sorting - code igniter pagination with sort options -

-

i'm not sure if i'm ask possible or not.. i'm thinking not thought ask anyways.

is there way reset pagination?

i've got page has pagination , sort option on it. works fine when 1 of sort options changed send user first page.

(i'm pretty sure way i'm doing isn't @ best way result want if have suggestions improvements please feel free.)

        $array =  explode ("_",$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 pagination  $config['full_tag_open'] = '<div id="pagination" style= "clear:both;">';  $config['full_tag_close'] = '</div>';   //initialise pagination  $this->pagination->initialize($config);

you may keep default sorting in controller not show in url.so sorting not first page.

a sample

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'); }
