HELP with URL

[eluser]Evollution[/eluser]
din cate am inteles eu trebuie sa fac functia GET_ARTICLE_BY .. in model

si am facut ceva de genu

Code:

function GET_ARTICLE_BY_ID($article_id)
    {
                $this->db->select('title,news');
                $this->db->from('news');                
                $this->db->where('id', $article_id);
                 $query = $this->db->get();


        return ;
    }

.. poate incurc eu ceva :\
