Introduction to Laravel Localization
In today’s globalized world, reaching a wider audience is crucial for any successful web application. Laravel localization, also known as internationalization (i18n) and localization (l10n), enables you to build applications that support multiple languages. This guide provides a comprehensive, beginner-friendly introduction to implementing laravel localization in your projects. We’ll cover everything from setting up your language files to displaying translated content in your views.
Why Laravel Localization is Important
Building a multi-language application offers numerous benefits:
- Wider Reach: Target users who prefer content in their native language.
- Improved User Experience: Provide a more personalized and engaging experience.
- Increased Conversions: Users are more likely to interact with content they understand.
- Enhanced SEO: Optimize your application for different language-specific keywords.

Setting Up Your Laravel Project for Localization
First, ensure your Laravel project is properly set up. Then, we’ll focus on the configuration files that control how laravel localization works. The primary file is located at config/app.php. Look for the 'locale' and 'fallback_locale' keys.
// config/app.php
'locale' => 'en',
'fallback_locale' => 'en',
The 'locale' determines the default language of your application. The 'fallback_locale' specifies the language to use if a translation isn’t found for the current locale.
Creating Language Files
Laravel stores language translations in the resources/lang directory. Create a new directory for each language you want to support. For example, to support Spanish, create a resources/lang/es directory. Inside each language directory, create PHP files containing your translations. Conventionally, use filenames that describe the content they translate, such as messages.php or auth.php.
// resources/lang/en/messages.php
return [
'welcome' => 'Welcome to our application!',
'greeting' => 'Hello, :name!',
];
// resources/lang/es/messages.php
return [
'welcome' => '¡Bienvenido a nuestra aplicación!',
'greeting' => '¡Hola, :name!',
];
Implementing Laravel Localization in Your Views
To display translated content in your views, use the __() helper function or the @lang directive. The __() helper function takes a key as an argument and returns the corresponding translation from the language files.
// Example using the __() helper function
<p></p>
// Example using the @lang directive (Blade template)
<p>@lang('messages.welcome')</p>
You can also pass variables to your translations using placeholders:
// In your language file:
'greeting' => 'Hello, :name!',
// In your view:
<p> $user->name]); ?></p>
Changing the Application Locale
To switch the application locale, use the App::setLocale() method. This method sets the current locale for the application.
use IlluminateSupportFacadesApp;
App::setLocale('es'); // Sets the locale to Spanish
Typically, you’ll want to allow users to select their preferred language. This can be achieved through a language switcher in your application’s interface. Store the user’s preferred language in their session or profile and then use middleware to set the locale based on their preference.
Middleware for Setting the Locale
Create a middleware to automatically set the locale based on user preferences. For example, if a user has their preferred language saved in their session, you can retrieve it and set the locale.
// app/Http/Middleware/SetLocale.php
namespace AppHttpMiddleware;
use Closure;
use IlluminateSupportFacadesApp;
use IlluminateSupportFacadesSession;
class SetLocale
{
public function handle($request, Closure $next)
{
if (Session::has('locale')) {
App::setLocale(Session::get('locale'));
}
return $next($request);
}
}
Remember to register the middleware in your app/Http/Kernel.php file.
Laravel Localization Package Suggestions
While Laravel provides built-in localization features, several packages can simplify the process and offer additional functionality.
- mcamara/laravel-localization: A popular package that provides a route-based approach to localization, allowing you to define different routes for each language. More information can be found here: mcamara/laravel-localization on GitHub
Database Translations
For dynamic content stored in your database, you’ll need a strategy for handling translations. There are several approaches:
- Separate Columns: Create separate columns for each language in your database table (e.g.,
title_en,title_es). - JSON Columns: Store translations in a JSON column, with each language as a key.
- Dedicated Translation Tables: Create separate tables to store translations for each record.
The best approach depends on the complexity of your application and the amount of translatable content. For simpler applications, separate columns might suffice. For more complex scenarios, dedicated translation tables offer more flexibility.
Laravel Localization Best Practices
- Use consistent keys: Establish a clear naming convention for your translation keys.
- Test your translations: Thoroughly test your application in different languages to ensure accuracy.
- Consider using a translation management service: Services like Phrase or Lokalise can help you manage your translations more efficiently. Learn more about services like Phrase.
- Store user’s locale: Remember to store the user’s preferred language in a cookie, session, or database to maintain consistency across sessions.
SEO Considerations for Multi-Language Sites
When implementing laravel localization, consider the impact on your website’s SEO. Here are some key points:
- Use hreflang tags: Implement hreflang tags to tell search engines which language versions of your pages are intended for which regions/languages.
- Use language-specific URLs: Use different URLs for each language version of your site (e.g.,
/en/,/es/). - Translate metadata: Translate your page titles, meta descriptions, and other metadata to improve search engine rankings in each language.
