How to validate array in Laravel with Request?

Question

I send to Laravel this JSON data:

[
  {"name":"...", "description": "..."},
  {"name":"...", "description": "..."}
]

I have a StoreRequest class extends FormRequest:

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class StoreRequest extends FormRequest
{
    public function authorize()
    {
        return true;
    }

    public function rules()
    {
        return [
            'name' => 'required|string|min:1|max:255',
            'description' => 'nullable|string|max:65535'
        ];
    }
}

In my controller I have this code, but it doesn't work with array:

    public function import(StoreRequest $request) {
        $item = MyModel::create($request);

        return Response::HTTP_OK;
    }

I found this solution to handle arrays in the Request rules():

    public function rules()
    {
        return [
            'name' => 'required|string|min:1|max:255',
            'name.*' => 'required|string|min:1|max:255',
            'description' => 'nullable|string|max:65535'
            'description.*' => 'nullable|string|max:65535'
        ];
    }

How can I update the StoreRequest and/or the import() code to avoide duplicate lines in rules()?

Yeah, I'm sorry. I overlooked the [] and was confused. Please have a look at the linked question and my answer there. — Namoshek

@Namoshek: I think this isn't a duplicate... In this linked site they use $validator = Validator::make() what I don't use, because I have a StoreRequest class. Or if this is a same thing, then I dont understand how can I use this two together. — netdjw

The rules returned by the rules() method are used to create a Validator as discussed in the other question. It is the same thing, just an abstraction of it... — Namoshek

Basically, form request classes (like your StoreRequest) are used to extract logic from the controller. You can do exactly the same stuff also with a normal Request object and the Validator in your controller. It is still recommended to use form requests in order to keep your controller small and simple. — Namoshek

As you have an array of data you need to put * first:

public function rules()
{
   return [
       '*.name' => 'required|string|min:1|max:255',
       '*.description' => 'nullable|string|max:65535',
   ];
}

Will this working with a single (non array) objects too?

No, this would require the rules without *.. You can't do both in one ruleset without duplication. IMHO the best way would be to always send an array or use two different FormRequests as they are doing two different things (creating one record vs. creating many records).
