Laravel Localized Enum

A Laravel package that provides automatic localization support for PHP enums, making it easy to display translated enum values in your application.

Installation

You can install the package via Composer:

composer require domthomas-dev/laravel-localized-enum

The package will automatically register its service provider.

Configuration

Optionally, you can publish the configuration file:

php artisan vendor:publish --tag=localized-enum-config

This will create a config/localized-enum.php file where you can customize:

return [
    // Default label type when none is specified
    'default_label' => 'label',
    
    // Translation file name (without .php extension)
    'translation_file' => 'enums',
];

Usage

Basic Usage

Add the LocalizedEnum trait to your enum:

<?php

namespace App\Enums;

use DomThomas\LocalizedEnum\LocalizedEnum;

enum ContactType: string
{
    use LocalizedEnum;

    case EMAIL = 'email';
    case PHONE = 'phone';
    case SMS = 'sms';
}

Translation Files

Create translation files for your enums in your resources/lang directory:

// resources/lang/en/enums.php
<?php

use App\Enums\ContactType;

return [
    ContactType::class => [
        'label' => [
            ContactType::EMAIL->name => 'Email',
            ContactType::PHONE->name => 'Phone',
            ContactType::SMS->name => 'SMS',
        ],
        'description' => [
            ContactType::EMAIL->name => 'Send via email',
            ContactType::PHONE->name => 'Call by phone',
            ContactType::SMS->name => 'Send text message',
        ],
    ],
];

// resources/lang/fr/enums.php
<?php

use App\Enums\ContactType;

return [
    ContactType::class => [
        'label' => [
            ContactType::EMAIL->name => 'E-mail',
            ContactType::PHONE->name => 'Téléphone',
            ContactType::SMS->name => 'SMS',
        ],
        'description' => [
            ContactType::EMAIL->name => 'Envoyer par e-mail',
            ContactType::PHONE->name => 'Appeler par téléphone',
            ContactType::SMS->name => 'Envoyer un SMS',
        ],
    ],
];

Getting Labels

$contact = new Contact();
$contact->type = ContactType::EMAIL;

// Get default label
echo $contact->type->label(); // "Email"

// Get label in specific locale
echo $contact->type->label(locale: 'fr'); // "E-mail"

Multiple Label Types

You can define multiple label types for the same enum as shown in the translation files above:

// Get description label
echo ContactType::EMAIL->label('description'); // "Send via email"

// Get default label (uses 'label' key)
echo ContactType::EMAIL->label(); // "Email"

For Select Inputs

Generate arrays suitable for HTML select inputs:

// Get all options for select
$options = ContactType::forSelect();
// Returns: ['email' => 'Email', 'phone' => 'Phone', 'sms' => 'SMS']

// With placeholder
$options = ContactType::forSelect(placeHolder: 'Choose contact type');
// Returns: ['' => 'Choose contact type', 'email' => 'Email', 'phone' => 'Phone', 'sms' => 'SMS']

// With specific label type
$options = ContactType::forSelect(label: 'description');
// Returns: ['email' => 'Send via email', 'phone' => 'Call by phone', 'sms' => 'Send text message']

// With specific locale
$options = ContactType::forSelect(locale: 'fr');
// Returns: ['email' => 'E-mail', 'phone' => 'Téléphone', 'sms' => 'SMS']

// Exclude specific cases
$options = ContactType::forSelect(excepted: [ContactType::SMS]);
// Returns only EMAIL and PHONE options
// Returns: ['email' => 'Email', 'phone' => 'Phone']

// Include only specific cases
$options = ContactType::forSelect(only: [ContactType::EMAIL, ContactType::PHONE]);
// Returns only EMAIL and PHONE options
// Returns: ['email' => 'Email', 'phone' => 'Phone']


// Get structured options array
$options = ContactType::options();
// Returns: [
//     ['value' => 'email', 'label' => 'Email'],
//     ['value' => 'phone', 'label' => 'Phone'],
//     ['value' => 'sms', 'label' => 'SMS']
// ]

// With custom label and locale
$options = ContactType::options(label: 'description', locale: 'fr');

Blade Usage

<!-- In a select input -->
<select name="contact_type">
    @foreach(ContactType::forSelect(placeHolder: 'Select type') as $value => $label)
        <option value="{{ $value }}">{{ $label }}</option>
    @endforeach
</select>

<!-- Select with filtered options -->
<select name="preferred_contact">
    @foreach(ContactType::forSelect(placeHolder: 'Choose method', excepted: [ContactType::SMS]) as $value => $label)
        <option value="{{ $value }}">{{ $label }}</option>
    @endforeach
</select>

<!-- Display enum label -->
<p>Contact type: {{ $contact->type->label() }}</p>
<p>Description: {{ $contact->type->label('description') }}</p>

Translation Key Format

The package automatically generates translation keys using this format:

{translation_file}.{EnumClass}.{label_type}.{case_name}

For example (with default config):

• App\Enums\ContactType::EMAIL → enums.App\Enums\ContactType.label.EMAIL
• With description: enums.App\Enums\ContactType.description.EMAIL

You can customize the translation file name and default label type in the configuration.

Utility Methods

// Get all enum values as array
$values = ContactType::values();
// Returns: ['email', 'phone', 'sms']

// Filter enum cases
$filtered = ContactType::filterCases(excepted: [ContactType::SMS]); // Exclude SMS
$onlyEmailPhone = ContactType::filterCases(only: [ContactType::EMAIL, ContactType::PHONE]); // Only EMAIL and PHONE

Advanced Features

Fallback Behavior

If a translation key is not found, the package will fall back to the enum case name:

// If translation doesn't exist, returns the case name
echo ContactType::EMAIL->label(); // "EMAIL" (if no translation found)

Translation Structure

The translation structure uses the enum class as the top-level key in your translation files (default: resources/lang/{locale}/enums.php):

use App\Enums\ContactType;

return [
    ContactType::class => [
        'label' => [
            ContactType::EMAIL->name => 'Email',
            ContactType::PHONE->name => 'Phone',
        ],
        'description' => [
            ContactType::EMAIL->name => 'Send via email',
            ContactType::PHONE->name => 'Call by phone',
        ],
        // You can add custom label types
        'short' => [
            ContactType::EMAIL->name => 'E',
            ContactType::PHONE->name => 'P',
        ],
    ],
];

Note: If you change the translation_file config to something other than 'enums', make sure to update your file names accordingly (e.g., translations.php if you set it to 'translations').
