验证Laravel中的关联数组

Question

I have a JSON structure like this which I want to validate.

{
  "result":[{

            "product_id": 1,
            "client": 49,
            "ticket": 2,
            "sold_from_date": 1431588871,
            "sold_to_date": 1433122200,
            "discount_given":18,
            "cheques":[{
              "cheque_number" : 123456,
              "amount": 6000,
              "cheque_date": 1433122200,
              "bank": "UCD"
            },
            {"cheque_number" : 456234,
              "amount": 6000,
              "cheque_date": 1433122200,
              "bank": "AMB"
            }
            ]
        },
          {

            "product_id": 1,
            "client": 49,
            "ticket": 2,
            "sold_from_date": 1433122200,
            "sold_to_date": 1434688959
        }]
}

I want to validate this JSON in Laravel.

I tried doing this:

$validator = \Validator::make($data, []);

        $validator->each('result.product_id' , ['required|numeric']);
        $validator->each('result.sold_from_date' , ['required|numeric']);
        $validator->each('result.sold_to_date' , ['required|numeric']);
        $validator->each('result.cheques.cheque_number' , ['sometimes|required|numeric']);
        $validator->each('result.cheques.amount', ['sometimes|required|numeric']);

        return $validator;

I am getting this error every time:

Attribute for each() must be an array.

Also, how can I validate cheques? Because it can or cannot be in JSON.

Answer 1

Create an array from json with json_decode function.

Try:

$dataarray = json_decode($data);

$validator = \Validator::make($dataarray['result'][0], [
    'product_id' => 'required|numeric',
    'sold_from_date' => 'required|numeric'
]);

iterate the array:

$roles = array(
    'product_id' => 'required|numeric',
    'sold_from_date' => 'required|numeric'
);

foreach($data as $element)
{
    foreach($element as $value) {
        $validator = \Validator::make($value, $roles);
    }
}
