Laravel - Drop down list where statement - laravel

Question

I currently have a single drop down list that when i select the value it will display the data. However i am now adding in a new drop down list but when i press submit nothing is appearing.
I select distance and press submit data is presented. However, I have now included a price drop down list however nothing is appearing when i press submit. Can someone please help, see code:
SearchController.php
public function index(Request $request)
{
$distances = DB::table('posts')->select('distance')->distinct()->get()->pluck('distance');
$prices = DB::table('posts')->select('price')->distinct()->get()->pluck('price');
$postsInRange = $request->has('distance')
? Post::where('distance', $request->distance)->get()
: [];
return view('Pages.search', [
'distances' => $distances,
'prices' => $prices,
'posts' => $postsInRange
]);
Search.php
<div class="form-group">
<select name="distance" id="distance" class="form-control input-lg dynamic"
data-dependent="state">
<option value="">Distance</option>
#foreach($distances as $distance)
<option value="{{ $distance }}">{{ $distance }}</option>
#endforeach
</select>
<br>
<select name="price" id="price" class="form-control input-lg dynamic" data-
dependent="state">
<option value="">Price</option>
#foreach($prices as $price)
<option value="{{ $price}}">{{ $price}}</option>
#endforeach
</select>

Try this:
public function index(Request $request)
{
$distances = DB::table('posts')->select('distance')->distinct()->get()->pluck('distance');
$prices = DB::table('posts')->select('price')->distinct()->get()->pluck('price');
$postsInRange = $request->has('distance') ? Post::where('distance', $request->distance)->get()
: [];
$postsPrice = $request->has('price') ? Post::where('price', $request->price)->get()
: [];
return view('Pages.search', [
'distances' => $distances,
'prices' => $prices,
'posts' => $postsInRange,
'postsPrice' => $postsPrice
]);
