                    <div class='form-group col-sm-12'>
                        <button type='submit' class='btn btn-primary'><i class='fa fa-save'></i> Simpan</button>
                    </div>
            </div><!-- /.box -->
            </form>

and this my controller :

    public function postAddSave() {
        $simpan= array();
        $simpan['id_log_patrols']=Request::input('id_log_patrols');
        if (Request::hasfile('photo1')) {
        $destinationPath = 'uploads'; // upload path
        $extension = Request::file('photo1')->getClientOriginalExtension(); // getting image extension
        $fileName = rand(11111,99999).'.'.$extension; // renameing image
        Request::file('photo1')->move($destinationPath, $fileName); // uploading file to given path
        // sending back with message
    }
        $simpan['photo1']=$fileName;
        if (Request::hasfile('photo2')) {
        $destinationPath1 = 'uploads'; // upload path
        $extension1 = Request::file('photo2')->getClientOriginalExtension(); // getting image extension
        $fileName1 = rand(11111,99999).'.'.$extension1; // renameing image
        Request::file('photo2')->move($destinationPath1, $fileName1); // uploading file to given path
    }
        // sending back with message
        $simpan['photo2']=$fileName1;
        if (Request::hasfile('photo3')) {
        $destinationPath2 = 'uploads'; // upload path
        $extension2 = Request::file('photo3')->getClientOriginalExtension(); // getting image extension
        $fileName2 = rand(11111,99999).'.'.$extension1; // renameing image
        Request::file('photo3')->move($destinationPath2, $fileName2); // uploading file to given path
        // sending back with message
        $simpan['photo3']=$fileName2;
        $simpan['description']=Request::input('description');
    }
        DB::table('log_patrol_details')->insert($simpan);
        Session::flash('success', 'Data berhasil di ditambahkan');
        return Redirect::to('log_details');
    }
    public function getEdit($id)  {
        $data['row'] = log_patrol_details::find($id);
        return view('details_form',$data);
