required_without_all验证器一遍又一遍地重复出现错误消息

Question

我正在构建一个名册系统作为一个侧面项目，并且在其中一个页面上，您可以更改某人工作的常规时间。

在页面上，我有一个星期的每一天的复选框，然后您可以通过并选择该人工作的适当天数。

他们需要工作至少一天，所以至少有一个复选框需要在提交时进行检查。

为了测试这个，我使用了Laravel验证器的required_without_all规则。

它可以很好地工作，但是如果没有选中框，它会将您重定向回7次并吐出相同的错误消息（因为每周有7个复选框）。

我正在使用自定义错误消息，所以这就是为什么错误消息是相同的，但即使我没有，我不会希望类似的错误消息反复重复。

这是我的验证的样子：

$validator = Validator::make($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，如果没有框是在提交检查，错误Surely they are working at least one day!如图7倍。

我喜欢这个页面上显示的错误：

@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 

反正有没有只得到它显示一次？

有很多方法可以解决这个问题。由于JS黑客是在桌子上也一样，我们也可以从叶片端进来，这样做（随意使用自己喜欢的数组操作功能）：

<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> 

另一种方式是对付在你的验证器中的Illuminate\Contracts\Support\MessageBag与After Validation Hook并清理那里。
