                $this->form_validation->set_rules('title','Title','required');
                if($this->form_validation->run() === FALSE) {

                }
                else {
                    $this->load->model('Posts_Model');
                    $data = array(
                        'title' => $this->input->post('title'),
                        'body' => $this->input->post('body'),
                        'cover' => $this->input->post('cover'));
                        //---image upload ---//
                        $config['upload_path']          = './uploads/';
                        $config['allowed_types']        = 'gif|jpg|png';

                        $this->load->library('upload', $config);
                        if ( ! $this->upload->do_upload('cover')) {
                            $error = array('error' => $this->upload->display_errors());
                            $this->load->view('posts/add', $error);
                        } else {
                            $data =  $this->upload->data();
                            $cover = $data['file_name'];
                            $data['cover'] = $cover;
                        }

                        //---End image upload---//
                    $this->Posts_Model->insert($data);

                    $query = $this->db->get("posts");
                    $data['records'] = $query->result();
                    $this->load->view('posts/index',$data);
                }

            }

double check your table 'post', and see if file_name field exist in the table,
