About pagination

I am using CI3 and the pagination is not working on the second page. Is that i am missing something? Here is my code from the controller:

PHP Code:

public function tags($task = "list")
    {
        $header['title'] = 'Tag List';
        $this->load->view("template/header", $header);
        $this->load->view("template/dashboardNavView");

        $builder ['task'] = $task;

        if($task == "list" || $task == "")
        {

            $pager['base_url'] = "/dashboard/tags/";
            $pager['total_rows'] = $this->db->count_all('tags');
            $pager['per_page'] = 4;
            $pager["uri_segment"] = 3;
            $this->pagination->initialize($pager);

            $page = $this->uri->segment(3);

            $builder['tags'] = $this->db->order_by('id', 'DESC')->limit($pager['per_page'], $page)->get('tags')->result();
            $builder['pager'] = $this->pagination->create_links();

        }

        $this->load->view("tags/TagsBuilderView", $builder);
        $this->load->view("template/footer");
    } 


Everything seems ok, but when i click on the second link then empty view returned.

Try to this without the / ...

$pager['base_url'] = "/dashboard/tags";

Thankyou for your response, i tried with
$pager['base_url'] = "/dashboard/tags";
but it doesn't work also i tried with full url with no success.

What about $pager['base_url'] = "/dashboard/tags/list";

Many thanks @Rufnex for your time, you point me into the right direction. However shipping everything into a new method seems works just perfect!

Glad to help you
