Elegant Enum implementation for Laravel

This package is fork of removed one https://github.com/mad-web/laravel-enum.git

This package is not supported. Please switch to php enum.

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',
];

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

// or check one of multiple values
