Laravel 表单数组验证不起作用

Question

我在使用 Laravel 5.1 验证数组时遇到问题。

HTML 代码：

{!! Form::label('information[1][color]', 'Color') !!}
{!! Form::select('information[1][color]', [null => 'Choose your color'] + $product->availableColors()->toArray() , null, ['id' => 'select-color0', 'data-id' => $product->id, 'class' => 'form-control', 'required' => 'required']) !!}

测试数据是否正确传递：

dd($request->all):

"information" => array:1 [▼
    1 => array:1 [▼
      "color" => "2"
    ]
  ]

验证码：

public function store(Request $request)
    {
        $rules = [
            'information.*.color' => 'required'
        ];

        $validator = Validator::make(Input::all(), $rules);

        if($validator->fails()){
            dd('Validation fails');
            return Redirect::to('index')->withErrors($validator);
        } else {
            ..........

我一直在dd('Validation fails') 的页面结束。有人可以向我解释我在这里缺少什么以及为什么验证不起作用吗？我正在尝试遵循本教程：https://mattstauffer.com/blog/form-array-validation-in-laravel-5-2/

我也试过了：

$validator = Validator::make($request->all(), [
    'information' => 'required',
    'information.*.color' => 'required'
]);

但验证仍然失败

还尝试更改表单名称：

{!! Form::select('information[][color]', [null => 'Choose your color'] + $product->availableColors()->toArray() , null, ['id' => 'select-color0', 'data-id' => $product->id, 'class' => 'form-control', 'required' => 'required']) !!}

但还是没有运气

Answer 1

解决方案：

$rules = [
        'id' => 'required',
        'name' => 'required|string',
        'information' => 'required|array'
    ];

    foreach ($request->information as $key => $variant) {
        foreach($variant as $color){
            $rules['information.'.$key.'.color'] = 'required';
        }
    }

    $validator = Validator::make($request->all(), $rules);

Answer 2

从选择名称中删除 1

{!! Form::select('information[][color]', array_merge([null => 'Choose your color'],$product->availableColors()->toArray()) , null, ['id' => 'select-color0', 'data-id' => $product->id, 'class' => 'form-control', 'required' => 'required']) !!}

或将您的规则更改为

$rules = [
            'information.1.color' => 'required'
        ];
