Enums

[LocalHeroPro]

Subject of the issue

Add ability to use Enums validation rule: https://laravel.com/docs/9.x/validation#rule-enum

Your environment

• version of this package: 4.7.0
• version of Laravel: 9.4.1

Steps to reproduce

public funciton rules(): array
{
   return [
      'awesome_enum_type' => ['required', 'integer', new Enum(AwesomeEnumType::class)],
   ];
}

Expected behaviour

Validation work like as Rule::in() or something.

Actual behaviour

I see on browser: Whoops, looks like something went wrong.

Hi @LocalHeroPro

Not sure if this would be an option or even possible but it looks like you can create a JsValidator from a Laravel Validator instance https://github.com/proengsoft/laravel-jsvalidation/wiki/Basic-Usage#create-javascript-validations-using-validator-instance

I'm still trying to get it working and not even sure if the new validation rules would be included from the base validator or not...

For the time being the Laravel enum handling is very wonky in the implementation it seems, and not yet very mature.

For Example,

json_encode(['awesome_enum_type' => ['required', 'integer', new Enum(AwesomeEnumType::class)]])

returns

{"awesome_enum_type": ["required", "integer", {}]}

So new Enum(AwesomeEnumType::class) is only represented as a useless {}.

My current workaround is the following trait:

app/Enums/Traits/EnumToValidation.php

<?php

namespace App\Enums\Traits;

use Illuminate\Validation\Rule;
use Illuminate\Validation\Rules\In;

trait EnumToValidation
{
    /**
     * Return an validation object
     *
     * @return array
     */
    public static function toValidation(): In
    {
        return Rule::in(array_column(self::cases(), 'value'));
    }
}

which I embed in my enum with the use … statement:

enum AwesomeEnumType: string {
  use App\Enums\Traits\EnumToValidation;
  
  case Fruit => 'mango';
  case Website => 'https://4458.rocks';
}

And finally using it in the verification like this:

public funciton rules(): array
{
   return [
        'awesome_enum_type' => [
            'required', 
            'integer',
-           new Enum(AwesomeEnumType::class),
+           AwesomeEnumType::toValidation(),
        ], 
   ];
}

-           new Enum(AwesomeEnumType::class),
+           AwesomeEnumType::toValidation(),
        ], 
   ];
}

Thanks for this & worked with me, but & have another issue with how to make another input as required based on a value in this array.
