Multi Language
Multi Language Settings
Laravel's localization features provide a convenient way to retrieve strings in various languages, allowing you to easily support multiple languages within your application. Typically, translation strings are stored in files within the resource/lang directory. Within this directory, there should be a subdirectory for each language supported by your application. This is the approach Laravel uses to manage translation strings for built-in Laravel features such as validation error messages:
All language files return an array of keyed strings. For example.
<?php
// resource/lang/en/messages.php
return [
'welcome' => 'Welcome to doctorly laravel!',
];
Retrieving Translation Strings.
You may retrieve translation strings from your language files using the __ helper function. If you are using "short keys" to define your translation strings, you should pass the file that contains the key and the key itself to the __ function using "dot" syntax. For example, let's retrieve the welcome translation string from the resource/lang/en/translation.php language file:
echo __('translation.welcome');
If you are using the Blade templating engine, you may use the {{ }} syntax to echo the translation string or use the @lang directive:
{{ __('translation.welcome') }}
@lang('translation.welcome')
Let's add the French language.
To add a new language in whole template first we need to create a translation.php file in resource/lang which return an array with key and value pair.
Now you need to add the language in the resources/view/layouts/top-hor.blade.php file. add the "case" condition as below code and make sure to add the french.jpg file in the public/assets/images/flags folder.
@case('ru'){
<img src="{{ URL::asset('/assets/images/flags/french.svg')">
}
You can simply use @lang attributes in the HTML tag to convert the language text. Example: <a href="#">@lang('translation.title')</a>
Add the below dropdown in the resources/view/layouts/top-hor.blade.php file in the language dropdown.
<a href="{{ url('index/fr') }}" class="dropdown-item notify-item language" data-lang="sp" title="French">
<img src="{{ URL::asset('/assets/images/flags/french.jpg') }}" alt="user-image" class="me-2 rounded" height="18">
<span class="align-middle">French</span>
</a>
Localization in Doctorly
In Doctorly laravel, We provide a dropdown to switch language you can find it in the top-bar. How does it work? When we select a language from dropdown-menu we call a Route which calls a controller's function which then put selected language in session. We have created a middleware that sets the localization value from the session variable. It sounds a little messy. Let's find out how to do it.
Use the below code in HomeController file in App/Http/Controllers.
public function lang($locale)
{
if ($locale) {
App::setLocale($locale);
Session::put('lang', $locale);
Session::save();
return redirect()->back()->with('locale', $locale);
} else {
return redirect()->back();
}
}
We have to define Route for language switching in routes/web.php file.
<?php
use App\Http\Controllers\HomeController;
// locale Route
Route::get('index/{locale}', [App\Http\Controllers\HomeController::class, 'lang']);
Now we need a middleware to set app()->setLocale() variable gloabaly. Run below cammand to create a middleware.
php artisan make:middleware Localization
You can find this middleware in App\Http\Middleware.
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\App;
class Localization
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle(Request $request, Closure $next)
{
/* Set new lang with the use of session */
if (session()->has('lang')) {
App::setLocale(session()->get('lang'));
}
return $next($request);
}
}
You must have to mention middleware in the App\Http\kernel.php file. Use the \App\Http\Middleware\LocaleMiddleware::class, line in kernel.php file.
protected $middlewareGroups = [
'web' => [
\App\Http\Middleware\Localization::class,
],
Now we have to set the view. We provide language switch dropdown in top-hor.blade.php.
<div class="dropdown d-inline-block">
<button type="button" class="btn header-item noti-icon waves-effect"
data-bs-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
@switch(Session::get('lang'))
@case('ru')
<img src="{{ URL::asset('/assets/images/flags/russia.svg') }}" class="rounded" alt="Header Language"
height="20">
@break
@case('it')
<img src="{{ URL::asset('/assets/images/flags/italy.svg') }}" class="rounded" alt="Header Language"
height="20">
@break
@default
<img src="{{ URL::asset('/assets/images/flags/us.svg') }}" class="rounded" alt="Header Language" height="20">
@endswitch
</button>
<div class="dropdown-menu dropdown-menu-end">
<!-- item-->
<a href="{{ url('index/en') }}" class="dropdown-item notify-item language py-2" data-lang="en"
title="English">
<img src="{{ URL::asset('assets/images/flags/us.svg') }}" alt="user-image" class="me-2 rounded" height="20">
<span class="align-middle">English</span>
</a>
<!-- item-->
<a href="{{ url('index/sp') }}" class="dropdown-item notify-item language" data-lang="sp"
title="Spanish">
<img src="{{ URL::asset('assets/images/flags/spain.svg') }}" alt="user-image" class="me-2 rounded" height="20">
<span class="align-middle">Española</span>
</a>
</div>
</div>
Include the newly created switcher into the new file view: filename.blade.php
<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
<title> @lang('translation.welcome')</title>
</head>
</html>
In the Resources/views/layouts file hor-menu.blade.php
<li class="nav-item">
<div class="collapse navbar-collapse" id="topnav-menu-content">
<ul class="nav nav-sm flex-column">
<li class="nav-item">
<a href="apps-crm-contacts" class="nav-link" >@lang('translation.contacts')</a>
</li>
<li class="nav-item">
<a href="apps-crm-companies" class="nav-link" >@lang('translation.companies')</a>
</li>
<li class="nav-item">
<a href="apps-crm-deals" class="nav-link" >@lang('translation.deals')</a>
</li>
<li class="nav-item">
<a href="apps-crm-leads" class="nav-link" >@lang('translation.leads')</a>
</li>
</ul>
</div>
</li>
