Validation 验证后填充的字段将变为空

Validation 验证后填充的字段将变为空,validation,laravel,Validation,Laravel,我创建了一个带有验证的laravel表单，这里的问题是，当我保留空字段时，它会显示错误消息（这没问题），但是如果我填充了一些字段，而其他字段没有，它会刷新，然后现在填充的字段是空的，并且还会显示该字段的错误消息 public function store() { $data = [ "errors" => null ]; $rules = array( "car" => "required

public function store() {
        $data = [
            "errors" => null
        ];
        $rules = array(
            "car" => "required|unique:insur_docs,car_id", 
            "ownership_cert" => "required",
            "authoriz" => "required",            
            "drive_permis" => "required",
            "sgs" => "required",
            "tpl" => "required",
            "kasko" => "required",
            "inter_permis" => "required",
        );
        $validation = Validator::make(Input::all(), $rules);
        $cars = DB::table('cars')->orderBy('Description', 'asc')->distinct()->lists('Description', 'id');  
        if ($validation->passes()) {
            $doc = new InsurDoc();
            $doc->ownership_cert = Input::get('ownership_cert');
            $doc->authoriz = Input::get('authoriz');
            $doc->drive_permis = Input::get('drive_permis');
            $doc->sgs = Input::get('sgs');
            $doc->tpl = Input::get('tpl');
            $doc->kasko = Input::get('kasko');
            $doc->inter_permis = Input::get('inter_permis');
            $doc->car_id = Input::get('car');
            $doc->save();
            return Redirect::to('/');
        } else {
            $data['errors'] = $validation->errors();
            $data['cars'] = $cars;
                return View::make('pages.insur_docs_create', $data);
        }
    }

@if（$errors->count（）>0）
发生了以下错误：


@foreach（$errors->all（）作为$message）
{{Helpers\Helper:：macro（$message）}
@endforeach
