Laravel pagination redirects to home route after clicked on link for page 2

Question

My Laravel pagination is not working properly. When I try to click on second link in laravel pagination or another one instead of first, it redirects me to home url (localhost:8000).

Laravel pagination links are redirecting to same route but with "page=" parameter but the problem is that on this route I have controller with if statements which redirects me to home page. How can I send my pagination results to another route and display every pagination page properly without get affected by controllers.

Here is controller:

    $per_page = 5; //default

    //Za ispis kategorija i tagova u filteru
    $filter_categories = Category::all();
    $filter_tags = Tag::all();


    if($request->per_page){ $per_page = $request->per_page; }


    //Ako ne postoji zahtjev za kategorijama i tagovima
    if(!$request->category && !$request->tags) {

        //Provjera da li postoji zahtjev za broj jela po stranici
        if(only_meals_per_page($request)){

            $meals = Meal::paginate($per_page);

            return view('index', compact('meals', 'filter_categories', 'filter_tags'));
        }

        //Ako ne postoji nikakvi zahtjev vrati se na početak
        return redirect('/');

    //Zahtjev za kategorijom
    } else if($request->category && !$request->tags) {

        $result = filter_meals_by_category($request->category, $per_page);

    //Zahtjev za tagovima
    } else if(!$request->category && $request->tags) {

        $result = filter_meals_by_tags($request->tags, $per_page);

    //Zahtjev za kategorijama i tagovima
    } else {

        $result = filter_meals_by_categories_and_tags($request->category, $request->tags, $per_page);

    }

    $meals = $result['meals'];
    $message = $result['message'];

    Session::flash('message', $message);
    return view('index', compact('meals', 'filter_categories', 'filter_tags'));

..and example of $result array with pagination metod

$meals = Meal::where('category_id','=', NULL)->paginate($per_page);

I know that the problem is probably in first if statement which redirects me to home because there were no categories and tags in request anymore.

Problem fixed with appending query string of get request in pagination links:

$meals->appends(request()->input())->links()
