I am getting some strange problem... as title said...

I am making post request to change lang value by setting lang forever cookie.

After that I am checking if cookie exist and if it does to app()->setLocale(\Cookie::get('lang')) and then use {{ app()->getLocale() }} which returns stored lang value as en or fr.

But still page is loading config/app.php => 'locale'=>'en'...

Can I at least change config('app.locale') value to \Cookie::get('lang') or do you know what can be a problem here?

Thanks

UPDATE:

I found the answer, I need to add to every file inside views folder - new locale value to be able to retrieve right lang content.. I don't know why because I never had problem before but if somebody else have problem this may be solution.

The app()->setLocale('fr') will change the locale for the duration of the request to 'fr'. So if after setting it, you call app()->getLocale(), it will return 'fr'.

If your application reads locale from config('app.locale') in some places, you can change the value on the go like this:

config(['app.locale' => 'fr'])

Then the config('app.locale') will return 'fr' for the duration of the request

  • I found that and I did it but I found also that setLocale is being set in my master.blade which is as template for every page, but on other sections like if I call getLocale from other sections from other files like home.blade which extends master locale is back to en.... –  Jun 17 '18 at 03:02
  • Thats for both config.app.locale and fot app()->setLocale() they are only set in master file but others which are extending master file are back to default one... –  Jun 17 '18 at 03:06
  • I found answer, but I never had problem with this like this.... It seems that for each file in views I need to setLocale to cookie value.... –  Jun 17 '18 at 03:14
  • I recommend setting the locale with middleware, then all views should be affected – DevK Jun 17 '18 at 03:31
  • Can you post me an example, it's true I haven't sleep whole night and my brain is off but I would like to accept your answer as well :D –  Jun 17 '18 at 03:38

Probably you change the locale not in the right place. You should use app/Providers/AppServiceProvider.php to do that.

Innside boot method you could add something like this:

$this->app->setLocale(\Cookie::get('lang', 'en')

And then you will have language set all the time - when cookie is set to the value from cookie, otherwise to en

Then in your view you don't need to do anything. You can just use:

{{ trans('some.translated') }}

and it will be translated into valid language when you set translation in translation files.

  • Whats is the difference between __('something') and trans('something') ? –  Jun 18 '18 at 12:29
  • @StupidKid `__` first reads from Json translations and then from array format, and `trans` only loads array translations – Marcin Nabiałek Jun 18 '18 at 13:05
  • Okay enough to accept the answer, btw I totally forgot for boot method.. Can I pass through boot some model used on every page and view on the app? –  Jun 18 '18 at 13:15
  • For this you should rather use https://laravel.com/docs/5.6/views#view-composers or take a look at https://laravel.com/docs/5.6/views#passing-data-to-views – Marcin Nabiałek Jun 18 '18 at 13:17
