如何在laravel 5.3中验证数组？

Question

My case is like this :

My view :

{!! Form::open(['url' => 'product/store', 'class'=>'form-horizontal', 'method'=>'POST', 'files' => true]) !!}
    ...
    <input type="file" class="form-control" name="photo[]" multiple>
    ...
{!! Form::close() !!}

My controller :

public function store(CreateProductRequest $request)
{
    dd($request->all());
    ...
}

I set required here :

<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class CreateProductRequest extends FormRequest
{
    public function authorize()
    {
        return true;
    }
    public function rules()
    {
        return [
            'name'=>'required',
            ...
            'photo[]'=> 'required|mimes:jpeg,bmp,png,jpg|max:7024',
        ];
    }
}

When the name is array, it does not work

When I click submit, it will back to form add

How can I solve this problem?

Answer 1

Do this. It will work.

'photo.*' => 'required|mimes:jpeg,bmp,png,jpg|max:7024'

Answer 2

如果要验证数组形式字段，则可以使用*字符检索每个数组元素的所有消息：

'photo.*' => 'required|mimes:jpeg,bmp,png,jpg|max:7024'

Answer 3

'photo'=>'required | array'，'photo。*'=>'mimes：jpeg，bmp，png，jpg | max：7024'

Answer 4

For assoc array like:

$skills = [['id'=> 1, 'name' => 'photoshoot', photo => File], ['id'=>2, 'name'=> 'someskill', photo => File]];

For validate in DB validation rule will be like this:

'skills.*.id' => 'required|exists:skills,id',
'skills.*.photo' => 'required|mimes:jpeg,bmp,png,jpg|max:7024'
