How to Create Multilingual Translated Routes in Laravel?

Creating Multilingual Translated Routes in Laravel

In Laravel applications, you can create multilingual routes that depend on the selected language, allowing for a user-friendly navigation experience.

Step 1: Configure Language Directories and Translations

Create three separate language directories under app/lang (e.g., pl, en, fr). In each directory, create a file named routes.php that contains the translated route names:

<code class="php">// app/lang/pl/routes.php
return array(
    'contact' => 'kontakt',
    'about' => 'o-nas'
);</code>

<code class="php">// app/lang/en/routes.php
return array(
    'contact' => 'contact',
    'about' => 'about-us'
);</code>

<code class="php">// app/lang/fr/routes.php
return array(
    'contact' => 'contact-fr',
    'about' => 'about-fr'
);</code>

Step 2: Configure Language Settings

In app/config/app.php:

• Set 'locale' to your default language (e.g., 'pl').
• Include the list of alternative languages in 'alt_langs' (e.g., ['en', 'fr']).
• Leave 'locale_prefix' empty for the default language prefix.

<code class="php">'locale' => 'pl',
'alt_langs' => ['en', 'fr'],
'locale_prefix' => '',</code>

Step 3: Define Route Patterns and Language-Dependent Group

In app/routes.php:

• If the first segment of the URL matches an alternative language, update the locale and locale_prefix.
• Set route patterns based on the current language translations.
• Create a route group with the language prefix applied.

<code class="php">if (in_array(Request::segment(1), Config::get('app.alt_langs'))) {

    App::setLocale(Request::segment(1));
    Config::set('app.locale_prefix', Request::segment(1));
}

foreach(Lang::get('routes') as $k => $v) {
    Route::pattern($k, $v);
}

Route::group(array('prefix' => Config::get('app.locale_prefix')), function() {

    Route::get('/', function () {
        return "main page - ".App::getLocale();
    });

    Route::get('/{contact}/', function () {
        return "contact page ".App::getLocale();
    });

    Route::get('/{about}/', function () {
        return "about page ".App::getLocale();
    });

});</code>

Step 4: Handle Unknown URLs

In app/start/global.php:

• Redirect any unknown URLs to the correct language prefix with a 301 status code:

<code class="php">App::missing(function() {
   return Redirect::to(Config::get('app.locale_prefix'), 301);
});</code>

By implementing these steps, you will create dynamic routes that adapt to the selected language, ensuring a seamless user experience across multiple languages.
