php - 在 Laravel 中显示输入数组的验证错误

Question

我正在向我的 Controller 提交一组输入，如下所示:

<input id="box-1-nickname" name="box-nickname[]" class="form-control" type="text" placeholder="Required">
<input id="box-2-nickname" name="box-nickname[]" class="form-control" type="text" placeholder="Required">

我正在做一些这样的验证:

$validator = Validator::make(Input::all(), array(
        'supplies-count' => 'required|in:0,1,2,3,4',
    ));

$arrayValidator = Validator::make(Input::all(), []);

$arrayValidator->each('box-nickname', ['required|min:1|max:60']);

if( $validator->fails() || $arrayValidator->fails() ) {
    return Redirect::route('route-2')
           ->withErrors($arrayValidator)
           ->withInput();
}

问题是当我尝试检查这样的错误时它不起作用:

if( $errors->has('box-1-nickname') ) { echo ' has-error'; }

在 View 中显示输入数组错误(L5.8 及以上)

获取输入数组的第一个验证错误:

{{ $errors->first('input_array.*') }}

检查输入数组中是否存在错误:

@if($errors->has('input_array.*'))
    <h1>There is an error in your input array</h1>
    <ul>
       @foreach($errors->get('input_array.*') as $errors)
           @foreach($errors as $error)
               <li>{{ $error }}</li>
           @endforeach
       @endforeach
    </ul>
@endif

其他示例:

@error('input_array.*')
    <div class="alert alert-danger">{{ $message }}</div>
@enderror

Working with error messages

If you are validating an array form field, you may retrieve all of the messages for each of the array elements using the * character:

foreach ($errors->get('attachments.*') as $message) {
    //
}

希望对你有帮助!
