I am trying to search by check-boxes and conditions but i get this error in return:

count(): Parameter must be an array or an object that implements Countable

Logic

1. I can select 1 or more options


2. In back-end check what kind of options has selected


3. Depend of the kind return results

Code

controller

public function advancedsearch(Request $request) {

    $options = Specification::whereHas('subspecifications')->with(['subspecifications' => function($query) {

        $query->status('Active');

    }])->get();

    $brands = Brand::all();

    $brandss = Input::has('brands') ? Input::get('brands') : ;

    $suboption = Input::has('suboptions') ? (int)Input::get('suboptions') : ;

    $min_price = Input::has('min_price') ? (int)Input::get('min_price') : null;

    $max_price = Input::has('max_price') ? (int)Input::get('max_price') : null;



    //codes

    if(count($request['suboptions'])){

      $products = DB::table('products')

      ->join('product_subspecification', function ($join) {

        $suboption = Input::has('suboptions') ? Input::get('suboptions') : ;

            $join->on('products.id', '=', 'product_subspecification.product_id')

                 ->where('product_subspecification.subspecification_id', '=', $suboption);

        })

      ->paginate(12);

    }



    elseif(count($request['brands'])){

      $products = DB::table('products')

      ->whereIn('products.brand_id', $brandss)

      ->paginate(12);

    }



    elseif(count($request['min_price']) && count($request['max_price'])){

      $products = DB::table('products')

      ->whereBetween('price', [$min_price, $max_price])

      ->paginate(12);

    }





    return view('front.advancesearch', compact('products', 'brands', 'options'));

    }

Summary of code above

I am getting all brands from database and check if only 1 brand has selected or several

$brands = Brand::all();

$brandss = Input::has('brands') ? Input::get('brands') : ;

Then I check if any brand has selected in general or no by count and returning results

elseif(count($request['brands'])){

      $products = DB::table('products')

      ->whereIn('products.brand_id', $brandss)

      ->paginate(12);

}

but I get error I share above.

Any idea?

Update

how my html look likes

how the result **dd** look like

array:4 [▼

  "_token" => "Wqs9yzd5qwGtbv01asbCzsISeVQxHsCoWVQM1ifO"

  "brands" => array:1 [▼

    0 => "3"

  ]

  "min_price" => null

  "max_price" => null

]

Blade

<div class="checkbox">

    @foreach($option->subspecifications as $suboption)



        @if($option->title == 'Brand')

            <label for="brands">

            <input name="brands" type="checkbox" value="{{$suboption->id}}">

            {{ucfirst($suboption->title)}}

            </label>

        @else

            <label for="suboptions">

            <input name="suboptions" type="checkbox" value="{{$suboption->id}}">

            {{ucfirst($suboption->title)}}

            </label>

        @endif



    @endforeach

</div>

Solved

Changed count with has solved the issue

elseif($request->has['brands']){

PS: Based on 3 different functions that I have, which returns data of my search I have mixed results but it doesn't related to this
question. count error solved so I'll mark it as solved.
