How to use Laravel multi-language features

Laravel is a full-stack framework that helps developers develop web applications, thereby simplifying the application development process. Language is one of the core parts of a web application because it helps you convey information to your users. Laravel supports multiple languages, so in this article, we will discuss how to set the language and show you how to use Laravel multilingual features.

First of all, let us understand the basic concepts of Laravel multi-language. Laravel provides a language file that contains all the text strings used in the application. These strings can be translated into other languages, so you can render different languages ​​in your application as needed. You can just use the translated string.

In Laravel, language files are stored in the resources/lang/ directory. This directory contains multiple subdirectories, each subdirectory corresponding to a language, for example: en corresponds to English, es corresponds to Spanish, etc. In each language directory, there is a messages.php file that contains all the strings for that language. If you need to add your own strings, add new strings to the messages.php file using the key-value pair format.

For example, we can add the following code in the messages.php file to define a simple welcome message:

'welcome' => 'Welcome to my website!',

Now, let's see how to set the language. In Laravel, you can use the app.php configuration file to set the default language of your application. This file is located in the config directory. Open the file and find the code like this:

'locale' => 'en',

The above code sets the default language of the application to English. If you want to set another language for your application, just change the above code to the target language. For example, if you want to set the default language of your application to Spanish, change the code to:

'locale' => 'es',

Now you can use Laravel's multilingual features to display translated text strings to the user. Let's look at a simple example using multiple languages.

Assume you have created a simple welcome page using Laravel. First, add the following code to the resources/views/welcome.blade.php file:

@extends('layouts.app')

@section('content')
    <h1 id="messages-welcome">{{ __('messages.welcome') }}</h1>
@endsection

In the above code, we use Laravel's __ function to present the welcome message. This function automatically looks up a string from the current language file and translates it into the appropriate language. In this example, we have defined a string named "welcome" in the messages.php file. Additionally, we use the @extends directive and the @section directive to extract the page layout and "content" section from the layouts/app.blade.php file.

Finally, we need to add multi-language support middleware to the application. Open the app/Http/Kernel.php file, find the web array under $middlewareGroups, and add \Illuminate\Foundation\Http\Middleware\SetLocale::class to the middleware array. Your code should look like this:

protected $middlewareGroups = [
    'web' => [
        // Other middleware...
        \Illuminate\Foundation\Http\Middleware\SetLocale::class,
    ],

    'api' => [
        // Other middleware...
    ],
];

After completing the above steps, you have successfully configured Laravel's multi-language functionality. You can easily add more languages ​​to your application and use the __ function to render text strings into any language you like.
