Controller:

Code:
function index()

    {

        $data['title'] = "Fabriken Fredag | Bildgalleri";

        $this->load->library('pagination');

        $config['base_url'] = site_url('/galleri/index/');

        $config['total_rows'] = $this->db->count_all_results('albums');

        $config['per_page'] = 4;

        $config['uri_segment'] = 3;

        $config['first_link'] = 'F&ouml;rsta';

        $config['last_link'] = 'Sista'; 

        $this->pagination->initialize($config);

        //DB

                //Doesn't matter which one on of $data['albums'] i'm chosing.

        $data['albums'] = $this->db->get('albums');

        //$data['albums'] = $this->galleryModel->All($config['per_page'], $this->uri->segment(3));

        $this->load->view('galleri_view', $data);    

}

Viewer:

Code:
&lt;?php if(empty($albums)): echo "Empty! :S"; ?&gt;

        &lt;?php else: ?&gt;

        <h2>Bildgalleri!</h2>

            &lt;?php foreach($albums->result() as $row): ?&gt;

                &lt;?php echo $row->title; ?&gt;<br />

            &lt;?php endforeach; ?&gt;

        &lt;?php endif; ?&gt;

If I do a var_dump($albums) the result is:

Quote:object(CI_DB_mysql_result)#18 (7) { ["conn_id"]=> resource(30) of type (mysql link persistent) ["result_id"]=> resource(40) of type (mysql result) ["result_array"]=> array(0) { } ["result_object"]=> array(0) { } ["current_row"]=> int(0) ["num_rows"]=> int(0) ["row_data"]=> NULL }

Don't check empty. In the manual the examples show checking num_rows(). So try checking $albums->num_rows().

Thanks! It's weird that the exact same code, but in other controllers and views files worked as I wanted.
