PHP from Packagist Build Status Total Downloads

This package provides extended support for our spatie/enum package in Laravel.

Installation

You can install the package via composer:

composer require spatie/laravel-enum

Support us

We invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.

We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.

Usage

// a Laravel specific base class
use Spatie\Enum\Laravel\Enum;

/**

  • @method static self DRAFT()
  • @method static self PREVIEW()
  • @method static self PUBLISHED()
  • @method static self ARCHIVED()
  • / final class StatusEnum extends Enum {}

Model Attribute casting

Chances are that if you're working in a Laravel project, you'll want to use enums within your models. This package provides two custom casts and the

\Spatie\Enum\Laravel\Enum
also implements the
\Illuminate\Contracts\Database\Eloquent\Castable
interface.
use Illuminate\Database\Eloquent\Model;

class TestModel extends Model { protected $casts = [ 'status' => StatusEnum::class, 'nullable_enum' => StatusEnum::class.':nullable', 'array_of_enums' => StatusEnum::class.':collection', 'nullable_array_of_enums' => StatusEnum::class.':collection,nullable', ]; }

By using the casts the casted attribute will always be an instance of the given enum.

$model = new TestModel();
$model->status = StatusEnum::DRAFT();
$model->status->equals(StatusEnum::DRAFT());

Validation Rule

This package provides a validation rule to validate your request data against a given enumerable.

use Spatie\Enum\Laravel\Rules\EnumRule;

$rules = [ 'status' => new EnumRule(StatusEnum::class), ];

This rule validates that the value of

status
is any possible representation of the
StatusEnum
.

But you can also use the simple string validation rule definition:

$rules = [
    'status' => [
        'enum:'.StatusEnum::class,
    ],
];

If you want to customize the failed validation messages you can publish the translation file.

php artisan vendor:publish --provider="Spatie\Enum\Laravel\EnumServiceProvider" --tag="translation"

We pass several replacements to the translation key which you can use.

  • attribute
    - the name of the validated attribute
  • value
    - the actual value that's validated
  • enum
    - the full class name of the wanted enumerable
  • other
    - a comma separated list of all possible values - they are translated via the
    enums
    array in the translation file

Request Data Transformation

A common scenario is that you receive an enumerable value as part of yor request data. To let you work with it as a real enum object you can transform request data to an enum in a similar way to the model attribute casting.

Request macro

There is a request macro available which is the base for the other possible ways to cast request data to an enumerable.

$request->transformEnums($enumCastRules);

This is an example definition of all possible request enum castings. There are three predefined keys available as constants on

Spatie\Enum\Laravel\Http\EnumRequest
to cast enums only in specific request data sets. All other keys will be treated as independent enum casts and are applied to the combined request data set.
use Spatie\Enum\Laravel\Http\EnumRequest;

$enums = [ // cast the status key independent of it's data set 'status' => StatusEnum::class, // cast the status only in the request query params EnumRequest::REQUEST_QUERY => [ 'status' => StatusEnum::class, ], // cast the status only in the request post data EnumRequest::REQUEST_REQUEST => [ 'status' => StatusEnum::class, ], // cast the status only in the request route params EnumRequest::REQUEST_ROUTE => [ 'status' => StatusEnum::class, ], ];

You can call this macro yourself in every part of your code with access to a request instance. Most commonly you will do this in your controller action if you don't want to use one of the other two ways.

Form Requests

Form requests are the easiest way to cast the data to an enum.

use Illuminate\Foundation\Http\FormRequest;
use Spatie\Enum\Laravel\Http\Requests\TransformsEnums;
use Spatie\Enum\Laravel\Rules\EnumRule;

class StatusFormRequest extends FormRequest { use TransformsEnums;

public function rules(): array
{
    return [
        'status' => new EnumRule(StatusEnum::class),
    ];
}

public function enums(): array
{
    return [
        'status' => StatusEnum::class,
    ];
}

}

The request data transformation is done after validation via the

FormRequest::passedValidation()
method. If you define your own
passedValidation()
method you have to call the request macro
transformEnums()
yourself.
protected function passedValidation()
{
    $this->transformEnums($this->enums());

// ...

}

Middleware

You can also use the middleware to transform enums in a more general way and for requests without a form request.

use Spatie\Enum\Laravel\Http\Middleware\TransformEnums;

new TransformEnums([ 'status' => StatusEnum::class, ]);

Enum Make Command

We provide an artisan make command which allows you to quickly create new enumerables.

php artisan make:enum StatusEnum

You can use

--method
option to predefine some enum values - you can use them several times.

Faker Provider

It's very likely that you will have a model with an enum attribute and you want to generate random enum values in your model factory. Because doing so with default faker is a lot of copy'n'paste we've got you covered with a faker provider

Spatie\Enum\Laravel\Faker\FakerEnumProvider
. The static
register()
method is only a little helper - you can for sure register the provider the default way
$faker->addProvider(new FakerEnumProvider)
.

The faker methods itself are inherited from the base packages Faker Provider.
