How to Create Multilingual Translated Routes in Laravel

Introduction

Translating routes is essential for creating multilingual applications. In Laravel, it's possible to have multiple languages and dynamically switch the language based on the URL. This article explains how to implement multilingual translated routes in Laravel using the first method outlined in the reference article.

Step 1: Translate Routes

Create three routes.php files in the app/lang directory for each language (e.g., pl/routes.php, en/routes.php, and fr/routes.php). Inside each file, translate the route names:

• Polish:

<code class="php"><?php
// app/lang/pl/routes.php

return array(

    'contact' => 'kontakt',
    'about' => 'o-nas'
);</code>

• English:

<code class="php"><?php
// app/lang/en/routes.php

return array(
    'contact' => 'contact',
    'about' => 'about-us'
);</code>

• French:

<code class="php"><?php
// app/lang/fr/routes.php

return array(
    'contact' => 'contact-fr',
    'about' => 'about-fr'
);</code>

Step 2: Configure Language Settings

Update the app/config/app.php file:

• Set the primary language:

<code class="php">'locale' => 'pl',</code>

• List the alternative languages:

<code class="php">'alt_langs' => array('en', 'fr'),</code>

• Define the locale prefix:

<code class="php">'locale_prefix' => '',</code>

Step 3: Define Route Patterns

In app/routes.php, set up route patterns based on the language translations:

<code class="php"><?php
// app/routes.php

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

Step 4: Group Routes by Locale

Create a route group with a prefix equal to the selected locale:

<code class="php"><?php
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 5: Handle Redirects

In app/start/global.php, create a 301 redirection for unknown URLs to the correct language:

<code class="php"><?php
// app/start/global.php

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