How to make pagination
Here my code in controller :
public function index()
{
$keyword = $this->input->get('s');
$config['per_page'] = 2;
$config['uri_segment'] = 2;
$config['full_tag_open'] = '<nav class="pagination"><ul>';
$config['full_tag_close'] = '</ul></nav>';
$config['num_tag_open'] = '<li>';
$config['num_tag_close'] = '</li>';
$config['cur_tag_open'] = '<li class="active"><a href="'.site_url(uri_string()).'">';
$config['cur_tag_close'] = '<span class="sr-only">(current)</span></a></li>';
$config['prev_tag_open'] = '<li>';
$config['prev_tag_close'] = '</li>';
$config['next_tag_open'] = '<li>';
$config['next_tag_close'] = '</li>';
$config['first_link'] = '«';
$config['prev_link'] = '‹';
$config['last_link'] = '»';
$config['next_link'] = '›';
$config['first_tag_open'] = '<li>';
$config['first_tag_close'] = '</li>';
$config['last_tag_open'] = '<li>';
$config['last_tag_close'] = '</li>';
$config['base_url'] = site_url('search');
$config['total_rows'] = $this->m_home->count_search_produk($keyword);
$this->pagination->initialize($config);
$data['results'] = $this->m_home->search_produk($keyword, $config['per_page'], 0);
$data['pagination'] = $this->pagination->create_links();
$data['total'] = $this->m_home->count_search_produk($keyword);
$this->theme->frontend('f_home/search', $data);
}
in this line :
$data['results'] = $this->m_home->search_produk($keyword, $config['per_page'], 0);
I set offset 0, I want to set dinamicly, using uri_segment, but not work, how to do that?
when I click pagination, the url like this:
myproject/search?s=a&page=3

Its working very well
public function search()
{
$keyword = $this->input->get('s');
$data['title'] = 'Search Results';
$config['per_page'] = 2;
$config['uri_segment'] = 2;
$config['full_tag_open'] = '<nav class="pagination"><ul>';
$config['full_tag_close'] = '</ul></nav>';
$config['num_tag_open'] = '<li>';
$config['num_tag_close'] = '</li>';
$config['cur_tag_open'] = '<li class="active"><a href="'.site_url(uri_string()).'">';
$config['cur_tag_close'] = '<span class="sr-only">(current)</span></a></li>';
$config['prev_tag_open'] = '<li>';
$config['prev_tag_close'] = '</li>';
$config['next_tag_open'] = '<li>';
$config['next_tag_close'] = '</li>';
$config['first_link'] = '«';
$config['prev_link'] = '‹';
$config['last_link'] = '»';
$config['next_link'] = '›';
$config['first_tag_open'] = '<li>';
$config['first_tag_close'] = '</li>';
$config['last_tag_open'] = '<li>';
$config['last_tag_close'] = '</li>';
$config['page_query_string'] = TRUE;
$config['query_string_segment']= 'page';
$config['base_url'] = site_url('search?s='.$keyword);
$config['total_rows'] = $this->m_home->count_search_produk($keyword);
$this->pagination->initialize($config);
$page = (empty($_GET['page'])) ? 0 : $_GET['page'];
$data['results'] = $this->m_home->search_produk($keyword, $config['per_page'], $page);
$data['pagination'] = $this->pagination->create_links();
$data['total'] = $this->m_home->count_search_produk($keyword);
$this->theme->frontend('f_home/search', $data);
}
