Installation

composer require shammaa/laravel-translations

Publish configuration and migrations:

php artisan vendor:publish --tag=translations-config
php artisan vendor:publish --tag=translations-migrations
php artisan migrate

Quick Start

1. Add Trait to Your Model

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Shammaa\LaravelTranslations\Traits\IsTranslatable;

class Article extends Model
{
    use IsTranslatable;

    protected $translatable = ['title', 'slug', 'content', 'description'];
    
    // ✅ The model automatically follows app()->getLocale() (site locale)!
    // ❌ Don't use $translationLocale - it's deprecated and ignored!
}

2. Set Locale in Middleware (Auto-follow site locale)

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;

class SetLocale
{
    public function handle(Request $request, Closure $next)
    {
        // Detect locale from URL, session, etc.
        $locale = $request->segment(1) ?? session('locale', 'ar');
        
        if (in_array($locale, ['ar', 'en'])) {
            app()->setLocale($locale);
        }
        
        return $next($request);
    }
}

Now the model automatically follows the site locale! ✅

2. Use It!

// Create with translation
$article = Article::create(['status' => 1]);

// Translate (uses current locale automatically!)
$article->translateTo([
    'title' => 'Article Title',
    'slug' => 'article-slug',
    'content' => 'Article content...',
])->save();

// Access translations (auto-detects current locale)
app()->setLocale('en');
echo $article->title; // "Article Title" ✅

app()->setLocale('ar');
echo $article->title; // "عنوان المقال" ✅

// Set locale for this instance (overrides app locale)
$article->setLocale('ar');
echo $article->title; // "عنوان المقال" ✅


// Query
$articles = Article::whereTranslationLike('title', 'Laravel')->get();

Usage Examples

Multiple Languages Support

Option 1: Dynamic (Recommended - follows app locale)

// In Model - don't set translationLocale
class Article extends Model
{
    use IsTranslatable;
    protected $translatable = ['title', 'slug', 'content'];
    // No translationLocale - automatically follows app()->getLocale()
}

// Usage
app()->setLocale('en');
echo $article->title; // "Article Title" ✅

app()->setLocale('ar');
echo $article->title; // "عنوان المقال" ✅

Option 2: translationLocale property (Deprecated - DON'T USE!)

// ⚠️ DON'T USE THIS! This property is deprecated and ignored.
// The model ALWAYS follows app()->getLocale() automatically.
// ❌ Don't use: protected $translationLocale = '...'; 

// Just remove it - the model will work perfectly without it:
class Article extends Model
{
    use IsTranslatable;
    protected $translatable = ['title', 'slug', 'content'];
    // No translationLocale needed! ✅ The model follows app()->getLocale() automatically!
}

// Usage - ALWAYS follows app locale automatically!
app()->setLocale('en');
echo $article->title; // "Article Title" ✅ (follows site locale!)

app()->setLocale('ar');
echo $article->title; // "عنوان المقال" ✅ (follows site locale!)

Option 3: Dynamic per instance

$article->setLocale('ar');
echo $article->title; // "عنوان المقال" ✅

$article->setLocale('en');
echo $article->title; // "Article Title" ✅

Priority order: setLocale() > app()->getLocale() (site locale) ALWAYS!

Important:

• ✅ The model ALWAYS follows the site locale (app()->getLocale()) automatically!
• ❌ Don't use $translationLocale property - it's deprecated and completely ignored!
• ✅ Just set the locale in your middleware/controller: app()->setLocale('ar') or app()->setLocale('en')
• ✅ The model will automatically use the current site locale - no configuration needed!

Saving Translations

// Single locale (auto-detects current locale)
$article->translateTo([
    'title' => 'Article Title',
    'slug' => 'article-slug',
])->save();

// Multiple locales
$article->fillTranslations([
    'ar' => ['title' => 'عنوان المقال', 'slug' => 'maqal'],
    'en' => ['title' => 'Article Title', 'slug' => 'article'],
])->save();

Querying

// Search in translations
Article::whereTranslationLike('title', 'Laravel')->get();

// Filter by translation availability
Article::hasTranslation('en')->get();
Article::missingTranslation('fr')->get();

// Eager load translations
Article::withTranslations(['ar', 'en'])->get();

Advanced Features

// Check missing fields
$missing = $article->getMissingFields('en');

// Get translation completion
$percentage = $article->getTranslationCompletion('en'); // 75.5%

// Clone translations
$article->cloneTranslations('ar', 'en')->save();

// Get statistics
$stats = Article::translationStats();
// ['ar' => 1000, 'en' => 800]

Performance

The package is highly optimized:

• Single item: 0.1-1ms (with cache)
• 100 items: 50-100ms
• 1000 items: 400-600ms
• 15-50x faster than key-value approach
• 99% fewer queries

Run benchmark:

php artisan translations:benchmark --model="App\Models\Article" --count=100

Configuration

Edit config/translations.php:

'default_locale' => 'ar',
'supported_locales' => ['ar', 'en', 'fr'],
'searchable_fields' => ['title', 'slug', 'description', ...],
'large_fields' => ['content', 'body', ...],
'cache' => [
    'enabled' => true,
    'ttl' => 3600,
],

Testing

Run the test suite:

composer test
# or
vendor/bin/phpunit

The package includes:

• ✅ Unit tests for validation and exceptions
• ✅ Integration tests for trait functionality
• ✅ Full test coverage
