Laravel form array validation doesn't work

Question

I'm having trouble with Laravel 5.1 to validate an array.

HTML CODE:

{!! 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']) !!}

To test if the data is being passed on correctly:

dd($request->all):

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

Validation code:

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 {
            ..........

I keep ending up at the page from the dd('Validation fails'). Can someone explain to me what I'm missing here and why the validation isn't working? I'm trying to follow this tutorial: https://mattstauffer.com/blog/form-array-validation-in-laravel-5-2/

I have also tried:

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

but the validation still fails

Also tried changing the form name:

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

But still no luck yet

could you please add output also?

instead of Input you should try $request.

SOLUTION:

$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);

I still think the 'information' => 'required|array' is conflicting with the elegant way, and that may not be needed... but anyways, good that you solved it!

Remove the 1 from the select name

{!! 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']) !!}

or change your roules to

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

This is also not the problem because as you can see from the dd($request->all()) the values are passed on correctly. Somehow the validation isn't working on the array.

now that update, which is a different point, actually is closer to what the issue is

@lagbox maybe you can help answering the question instead of just saying what is wrong!

@madalinivascu thank you for the updated suggestion. I think this is indeed closer to solving the problem. The form is dynamic. So a user can add another color input form. I'm currently working on just getting the validation for a single color to work.

@AnnaJeanine are you submitting the form via ajax or via a input form?do you have any other inputs on the form?
