pagination with codeigniter, other then index function - php

Question

I have set rout as
$route['dog/(:any)'] = "dog/index/$1"; /// for single dog info
$route['dog/list'] = "dog/listing"; /// for dog list, display all dogs.
$route['dog/list/(:num)'] = "dog/listing/$1"; /// for pagination
single dog url is like dog/dogName-4.html
my controller is as
public function index()
{
$dogInfo = $this->uri->segment(2);
if ($dogInfo != "")
{
$dogDetails = explode('-', $dogInfo);
$this->load->view('common/header',$header);
$this->load->view('dog/dog_info', $content);
$this->load->view('common/footer', $footer);
}
else
redirect('welcome', 'location', 301);
}
public function listing()
{
$this->load->library("pagination");
$breed = $this->input->get('breed');
$gender = $this->input->get('gender');
$state = $this->input->get('state');
$seller = $this->input->get('seller');
$config = array();
$config["base_url"] = base_url() . "dog/list/";
$config["total_rows"] = $this->dogs->get_dog_list_count($breed, $gender, $state, $seller);
$config["per_page"] = 5;
$config["uri_segment"] = 2;
$config['use_page_numbers'] = TRUE;
$this->pagination->initialize($config);
$page = ($this->uri->segment(2)) ? $this->uri->segment(2) : 0;
$content['details'] = $this->dogs->get_dog_list($config["per_page"], $page,$breed, $gender, $state, $seller);
$content['paginatonLinks'] = $this->pagination->create_links();
$content['total_dogs'] = $config['total_rows'];
$content['cur_page'] = $page + 1;
$content['total_pages'] = ceil($config["total_rows"] / $config["per_page"]);
$this->load->view('common/header');
$this->load->view('dog/dog_list', $content);
$this->load->view('common/footer', $footer);
}
The controller's index function is to display information about one dog, and listing function is for all the dogs,
I have to set pagination for listing function i did set all the required variables for pagination, pagination displaying the result as well
Found [134] Ads :: Page 1 of 27 1 2 3 > Last ›
but when i click on the pagination 1 2 3 else on page it brings me to the index page.
I need to be on the listing function of the controller. please any one help me.
here is the updated code
the rout code is
$route['dog/list'] = "dog/listing";
$route['dog/list/(:num)'] = "dog/listing/$1";
$route['dog/(:any)'] = "dog/index/$1";
and here is the updated controller code
$config = array();
$config["base_url"] = base_url() . "dog/list/";
$config['suffix'] = '?'.http_build_query($_GET, '', "&");
$config["total_rows"] = $this->dogs->get_dog_list_count($breed, $gender, $state, $seller);
$config["uri_segment"] = 3;
$config["per_page"] = 5;
$config['use_page_numbers'] = TRUE;
$config['full_tag_open'] = '<div class="pagination">';
$config['full_tag_close'] = '</div>';
$config['cur_tag_open'] = '<a href="#" class="page_selected">';
$config['cur_tag_close'] = '</a>';
$this->pagination->initialize($config);
$page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
$this->load->model('DogsListing_model', 'dogs');
$this->load->model('Breed_model', 'breeds');
$content['breeds'] = $this->breeds->get_all_id_title();
$content['details'] = $this->dogs->get_dog_list($config["per_page"], $page,$breed, $gender, $state, $seller);
$content['search'] = array('breed' => $breed, 'gender' => $gender, 'state' => $state, 'seller' => $seller);
$content['paginatonLinks'] = $this->pagination->create_links();
$content['total_dogs'] = $config['total_rows'];
$content['cur_page'] = $page + 1;
$content['total_pages'] = ceil($config["total_rows"] / $config["per_page"]);

Answer 1

i have found the solution of my question
first i have use $this->uri->segment(3) and $config["uri_segment"] = 3; i was using a wrong uri->segment for pagination. this solve my problem related to pagination.
my next part is i have to set variables for seller or search results with the pagination. for example i have the url doglist.html/?seller=29 i need to embed pagination with this pagination. so that the result will be like dog/list/3?breed=&gender=female&state=&submit2=Fetch i have solve this issue with this line of code $config['suffix'] = '?'.http_build_query($_GET, '', "&"); now my pagination with variables works fine.
Thanks to #jtheman and #Venkat, but mostly #jtheman for their contributings.
