Pagination can not back to prev number - php

Question

I have pagination, and my pagination is working fine if I click next number.
View :
1 2 >
if I am clicking on 2 it goes on second page and shows proper result.but if I want to come back on 1 than its not redirect to page 1. here is my controller code:
public function index($date_start = 'all', $date_end = 'all', $title = 'all', $cid = 0, $skpd = 'all', $offset = NULL)
{
if($_POST)
{
$filter = array(
($this->input->post('filter_date_start') == '') ? 'all' : $this->input->post('filter_date_start'),
($this->input->post('filter_date_end') == '') ? 'all' : $this->input->post('filter_date_end'),
($this->input->post('filter_title') == '') ? 'all' : $this->input->post('filter_title'),
($this->input->post('filter_kategori') == 0) ? 0 : $this->input->post('filter_kategori'),
($this->input->post('filter_skpd') == '') ? 'all' : $this->input->post('filter_skpd')
);
$url = implode('/', $filter);
redirect('document/index'.$url);
}
//echo urldecode($title);

Please master how to fix it ? whst is problem on my pagination

Answer 1

Please try this :
$config['base_url'] = site_url('document/index/'.
$date_start.'/'.$date_end.'/'.
$title.'/'.(empty($cid) ? 0 : $cid).'/'.$skpd.'/'
);
$config['uri_segment'] = 8;
in your base_url you missed out / at the end and codeigniter places offset for pagination. Hence, uri_segment would be 8.
