Manage your files with ease using a simple Shell Script.
Run one simple command to create all the needed folders, the only thing you need to do is upload you files in the correct folders.
As I wrote a piece about Localisation in Laravel 5.8, I decided to create a video tutorial about this.
So here it is.
In this tutorial we’re only focussing on localization, so I won’t go over the installation of Laravel and I assume that you already have a working Laravel project.
We are going to implement localization in 5 simple steps.
In the routes/web.php file you can find all the routes for your project, so we will also put our language route in this file.
I prefer to also put my language function in the route, by doing this we don’t need to have a LanguageController for this simple task.
Route::get('lang/{locale}', function ($locale) {
session()->put('locale', $locale);
return redirect()->back();
});
In this function we’re setting the locale in our App and also providing a locale variable to our session that we’re going to use in the next step.
In order to create this new Middleware we’ll run the following command in our terminal.
php artisan make:middleware LocalizationOnce this middleware is created by Artisan, we can find it in the app/Http/Middleware folder. To complete this middleware we’ll need to make some small changes to it, in order to get the behaviour we want. For starters we need to make sure it uses our App. this can be done by adding use App to it. We also need to make sure it sets the correct language. This can be done by setting the App locale value to what we have stored in our session.
The final result of this file should look like this.
namespace App\Http\Middleware;
use Closure;
use App;
class Localization
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
if (session()->has('locale')) {
App::setLocale(session()->get('locale'));
}
return $next($request);
}
}
In order to make the application use our newly created Localization Middleware we need to add it to the middelwaregroup. In the app/Http/Kernel.php file we need to add our Middleware class to the middlewareGroups.
The contents should then by like this.
protected $middlewareGroups = [
'web' => [
\App\Http\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
// \Illuminate\Session\Middleware\AuthenticateSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\App\Http\Middleware\VerifyCsrfToken::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
\App\Http\Middleware\Localization::class,
],
'api' => [
'throttle:60,1',
'bindings',
],
];
In the resources/lang folder there is a standard en folder, containing a few language files.
In this example we’re going to add our own language file to it called “customlang” and provide the following content to it.
return [
/*
|-------------------------------
| Custom Language Lines
|-------------------------------
*/
'welcome' => 'Welcome',
'chooselang' => 'Choose your language',
];
Now we can just make copy of the en folder and translate all content in it to a preferred language.
For example
return [
/*
|-------------------------------
| Custom Language Lines
|-------------------------------
*/
'welcome' => 'Welkom',
'chooselang' => 'Kies uw taal',
];
Now we’re able to use these custom translations in our views.
For example:
<div class="content">
<div class="title m-b-md">
{{__('customlang.welcome')}}
</div>
<p>{{__('customlang.chooselang')}}</p>
<div class="links">
<a href="lang/en">EN</a>
<a href="lang/nl">NL</a>
</div>
</div>
To add some extra flavour to it we can make use of a variable in our language file.
For example, we can add a username to our welcome message:
'welcome' => 'Welcome :user !',To make use of this we need to update our view as follows:
<div class="content">
<div class="title m-b-md">
{{__('customlang.welcome', [ 'user' => 'Bert'])}}
</div>
<p>{{__('customlang.chooselang')}}</p>
<div class="links">
<a href="lang/en">EN</a>
<a href="lang/nl">NL</a>
</div>
</div>
