Laravel verify locale in url is same as user's locale from database-CodePudding

So in my LocaleMiddleware class (which is located in the web group of the middleware), I have the following:

    if (Auth::check())
    {
        app()->setLocale($request->user()->getLocale()); // This just fetches the locale from the database for the given user
    }

And then it just returns the next request. However, there is a slight issue for example when logging in. I need to use the return redirect()->intended(); option. This poses a problem when I have for example the following route that I point to:

https://www.example.com/es/cervezas/dos

The English variant of this url would be:

https://www.example.com/en/beers/two

My routes look like this for example:

Route::name('user.')->prefix(app()->getLocale())->group(function () {
    Route::get(trans('routes.beers'), [BeersController::class, 'index'])->name('beers.index');
}

So in my routes I translate everything, and I also have slugs for each of my database models etc, which is why I always need to have the correct locale set but also I always need to have the correct locale in the url. If not I get not found exceptions when viewing specific model items or weird translations.

But one of the main problems is, when I go to the Spanish route for example (or any route for that matter in any language), after logging in, it will return the intended url/route, which will be the English one since en is the fallback locale.

So basically, what I was thinking is something along the lines of this, in my LocaleMiddleware class:

if (Auth::check())
{
    app()->setLocale($request->user()->getLocale());

    // Check if the segment locale is the same as the user locale
    // IF NOT, redirect them

    if(request()->segment(1) !== $request->user()->getLang())
    {
        return redirect()->route(request()->route()->getName()); // Not sure what to do here, doing this just creates an endless loop because the locale somehow was not updated yet it seems
    }
}

Any ideas for a solution for this, in the LocaleMiddleware or anywhere else? Or am I going about this the wrong way entirely? Any pointers are appreciated!

Edit:

Now in my LoginController I have the following:

protected function authenticated(Request $request, $user)
{
    app()->setlocale($user->getLocale());

    dd(app()->getLocale()); // This is the correct locale, `es` or `nl`

    dd(route('beers.index')); // This just always shows the English route
}

How come the app()->getLocale() shows the correct locale but the route is still always in the default locale? And of course, how to fix that?

CodePudding user response：

Usually you have access to the user in the login function before redirecting. In many of my projects there is an admin panel and I use the same default login endpoint. During the login process I check where the user is an admin or not and decide where to redirect him.

Here's an example of the store function in App\Http\Controllers\Auth\LoginController in a laravel 8 project:

/**
     * Handle an incoming authentication request.
     *
     * @param  \App\Http\Requests\Auth\LoginRequest  $request
     * @return \Illuminate\Http\RedirectResponse
     */
    public function store(LoginRequest $request)
    {
        $request->authenticate();

        $request->session()->regenerate();

        if (Auth::user()->hasRole('admin')) {
            return redirect()->intended(RouteServiceProvider::ADMIN_HOME);
        }

        return redirect()->intended(RouteServiceProvider::HOME);
    }

So I believe that if you edit your redirection logic in the login controller it should work, because you have access the user, before you actually redirect him.
