Question

现在我正在学习laravel。

我有一个问题： Blade，不想显示验证器错误。

我创建请求“ContactRequest”：

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class ContactRequest 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 [
        'name'=>'required',
    ];
}

public function messages()
{
   return [
        'name.required' => 'Er, you forgot your name!',
   ];
}
 }

只需为页面设置控制器即可。

 namespace App\Http\Controllers\Admin;

 use Illuminate\Http\Request;
 use App\Http\Requests\ContactRequest;
 use App\Http\Controllers\Controller;

 use Validator;


class ContactController extends Controller
{

public function store(ContactRequest $request) {

    return view('default.contact',['title'=>'Contacts']);
}


public function show()
{
    return view('default.contact',['title'=>'Contacts']);
}

}

只需在$ middleware的属性中添加正确的提供商：

protected $middleware = [
         \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \Illuminate\Session\Middleware\StartSession::class,
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
];

创建了2个路由器：

Route::get('/contact',['uses'=>'Admin\ContactController@show','as'=>'contact']);
Route::post('/contact',['uses'=>'Admin\ContactController@store']);

（试图将它们组合成一组middleware => web（没有帮助））

@if (count($errors) > 0)
<div class="alert alert-danger">
    <ul>
        @foreach ($errors->all() as $error)
            <li>{{ $error }}</li>
        @endforeach
    </ul>
</div>
@endif

<div class="form-area">  
    <form method="post" action="{{ route('contact') }}">
    {{ csrf_field() }}

                <div class="form-group">
        <input type="text" class="form-control" value="{{ old('name') }}" id="name" name="name" placeholder="Name">
      </div>

      <div class="form-group">
        <input type="text" class="form-control" value="{{ old('email') }}" id="email" name="email" placeholder="Email">
      </div>

      <div class="form-group">
        <input type="text" class="form-control" value="{{ old('site') }}" id="site" name="site" placeholder="site">
      </div>

                <div class="form-group">
                <textarea class="form-control" type="textarea" name="text" id="message" placeholder="Message" maxlength="140" rows="7">{{ old('text') }}</textarea>
                    <span class="help-block"><p id="characterLeft" class="help-block ">You have reached the limit</p></span>                    
                </div>

             <input type="submit" id="submit" name="submit" class="btn btn-primary">
    </form>
</div>

但最后，提交表单时，不会显示错误消息。请告诉我该怎么办？谢谢。

如果验证失败，您可以重定向错误：

$validator=Validator::make($request->all(),[
    'name'=>'required']); 
if($validator->fails())
{
    return redirect("/contact")->withErrors($validator);    
}

然后，在视图中：

@if (count($errors) > 0)
<div class="alert alert-danger">
    <ul>
        @foreach ($errors->all() as $error)
            <li>{{ $error }}</li>
        @endforeach
    </ul>
</div>
@endif

Laravel 5.3 $错误没有出现在Blade中
