我正在尝试在数据库中选择的字段重复时显示错误消息。为此,我使用了 Laravel 验证规则 required unique。但是我遇到了重定向问题。以下是存储控制器的代码:
public function store() {
$rules = array(
'car' => array('required', 'unique:insur_docs,car_id'),
);
$validation = Validator::make(Input::all(), $rules);
if ($validation->fails()) {
// Validation has failed.
return Redirect::to('insur_docs/create')->with_input()->with_errors($validation);
} else {
$data = new InsurDoc();
$data->ownership_cert = Input::get('ownership_cert');
$data->authoriz = Input::get('authoriz');
$data->drive_permis = Input::get('drive_permis');
$data->sgs = Input::get('sgs');
$data->tpl = Input::get('tpl');
$data->kasko = Input::get('kasko');
$data->inter_permis = Input::get('inter_permis');
$data->car_id = Input::get('car');
$data->save();
// redirect
return Redirect::to('/');
}
}
这里是路由
Route::get('insur_docs/create', array('as' => 'insur_docs.create','uses' => 'Insur_DocController@create'));
创建控制器
public function create() {
$cars = DB::table('cars')->orderBy('Description', 'asc')->distinct()->lists('Description', 'id');
return View::make('pages.insur_docs_create', array(
'cars' => $cars
));
}
