Localization tips

Middleware will be processed before construct, so manipulate session in construct will not work.

    public function __construct(){
        //parent::__construct();

        $this->middleware(function ($request, $next) {
            $locale = $request->input('locale');
            if($locale != false){
                session()->put('locale', $locale);
                App()->setLocale($locale);
            }else if(session()->get('locale') != false){
                App()->setLocale(session()->get('locale'));
            }

            return $next($request);
        });
    }

public function __construct(){

//parent::__construct();

$this->middleware(function ($request, $next) {

$locale = $request->input('locale');

if($locale != false){

session()->put('locale', $locale);

App()->setLocale($locale);

}else if(session()->get('locale') != false){

App()->setLocale(session()->get('locale'));

}

return $next($request);

});

}

Method links does not exist error

When using voyager with(‘translations’) and paginate together, this error occurs when creating pagination links.

Original:

//Controller
$news_list = News::list_data($latest->id, 1);
$data['news_list'] = $news_list->translate(App()->getLocale());

//View
{{ $news_list->links() }}

//Controller

$news_list = News::list_data($latest->id, 1);

$data['news_list'] = $news_list->translate(App()->getLocale());

//View

Solution:

//Controller
$news_list = News::list_data($latest->id, 1);
$data['news_list'] = $news_list;

//View
@foreach($news_list as $news)
    <h2>{!!nl2br($news->getTranslatedAttribute('title', $locale))!!}</h2>
@endforeach

{{ $news_list->links() }}

//Controller

$news_list = News::list_data($latest->id, 1);

$data['news_list'] = $news_list;

//View

@foreach($news_list as $news)

<h2>{!!nl2br($news->getTranslatedAttribute('title', $locale))!!}</h2>

@endforeach

Solution 2:

    public function products(Request $req)
    {
        $data = $this->init_data();

        $products = Product::orderBy('created_at')
            ->paginate(2);
        //dd($page_data);

        foreach ($products as $key => $product) {
            $product->text1 = $product->getTranslatedAttribute('text1', App()->getLocale(), 'zhtw');
        }

        $data['products'] = $products;
        
        return view('products', $data);
    }
