required_without_all 驗證器一遍又一遍地重復錯誤消息

Question

我正在建立一個花名冊系統作為一個副項目，在其中一個頁面上，您可以更改某人的正常工作時間。

在頁面上，我有一個一周中每一天的復選框，然后您可以通過 go 和 select 該人工作的適當日期。

他們至少需要工作一天，因此提交時至少需要勾選其中一個復選框。

為了測試這一點，我使用了 Laravel 驗證器的required_without_all規則。

它工作得很好，但是如果沒有選中任何框，它會將您重定向回來並吐出相同的錯誤消息 7 次（因為一周中的每一天都有 7 個復選框）。

我正在使用自定義錯誤消息，所以這就是錯誤消息相同的原因，但即使我不這樣做，我也不希望一遍又一遍地重復類似的錯誤消息。

這是我的驗證器的樣子：

$validator = Validator::make($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();
        }

因此，如果提交時未選中任何框，則錯誤Surely they are working at least one day! 顯示 7 次。

我在頁面上顯示這樣的錯誤：

@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

無論如何只能讓它顯示一次？

有很多方法可以解決這個問題。 由於 JS hack 也在討論中，我們也可以從 Blade 端進來並執行此操作（隨意使用您自己喜歡的數組操作函數）：

<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>

另一種方法是使用After Validation Hook 處理驗證器中的Illuminate\\Contracts\\Support\\MessageBag並清理那里的內容。

為時已晚，但可能會幫助遇到類似問題的人。 只需將規則應用於假設字段，例如，如下所示的weekdays 。

$validator = Validator::make($request->all(), [
            'weekdays' => 'required_without_all:mondayCheckbox,tuesdayCheckbox,wednesdayCheckbox,thursdayCheckbox,fridayCheckbox,saturdayCheckbox,sundayCheckbox',
            'effective_from' => 'date',
            ], [
            '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!',
            ]);

並把所有字段(mondayCheckbox.... sundayCheckbox)你想后應用此規則required_without_all 。 並且只為規則編寫一次驗證消息。

您可以使用array_unique($array) function 從錯誤消息中刪除重復項。

這是代碼片段

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