                    </form>

控制器

public function postRegister(Request $request) {

    $this->validate($request, [
        'email' => 'required|email|max:255',
        'password'  =>'required|alphaNum|Between:4,8|Confirmed',
        'password_confirmation'=>'required|alphaNum|Between:4,8',
        'fullname' => 'required|max:255',
        'activated' => 'required',
    ]);

    Admin::create([
        'email' => $request->input('email'),
        'password' => $request->input('password'),
        'fullname' => $request->input('fullname'),
        'activated' => $request->input('activated')
    ]);

    return redirect('backoffice/register')->with('info', 'register successfully!');

}

路线

Route::get('backoffice/register', 'AdminAuthController@getRegister');
Route::post('/backoffice/register', 'AdminAuthController@postRegister');

【解决方案1】：

您的刀片是否显示错误？我的意思是这个

@if($errors->any())
   <ul class="alert alert-danger">
      @foreach ($errors->all() as $error)
           <li >{{ $error }}</li>
       @endforeach
    </ul>
@endif

如果你在控制器中验证数据，你也可以这样做

    public function postRegister(Request $request)
    {
       $validator = Validator::make($request->all(), [
        'title' => 'required|',
        'body' => 'required',
        // your validation here...
    ]);

    if ($validator->fails()) {
       return redirect('youFormPage')->withErrors($validator)->withInput();
     }
   }
