required_without_all驗證器一遍又一遍地重複出現錯誤消息

Question

我正在構建一個名冊系統作爲一個側面項目，並且在其中一個頁面上，您可以更改某人工作的常規時間。

在頁面上，我有一個星期的每一天的複選框，然後您可以通過並選擇該人工作的適當天數。

他們需要工作至少一天，所以至少有一個複選框需要在提交時進行檢查。

爲了測試這個，我使用了Laravel驗證器的required_without_all規則。

它可以很好地工作，但是如果沒有選中框，它會將您重定向回7次並吐出相同的錯誤消息（因爲每週有7個複選框）。

我正在使用自定義錯誤消息，所以這就是爲什麼錯誤消息是相同的，但即使我沒有，我不會希望類似的錯誤消息反覆重複。

這是我的驗證的樣子：

$validator = Validator::make($request->all(), [ 
      'mondayCheckbox' => 'required_without_all:tuesdayCheckbox,wednesdayCheckbox,thursdayCheckbox,fridayCheckbox,saturdayCheckbox,sundayCheckbox', 
      'tuesdayCheckbox' => 'required_without_all:mondayCheckbox,wednesdayCheckbox,thursdayCheckbox,fridayCheckbox,saturdayCheckbox,sundayCheckbox', 
      'wednesdayCheckbox' => 'required_without_all:mondayCheckbox,tuesdayCheckbox,thursdayCheckbox,fridayCheckbox,saturdayCheckbox,sundayCheckbox', 
      'thursdayCheckbox' => 'required_without_all:mondayCheckbox,tuesdayCheckbox,wednesdayCheckbox,fridayCheckbox,saturdayCheckbox,sundayCheckbox', 
      'fridayCheckbox' => 'required_without_all:mondayCheckbox,tuesdayCheckbox,wednesdayCheckbox,thursdayCheckbox,saturdayCheckbox,sundayCheckbox', 
      'saturdayCheckbox' => 'required_without_all:mondayCheckbox,tuesdayCheckbox,wednesdayCheckbox,thursdayCheckbox,fridayCheckbox,sundayCheckbox', 
      'sundayCheckbox' => 'required_without_all:mondayCheckbox,tuesdayCheckbox,wednesdayCheckbox,thursdayCheckbox,fridayCheckbox,saturdayCheckbox', 
      'effective_from' => 'date', 
      ], [ 
      'mondayCheckbox.required_without_all' => 'Surely they are working at least one day!', 
      'tuesdayCheckbox.required_without_all' => 'Surely they are working at least one day!', 
      'wednesdayCheckbox.required_without_all' => 'Surely they are working at least one day!', 
      'thursdayCheckbox.required_without_all' => 'Surely they are working at least one day!', 
      'fridayCheckbox.required_without_all' => 'Surely they are working at least one day!', 
      'saturdayCheckbox.required_without_all' => 'Surely they are working at least one day!', 
      'sundayCheckbox.required_without_all' => 'Surely they are working at least one day!', 
      'effective_from.date' => 'You have provided an invalid date for when their hours are effective from!', 
      ]); 

     if ($validator->fails()) 
     { 
      return Redirect::back() 
       ->withErrors($validator) 
       ->withInput(); 
     } 

所以，如果沒有框是在提交檢查，錯誤Surely they are working at least one day!如圖7倍。

我喜歡這個頁面上顯示的錯誤：

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

反正有沒有隻得到它顯示一次？

有很多方法可以解決這個問題。由於JS黑客是在桌子上也一樣，我們也可以從葉片端進來，這樣做（隨意使用自己喜歡的數組操作功能）：

<ul> 

    <li> 
     {{-- Show error message only once --}} 
     @if($errors->has('mondayCheckbox') || $errors->has('tuesdayCheckbox') || $errors->has('wednesdayCheckbox') || $errors->has('thursdayCheckbox') || $errors->has('fridayCheckbox') || $errors->has('saturdayCheckbox') || $errors->has('sundayCheckbox')) 
      Surely they are working at least one day! 
     @endif 
    </li> 

    @foreach ($errors->all() as $error) 

     {{-- Show other errors not related to the checkboxes --}} 
     @unless($error == 'Surely they are working at least one day!') 
      <li> 
       {{ $error }} 
      </li> 
     @endunless 

    @endforeach 
</ul> 

另一種方式是對付在你的驗證器中的Illuminate\Contracts\Support\MessageBag與After Validation Hook並清理那裏。
