Elegant Enum implementation for Laravel

Based on MyCLabs PHP Enum and implements SplEnum interface.

You could find documentation for base features in PHP Enum Readme.

Features:

• make:enum command
• ability to cast enum fields for Eloquent models
• labels translation via lang files
• simple validation rule

Simple Enum Example

namespace App\Enums;

use MadWeb\Enum\Enum;

/**
 * @method static PostStatusEnum FOO()
 * @method static PostStatusEnum BAR()
 * @method static PostStatusEnum BAZ()
 */
final class PostStatusEnum extends Enum
{
    const __default = self::PENDING;

    const PUBLISHED = 'published';
    const PENDING = 'pending';
    const DRAFT = 'draft';
}

Installation

For Laravel < 7 version - use 1.0 branch.

You can install the package via composer:

composer require mad-web/laravel-enum

Usage

Make new Enum class via artisan command:

php artisan make:enum PostStatusEnum

to populate Enum with your own values, pass it after name argument:

php artisan make:enum PostStatusEnum DRAFT=draft PENDING=pending PUBLISHED=published

Create instance of Enum class

$status = new PostStatusEnum(PostStatusEnum::PENDING);

// or just use magic static method
$status = PostStatusEnum::PENDING();

Enums support native Custom Casts feature out of the box. Specify Enum class for attribute in $casts array:

class Post extends Model
{
    protected $fillable = ['title', 'status'];

    protected $casts = [
        'status' => PostStatusEnum::class,
    ];
}

after that you could get and set enum field using enum classes

$post = Post::first();

$status = $post->status; // PostStatusEnum

$post->status = PostStatusEnum::PENDING();

$post->save();

Enum values labels (Localization)

Create enums.php lang file and declare labels for enum values

// resources/lang/en/enums.php

return [
    PostStatusEnum::class => [
        PostStatusEnum::PENDING => 'Pending Label',
        PostStatusEnum::PUBLISHED => 'Published Label',
        PostStatusEnum::DRAFT => 'Draft Label',
    ],
];

and get a label

PostStatusEnum::PENDING()->label(); // Pending Label

To override default enum lang file path, publish laravel-enum config

php artisan vendor:publish --provider=MadWeb\\Enum\\EnumServiceProvider

and change lang_file_path option

// config/enum.php

return [
    'lang_file_path' => 'custom.path.to.enums',
];

Validation Rule

You may validate an enum value from a request by using the EnumRule class or Enum::rule() method.

public function store(Request $request)
{
    $this->validate($request, [
        'status' => ['required', new EnumRule(PostStatusEnum::class)],
    ]);

    // OR

    $this->validate($request, [
        'status' => ['required', PostStatusEnum::rule()],
    ]);
}

If you want to validate an enum key instead of an enum value you can by specifying you want to validate against the key instead of the value.

public function store(Request $request)
{
    $this->validate($request, [
        'status' => ['required', new EnumRule(PostStatusEnum::class, true)],
    ]);

    // OR

    $this->validate($request, [
        'status' => ['required', PostStatusEnum::ruleByKey()],
    ]);
}

To customize validation message, add enum key to validation lang file

// resources/lang/en/validation.php
return [
    //...
    'enum' => 'Custom validation message form enum attribute :attribute',
];

Additional methods

getRandomKey(): string

Returns a random key from the enum.

PostStatusEnum::getRandomKey(); // Returns 'PUBLISHED` or `PENDING` or `DRAFT`

getRandomValue()

Returns a random value from the enum.

PostStatusEnum::getRandomValue(); // Returns 'published` or `pending` or `draft`

label(): string

Returns label for the enum value object

PostStatusEnum::PUBLISHED()->label(); // Returns 'published` or custom label declared in a lang file

labels(): array

Returns all labels for a enum

PostStatusEnum::labels(); // Returns ['published`, 'pending', 'draft'] or array of custom labels declared in a lang file

is($value): bool

Checks whether the current enum value is equal to a given enum

$status = PostStatusEnum::PENDING();


PostStatusEnum::PUBLISHED()->is($status); // false

PostStatusEnum::PENDING()->is($status); // true

// or

PostStatusEnum::PUBLISHED()->is($status->getValue()); // false

PostStatusEnum::PENDING()->is($status->getValue()); // true

// or check one of multiple values

$status->is([PostStatusEnum::DRAFT(), PostStatusEnum::PUBLISHED()]) // false

$status->is([PostStatusEnum::DRAFT(), PostStatusEnum::PENDING()]) // true

rule(): EnumRule

Returns instance of validation rule class for the Enum

PostStatusEnum::rule(); // new EnumRule(PostStatusEnum::class);
