unlink photo

[eluser]Thiago Leao[/eluser]
I can delete the path from the bank, but I can not delete the files.

Well I know I have to return an object to delete, but I can not, can someone help me?
thanks

Code:

function removePhoto($id_pictures){
        
        $sql = $this->db->where('id_pictures', $id_pictures);
        $this->db->delete('pictures');
        
        $query = $this->db->query($sql);
        return $query->result();
        
        unlink(base_url().$query->thumb);
        unlink(base_url().$query->imagem);
        
    }
