Laravel – display data from using data ranges

I want to display data based on ranges within a drop down menu list.I currently have singular values where i would select the value 10 and it would display all values that = 10.

Now i want to have a drop down menu with the options of 5-10, 11-15, 16-20 and i expect it to display all data within those ranges. See code below

Search.php

<select name="distance" id="distance" class="form-control input-lg dynamic" data-dependent="state">
    <option value="">Choose an item</option>
    @foreach($distances as $distance)
        <option value="{{ $distance }}">{{ $distance }}</option>
    @endforeach
</select>

Search.Controller.php

public function index(Request $request)
{
    $distances = DB::table('posts')->select('distance')->distinct()->get()->pluck('distance');

    $postsInRange = $request->has('distance')
        ? Post::where('distance', $request->distance)->get()
        : [];

    return view('Pages.search', [
        'distances' => $distances,
        'posts' => $postsInRange
    ]);
}

public function store(Request $request)
{
    // This will return all request data to your screen.
    return $request->all();
    return view('Pages.search');
}

How would i manage to display the the data using data ranges instead of singular values.

Answer

You can use collection’s groupBy function:

$distancesByGroup = DB::table('posts')
    ->distinct()
    ->pluck('distance')
    ->groupBy(function ($item, $key) {
        return (int) ((int) $item / 5);
    });

And on your blade:

@foreach($distancesByGroup as $group => $distances)

    <optgroup label="{{ $group * 5 }} - {{ ($group + 1) * 5 }}">

    @foreach($distances as $distance)
        <option value="{{ $distance }}">{{ $distance }}</option>
    @endforeach

@endforeach

Note: I haven’t tested it but it gives you the idea.
