Call to a member function isEmpty() on a non-object?

I make my view in the controller via:

$data = Lib::index();
    $view = View::make('index')
        ->with('data', $data)
        ->render();
    return $view;

I can check if data is empty in the controller via:

$data->isEmpty();

But when I try the same thing in the view I get the error:

Call to a member function isEmpty() on a non-object

Why?

Here's the code for Lib::index():

   $page = isset($_GET['page']) ? ($_GET['page']) : 1;

    Paginator::setCurrentPage($page);

    try {
        $data = Asset::with(array('sizes'=> function($query){
            $query->select('width', 'height', 'asset_id');
        }))->where('active', 1)->orderBy('updated_at', 'DESC')->paginate(Config::get('p.results_per_page'), array('id', 'alt'));
    }

    catch (QueryException $e) {

        App::abort(404);
    }


    return $data;

consider you are getting some information as collection;

$UserInfo = User::where('phone', $phone_number)->first();

use this code to for error check 

if(empty($UserInfo)){
                return redirect()->back()->withErrors('we don't have a user with this phone number ');
            }

and add below code into your blade 

@if(count($errors)>0)

    <div class="alert alert-danger">
        <ul>

            @foreach($errors->all() as $error)

                <li>{{$error}}</li>

            @endforeach
        </ul>
    </div>
@endif

best regards

isEmpty() is a Collection method. For some weird reasons, in views, it sometimes refer to an empty Collection as null. The safest check, in my opinion would be to do a counts check, like so:

if (count($data)) {...}

This works well both in Controllers and Views.

Try 

> var_dump($data);

in the view.

See what it shows up. This might help further investigate the error.

Then In accordance go ahead with 

>  foreach($data as $moredata){ 
>      $moredata->isEmpty();  }

Should work.
