I am trying to set the language in my app dynamically, based on users stored language. I am storing the language of the user in the users db. I am using the mcamara/laravel-localization package. So far I tried it with a middleware to set the language of the user but no success.
Middleware
if($user = Auth::user()) {
App::setLocale($user->lang);
LaravelLocalization::setLocale($user->lang);
}
return $next($request);
The problem is the url does not have the lang code in the url.
In app.blade.php, in the beginning:
<!DOCTYPE html>
<html lang="{{ app()->getLocale() }}">
In this case, app()->getLocale() should return a string like en-EN or de-DE
If app()->getLocale() returns string like en_EN, de_DE and so on, you can use:
<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
Also, you can take a look of this package: https://github.com/amiranagram/localizator. I find it easier to use.
@Merklin Thanks for your answer, will have a look :)
This is already in my app.blade.php because I am using breeze.
<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
The problem is I can't generate the right urls based on the users stored language.
I don't know your exact configuration, as I'm not familiar with this package, but this is my middleware:
public function handle(Request $request, Closure $next): Response
{
if (
isset(auth()->user()->language)
&& auth()->user()->language
&& array_key_exists(auth()->user()->language, Config::get('languages'))
) {
if (session()->has('applocale') && array_key_exists(session()->get('applocale'), config('languages'))) {
App::setLocale(session()->get('applocale'));
} else {
Session::put('applocale', auth()->user()->language);
}
}
if (session()->has('applocale') && array_key_exists(session()->get('applocale'), config('languages'))) {
App::setLocale(session()->get('applocale'));
} else { // This is optional as Laravel will automatically set the fallback language if there is
// none specified
App::setLocale(config('app.fallback_locale'));
}
return $next($request);
}
At the bottom of routes/web.php
Route::get('lang/{lang}', [LanguageController::class, 'switchLang'])->name('lang.switch');
The Controller:
final class LanguageController extends Controller
{
public function switchLang(string $lang): RedirectResponse
{
if (array_key_exists($lang, Config::get('languages'))) {
Session::put('applocale', $lang);
}
return Redirect::back();
}
}
@Merklin Thanks for you detailed answer but I think with my package this will not work.
Tried it like so
public function handle(Request $request, Closure $next): Response
{
if ($request->user()) {
return redirect()->to(LaravelLocalization::getLocalizedURL($request->user()->lang, route($request->route()->getName()), [], true));
}
return $next($request);
}
I get the error too many redirects. I have to somehow force the db lang, but dont know how.
I think it is working now. What I have done is the following
public function handle(Request $request, Closure $next): Response
{
if ($user = Auth::user()) {
App::setLocale($user->lang);
Session::put('locale', $user->lang);
LaravelLocalization::setLocale($user->lang);
}
return $next($request);
}
Seems to work.
