codeigniter pagination not working as expected -

i tried lot cant seem figure out this, appreciated. articles have votes, , have page supposed show voted articles. using codeigniter btw. controller:

function most_voted()     {         $per_page = 3;         $cur_page = $this->uri->segment(4);         /*         if($cur_page == "") $cur_page = 1;         else $cur_page = (integer)$cur_page;         */         $offset = ($cur_page - 1) * $per_page;         if($offset < 0) $offset = 0;         $this->load->model('article_model');         $result_rows = $this->article_model->getmostvoted($per_page,$cur_page);         $total_rows = sizeof($result_rows) + 10;         echo "total rows : ".$total_rows.'<br>';         echo "cur page   : $cur_page <br>";          //$this->load->library('pagination');         $config['base_url'] = base_url().'articles/most_voted/page/';         $config['uri_segment'] = 4;         $config['num_links'] = 3;         $config['first_link'] = '<<first';         $config['last_link'] = 'last>>';         $config['prev_link'] = '< previous';         $config['next_link'] = 'next >';         $config['total_rows'] = $total_rows;         $config['per_page'] = $per_page;         $this->pagination->initialize($config);           $data['articles'] = $result_rows;         $data['view_file_name'] = 'articles/all_articles_view';         $this->load->view('includes/template',$data);         //echo $this->db->last_query();     } 

the model :

function getmostvoted($limit,$offset)     {         $this->db->order_by('votes','desc');         $q=$this->db->get('cgh_articles',$limit,$offset);         if($q->num_rows() > 0)         {             foreach($q->result() $row)             {                 $data[] = $row;             }             return $data;         }     } 

the problem : issue though pagination < previous 1 2 3 4 5 next > clicking on 2 goes url : page/3 clicking on 3 goes url : page/6 clicking on 4 goes url : page/9 , on. want click on 2 go page/2, 3 page/3, , on. suggestions whats going wrong?

if need more info, please let me know, thanks.

the way pagination class works returns item @ page should start.

for example, url : hostanme/controller/page/9 means page should rendered starting 9th voted article. see example in codeigniter documentation.

also, have $total_rows = sizeof($result_rows) + 10;. why ?
