Question

我正在尝试使用laravel在单页网站上设置联系表单，我似乎无法获取表单来验证用户输入并显示表单可能存在的任何错误。< / p>

email.blade.php:

<ul>
    @foreach($errors->all() as $error)
        <li>{{ $error }}</li>
    @endforeach
</ul>
{!! Form::open(['route' => 'mail', 'method' => 'post', 'role' => 'form', 'id' => 'footer-form']) !!}
<div class="form-group has-feedback">
    {!! Form::label('first_name', null, ['class' => 'sr-only']) !!}
    {!! Form::text('first_name', null, ['class' => 'form-control', 'placeholder' => 'First Name']) !!}
    <i class="fa fa-user form-control-feedback"></i>
    @if($errors->has('first_name'))
        {{ $errors->first('first_name') }}
    @endif
</div>
<div class="form-group has-feedback">
    {!! Form::label('last_name', null, ['class' => 'sr-only']) !!}
    {!! Form::text('last_name', null, ['class' => 'form-control', 'placeholder' => 'Last Name']) !!}
    <i class="fa fa-user form-control-feedback"></i>
    @if($errors->has('last_name'))
        {{ $errors->first('last_name') }}
    @endif
</div>
<div class="form-group has-feedback">
    {!! Form::label('email', null, ['class' => 'sr-only']) !!}
    {!! Form::email('email', null, ['class' => 'form-control', 'placeholder' => 'Email address']) !!}
    <i class="fa fa-envelope form-control-feedback"></i>
    @if($errors->has('email'))
        {{ $errors->first('email') }}
    @endif
</div>
<div class="form-group has-feedback">
    {!! Form::label('textarea', null, ['class' => 'sr-only']) !!}
    {!! Form::textarea('textarea', null, ['class' => 'form-control', 'rows' => 8, 'placeholder' => 'Message']) !!}
    <i class="fa fa-pencil form-control-feedback"></i>
    @if($errors->has('textarea'))
        {{ $errors->first('textarea') }}
    @endif
</div>

{!! Form::submit('Send', ['class' => 'btn btn-default']) !!}

{!! Form::close() !!}

Route: web.php:

Route::get('/ensignhospital', [
    'as' => 'home',
    'uses' => 'HomeController@home'
]);


Route::group(['before' => 'guest'], function () {
    /*
     * CSRF Protection
     *
     * */
    Route::group(['before' => 'csrf'], function () {

        Route::post('/ensignhospital', [
            'as' => 'mail',
            'uses' => 'HomeController@postSendMail'
        ]);
    });


});

controller to handle for request:

class HomeController extends Controller {

    public function home(){
        return View('welcome');
    }



    public function postSendMail(ContactFormRequest $request){

        if($request->fails()){

            return Redirect::route('')
                ->withErrors()
                ->withInput();

        }else{

            return View('passed');
        }


    }

}

The form request validator class:

class ContactFormRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            //
            'first_name'    => 'required',
            'last_name'     => 'required',
            'email'         => 'required|email',
            'message'       => 'required'
        ];
    }
}

当我没有输入有效输入时，表单无法验证。我需要表单来验证用户输入和remain at the form position on the web page。

please note:

我使用.htaccess文件获取my computer上的网站，将site root显示为localhost/mylaravelproject，而不是通常的localhost/mylaravelprojec/public通常会在全新安装的laravel上看到。

从此处的文档：https://laravel.com/docs/5.3/validation#form-request-validation

So, how are the validation rules evaluated? All you need to do is type-hint
the request on your controller method. The incoming form request is validated 
before the controller method is called, meaning you do not need to clutter 
your controller with any validation logic.

Laravel永远不会留在表格上。它将改为重定向，验证然后重定向，并返回错误。您无需检查代码if($request->fails())。

Laravel html表单未验证表单输入
