Redirect back to same page after changing locale

The way I implemented multilang is through middleware and routes.

Middleware Localization.php looks like this:

    public function handle(Request $request, Closure $next)
    {
        $locale = $request->segment(1); 


        if(empty($locale)) { 
            return redirect()->to('/' . app()->getLocale());
        }

        if(in_array($locale, ['en','it'])) {
            App::setLocale($locale);
            $request->except(0); 
        }

        return $next($request);
    }

And in my web.php I have:

Route::get('locale/{locale}', function ($locale){
    \Session::put('locale', $locale);
    $path = Route::getCurrentRoute()->getPath();

    return redirect($path);
})->name('langroute');

In blade I'm using it like this:

<a class="dropdown-item" href="{{ url('/en') }}">

How can I redirect back to same page after changing to another lang?

I tried achieving that using Route:: helper but the problem is on the pages that have parameters.

<a class="dropdown-item" href="{{ route(Route::currentRouteName(), 'en') }}">

But it throws this error:

Missing required parameters for [Route: frontend.category] [URI: {locale}/{slug}]. (View: /var/www/html/project/resources/views/frontend/layouts/header.blade.php).

I cannot put parameters since the language switcher is on header and the parameters are different and many...

Any help would be appreciated!

i almost understand you issue but let me know of i'm wrong, I did it in the blade view as following

    <?php
        $thisUrl = url()->current().'/';
        if (app()->getlocale() == 'en') {
            $newUrl  = str_replace('/en/', '/it/', $thisUrl);
        }else{
            $newUrl  = str_replace('/it/', '/en/', $thisUrl);
        }
     ?>

if you are just using two langs you may share a global variable to all of your views as following in your AppServiceProvider

<?php

namespace App\Providers;

use Illuminate\Support\Facades\View;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }

    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        $thisUrl = url()->current().'/';
        if (app()->getlocale() == 'en') {
            $newUrl  = str_replace('/en/', '/it/', $thisUrl);
        }else{
            $newUrl  = str_replace('/it/', '/en/', $thisUrl);
        }
        View::share('newUrl', $newUrl);
    }
}

then in your Blade View

<a class="dropdown-item" href="{{ $newUrl }}">

Sorry for the late response @khaledw62 but once we get off the office we cannot access remotely our projects from home.

Let me give a try and I will tell you.

Brother thank you very much because that worked for me. That is a very simple and good solution to my problem. May God bless you!

I'm sure that many will benefit from your answer about redirecting back with locale because in 3 days no one could give me correct answer in several forums.

Again, thank you!

@khaledw62 I have another question related to my question even that the problem is already solved.

In case that in future I add other language like de and others languages as well, how can I manage it in that case.

Magalliu's avatar

Thanks for the suggestion @michaloravec , I know about mcamara package but the problem is that I have already completed the project and that was the last bug to fix. And I don't know how it will affect the project starting over with localization using mcamara package...

khaledw62's avatar

if you want a work around but it will be handy,

        $thisUrl = url()->current().'/';
        $appLocale = app()->getlocale();
        
        //Lets Say You Have Array of Languages
        $langs = ['en','it','de','es'];
        
        //Remove the current Language Url
        unset($langs[$appLocale]);
        //Generating Urls For All of Your Languages
        $urls = [];
        foreach ($langs as $lang) {
            $urls[$langs] = str_replace('/' . $appLocale . '/', '/' . $lang . '/', $thisUrl);
        }

Thanks again @khaledw62.

Look I was testing and in first place all seems good but there is a problem with AppServiceProvider solution and I can't understand why.

$thisUrl = url()->current().'/';
        if (app()->getlocale() == 'en') {
            $newUrl  = str_replace('/en/', '/it/', $thisUrl);
        } else {
            $newUrl  = str_replace('/it/', '/en/', $thisUrl);
       }

View::share('newUrl', $newUrl);

When I change first from /it/ to /en/ there are no problems. But when I try to change it from actual /en/ to /it/ it will redirect back to same page but with no locale changed. I've tested with dd the $newUrl variable and the print is correct and the locale is changed every time I change it. But it is not working on <a> tag.

This is how my blade looks like:

<div class="dropdown-menu" aria-labelledby="languageDropdown">
          @if ( Config::get('app.locale') == 'it')
          <a class="dropdown-item" href="{{ $newUrl }}">
            <span class="lang lang-en">English</span>
          </a>
          @elseif ( Config::get('app.locale') == 'en' )
          <a class="dropdown-item" href="{{ $newUrl }}">
            <span class="lang lang-it">Italian</span>
          </a>
          @endif
</div>

Maybe I'm doing something wrong in blade but my mind is really blocked now.

Magalliu's avatar

@khaledw62 and I have to specify that if I use the blade solution will work just fine. If I use AppServiceProvider solution will give me this problem so the locale will be changed only from it to en but not the other way around.

khaledw62's avatar

You May use a foreach instead of if

        //Lets Say You Have Array of Languages
        $langs = ['en' => ['label' => 'English','url' => '']];

        //Remove the current Language Url
        unset($langs[$appLocale]);
        //Generating Urls For All of Your Languages
        foreach ($langs as $lang => $labels) {
            $langs[$lang]['url'] = str_replace('/' . $appLocale . '/', '/' . $lang . '/', $thisUrl);
        }

and in your view

@foreach($langs as $code => $labels)
    <a class="dropdown-item" href="{{ $labels['url'] }}">
        <span class="lang lang-{{ $code }}">{{ $labels['label'] }}</span>
    </a>
    @endforeach

It will work for all array $langs elements but for it' language will not work.

        $thisUrl = url()->current().'/';
        $appLocale = app()->getLocale();


        //Lets Say You Have Array of Languages
        $langs = [
            'en' => ['label' => 'English','url' => ''],
            'it' => ['label' => 'Italian','url' => ''],
            'de' => ['label' => 'German','url' => '']
        ];

        //Remove the current Language Url
        unset($langs[$appLocale]);
        //Generating Urls For All of Your Languages
        foreach ($langs as $lang => $labels) {
            $langs[$lang]['url'] = str_replace('/' . $appLocale . '/', '/' . $lang . '/', $thisUrl);
        }

        View::share('langs', $langs);

Blade:

         @foreach($langs as $code => $labels)
          <a class="dropdown-item" href="{{ $labels['url'] }}">
              <span class="lang lang-{{ $code }}">{{ $labels['label'] }}</span>
          </a>
          @endforeach

It will show en and de but not it. Strange...

I want to specify that my default and fallback_locale are it.
