Question

我在托管上使用Laravel 5.4。我的验证方法正常，但它不显示消息。我做了显示错误所需的所有操作，但它不起作用。

@if($errors->has('recipient'))
<div class="form-group">
<label class="col-lg-2 control-label"></label>  
<div class="col-lg-10">                     
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->get('recipient') as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
</div>
</div>
@endif

我使用{{ csrf_field() }}令牌。如果使用了错误的用户类型，则验证规则有效，但不显示消息。

我的send方法：

public function send(Request $request)
{
   $this->validator($request->all())->validate();
   $this->create($request->all());
   return redirect($this->redirectToAfterSendMessage);
}

我的验证码：

protected function validator(array $data)
{        
    return Validator::make($data, [

        "$this->recipient" => [
            'sometimes',
            'required',
            'email',
            'exists:users,email',
            Rule::notIn([auth()->user()->email])
        ],

        "$this->subject" => 'sometimes|required|min:10',

        "$this->message" => 'sometimes|required|min:50',

    ], $this->validator_messages());
}

我的路线：

Route::get('/compose', 'InboxController@compose')     ->name('compose');
Route::post('/compose', 'InboxController@send');

dump($errors)的结果：

ViewErrorBag {#244 ▼
  #bags: []
}

Answer 1

您需要更改：

"$this->recipient"
"$this->subject" 
"$this->message"

要：

'recipient'
'subject'
'message'

Answer 2

<强> EDITED

要解决当前问题，请将$errors->get('recipient')更改为$errors->all()。

它应该是这样的：

@foreach ($errors->all() as $error)
   <li>{{ $error }}</li>
@endforeach

这不是您问题的直接解决方案。然而，比你更好的方法（imo）是自定义请求。您可以使用以下命令快速生成自定义请求：

php artisan make:request CustomRequest

之后，您可以将类型从Request更改为CustomRequest

public function send(CustomRequest $request)
{
   $this->create($request->all());
   return redirect($this->redirectToAfterSendMessage);
}

在CustomRequest.php中，您可以像这样提取验证逻辑：

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class CustomRequest 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',
            'email' => 'required',
            'message' => 'required',

        ];
    }

    public function messages()
    {
        return [
            'name.required' => 'Name is required.',
            'email.required' => 'Email is required.',
            'message.required' => 'Message is required.',
        ];
    }
}

希望这有帮助。
