How To Validate Array Values

[thomassmith10]

Is it possible to validate array values?

For example I want to validate that every value in an array is a uuid...

<?php

namespace App\Dtos;

use Spatie\LaravelData\Attributes\Validation\Uuid;
use Spatie\LaravelData\Data;

class MyDTO extends Data
{
    public function __construct(
        public string $title,

        // TODO validate each value of the array by `#[Uuid]`
        public array $array_of_uuids,
    ) {
    }
}

Using Laravel Rules I would do it this like...

'array_of_uuids' => 'required|array',
'array_of_uuids.*' => 'required|uuid',

Take a look at the rules method in the docs.

Where is it ?

Say I want to validate an array of enums or an array of int ? I don't see a rule for that and the rule ArrayType doesn't support something similar to ensure from Laravel collection ?

I searched but can't find.

You can define a static rules method and then add the rules over there like you would in a regular Laravel request

Thank you.

That we knew. I should of mentioned I was looking for a way with an attribute already built in in the package.

ArrayType could be modified to do the above or a new attribute ArrayOfType

We'll keep the attributes as close to Laravel as possible, but you can always create your own validation attribute.

If you want to avoid to create your own rule, you can just do it like that:

class MyData extends Data
{
    public function __construct(
        public array $uuids,
    ) {
    }

    public static function rules(): array
    {
        return [
            'uuids.*' => [new Required, new StringType, new Max(32)],
        ];
    }
}
