$data['popular_rooms'] = Rooms::where('status','Listed')->get();
$data['property_rooms'] = PropertyRooms::select("property_room.*","rooms_photos.name", "rooms_price.night")
->join("rooms_photos","rooms_photos.room_id","=","property_room.room_id")

//home page two data start
$data['reservation'] = Reservation::orderBy('id', 'desc')->where('status','Accepted')->groupBy('room_id')->limit(10)->get();
$data['view_count'] = Rooms::orderBy('views_count', 'desc')->where('status','Listed')->groupBy('id')->get();
$data['recommented'] = Rooms::orderBy('id', 'desc')->where('recommended','Yes')->where('status','Listed')->groupBy('id')->get();
$data['res_count'] = count($data['reservation']);
$data['room_view_count'] = count($data['view_count']);
$data['room_recommented_view'] = count($data['recommented']) ;
//redirect home page
if($data['redirect'][0]->value == 'home_two')
{
$data['default_home'] = 'two' ;return view('home.home_two',$data);
}
else
{
return view('home.home', $data);
}
}
route:
Route::group(['middleware' => ['install','locale']], function () {
Route::get('/', 'HomeController#index');
});
In this code I have to run my index file inside the controller but when I server php artisan it throw an offset error i.e. ErrorException in Collection.php line 1043: Undefined offset: 0. I don't know why where I am doing wrong? Please help me.
Thank You

You need to check that the index is present before accessing it.
isset($data['redirect'][0])
if(isset($data['redirect'][0])) {
if($data['redirect'][0]->value == 'home_two') {
$data['default_home'] = 'two';
return view('home.home_two',$data);
}
}
