Validate 2nd Level Array/JSON using Laravel Validator

Let say I have this JSON request to my Laravel Route

{
    "user_id":1,
    "payment_type":"point",
    "order_boxes":[
        {
            "for_friend_name":"Yansen",
            "order_box_items":[
                {
                    "product_id": 1,
                }    
            ]
        }    
    ]
}

I can validate the request up to "order_boxes" array level using Laravel Validator using this code :

$rules = [
            'user_id' => 'required|exists:users,id',
            'payment_type' => 'required|in:point,cod,transfer,credit_card',
            'order_boxes' => 'required|array',
        ];

        $validator = Validator::make($request->all(), $rules);
        $validator->each('order_boxes',[
            'for_friend_name' => ['max:25'],
            'order_box_items' => ['required','array']
        ]);

As you can see for the "order_box_items" which inside the "order_boxes", I add another "array" rules and try to validate the array again. And I add this code below :

$validator->each('order_box_items',[
    'product_id' => ['required','exists:products,id']
]);

But it returns "Attribute for each() must be an array".

So I believe the $validator->each() can only validate the first level of the array only. Any idea on how to validate the second level of the array using it?

Thank you

This feature will be added in Laravel 5.2. Until then use solutions like @YansenTan posted.

I managed to validate the nested array by using "foreach":

$rules = [
    'user_id' => 'required|exists:users,id',
    'payment_type' => 'required|in:point,cod,transfer,credit_card',
    'order_boxes' => 'required|array',
];

foreach($request->input('order_boxes') as $key => $value){
    $rules['order_boxes.'.$key.'.for_friend_name'] = 'max:25';
    $rules['order_boxes.'.$key.'.order_box_items'] = 'required|array';

    foreach($request->input('order_boxes')[$key]['order_box_items'] as $item_key => $item_value){
        $rules['order_boxes.'.$key.'.order_box_items.'.$item_key.'.product_id'] = 'required|exists:products,id';
    }
}
