如何在Laravel中使用selects进行搜索？

<form action="/search" method="GET">
    <select name="category">
        <option value="1">Category 1</option>
        <option value="2">Category 2</option>
        <option value="3">Category 3</option>
    </select>
    <button type="submit">Search</button>
</form>

Route::get('/search', 'SearchController@search');

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Product;

class SearchController extends Controller
{
    public function search(Request $request)
    {
        $category = $request->input('category');

        $products = Product::where('category', $category)->get();

        return view('search-results', ['products' => $products]);
    }
}

@foreach ($products as $product)
    <div>{{ $product->name }}</div>
    <div>{{ $product->description }}</div>
@endforeach
