  $config['full_tag_close'] = '</ul></div>';
  $config['cur_tag_open'] = '<li class="active"><a href="">';
  $config['cur_tag_close'] = '</a></li>';
  $config['prev_tag_open'] = '<li>';
  $config['prev_tag_close'] = '</li>';
  $config['next_tag_open'] = '<li>';
  $config['next_tag_close'] = '</li>';
  $config['num_tag_open'] = '<li>';
  $config['num_tag_close'] = '</li>';
  $config['uri_segment'] = 6;
  $config['total_rows'] = $this->db->get('jewel_posts')->num_rows();
  $config['per_page'] = 10;
  $this->pagination->initialize($config);


  $data['post_info'] = $this->Prime_model->master_join('jewel_posts', 'jewel_jewelry_type', 'jewel_posts.jewelry_type = jewel_jewelry_type.jewelry_type_id', 'left', FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, FALSE, $ordr_by, $sortr, $config['per_page'], $data['segment']);
  $this->load->view('admin/header', $data);
  $this->load->view('admin/post/index');
  $this->load->view('admin/footer');
}
