网址最后一段的Codeigniter分页ID

Question

Hi I have working pagination function in other sites but here

public function category($id=null)
{
    $config = array();
    $config["base_url"] = base_url() . "view/category/".$id;
    $config["total_rows"] = $this->viewmodel->record_count_category_post($data['category']);
    $config["per_page"] = 6;
    $config['num_links'] = 10;
    $this->pagination->initialize($config);  
    $page = ($this->uri->segment(4)) ? $this->uri->segment(4) : 0;
    $config['display_pages'] = FALSE;
    $data["links"] = $this->pagination->create_links();

}

I could not figure why pagination not working. How could I make pagination working if the URL contains number (id) at the last segment ?

Change your $page = ($this->uri->segment(4)) ? $this->uri->segment(4) : 0; $page = ($this->uri->segment(4)) ? $this->uri->segment(4) : 0; to:

if($this->uri->segment(4))
            {
                $config["per_page"] = (($this->uri->segment(4)) * 6) - 6;
            }
            else
            {
                $config["per_page"] = 0;
            }

Like this Sample Below:

public function category($id=null)
            {
            $config = array();
            $config["base_url"] = base_url() . "view/category/".$id;
            $config["total_rows"] = $this->viewmodel->record_count_category_post($data['category']);
            $config["per_page"] = 6;
            $config['num_links'] = 10;
            $this->pagination->initialize($config);  
        if($this->uri->segment(4))
                {
                    $config["per_page"] = (($this->uri->segment(4)) * 6) - 6;
                }
                else
                {
                    $config["per_page"] = 0;
                }
        $config['display_pages'] = FALSE;
         $data["links"] = $this->pagination->create_links();

         }

Answer 2

change public function category($id=null) to

public function category($id=0)

Because NULL will not return any segment...
