Getting the same data on pagination in Codeigniter - codeigniter

Question

I am getting the same data when I am clicking on the next button of pagination in CodeIgniter with the following code
public function view($slug){
$data['title']= $slug;
$data['description']= "None";
$postdatacount = $this->Constant_model->snippettagscount($slug);
$checktags= $this->Constant_model->gettags($slug);
if($checktags>0){
if ($postdatacount>0) {
$config = array();
$config["base_url"] = base_url() ."tags/".$slug;
$config["total_rows"] = $postdatacount;
$config["per_page"] = 6;
$config["uri_segment"] = 2;
$config['full_tag_open'] = '<ul class="pagination">';
$config['full_tag_close'] = '</ul>';
$config['first_link'] = false;
$config['last_link'] = false;
$config['first_tag_open'] = '<li>';
$config['first_tag_close'] = '</li>';
$config['prev_link'] = '&laquo';
$config['prev_tag_open'] = '<li class="prev">';
$config['prev_tag_close'] = '</li>';
$config['next_link'] = '&raquo';
$config['next_tag_open'] = '<li>';
$config['next_tag_close'] = '</li>';
$config['last_tag_open'] = '<li>';
$config['last_tag_close'] = '</li>';
$config['cur_tag_open'] = '<li class="active"><a href="#">';
$config['cur_tag_close'] = '</a></li>';
$config['num_tag_open'] = '<li>';
$config['num_tag_close'] = '</li>';
$this->pagination->initialize($config);
$page = ($this->uri->segment(2)) ? $this->uri->segment(2) : 0;
$data["links"] = $this->pagination->create_links();
$data["title"] = "All Tags";
$data["description"] = "All Tags";
$data['snippets_tags'] = $this->Constant_model->get_tags($config["per_page"],$page,$slug);
$this->snippetfunctions->add_count('tags','tag_name',$slug);
$this->load->view('view_tag_snippets', $data);
}else {
$data["title"] = "No Snippet Found for this Tag";
$data["description"] = "No Snippet Found for this Tag";
$data["slug"] =$slug;
$this->load->view('error_tags',$data);
}
}else{
$this->load->view('404',$data);
}
}
Primary URL Made on this function is
http://127.0.0.1/Mytredin_codesup/tags/user-interface
When I am clicking on Next button following URL is made but not loading the next data but loading the same data and the same thing happens on every next page.
http://127.0.0.1/Mytredin_codesup/tags/user-interface/1
Routes I am using is
$route['tags/(:any)/(:num)'] = 'tags/view/$1/$2';
$route['tags/(:any)'] = 'tags/view/$1';

The problem is with the config $config["uri_segment"] = 2;, according to your routing the page variable is at segment 3.
Use $config["uri_segment"] = 3; instead of $config["uri_segment"] = 2;. Also change the line $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
