Machen Sie Einkaufswagen in Laravel

dort ich möchte Warenkorb in meinem Projekt hinzufügen. Ich habe versucht, es zu machen, aber es will immer noch arbeiten.Machen Sie Einkaufswagen in Laravel

dies mein Controller:

function postCreate(){ 

     echo '<pre>'; 
     print_r(Request::all()); 
     exit; 
     $data['list'] = DB::table('package') 
     ->join("cms_car","cms_car.id","=","package.id_cms_car") 
     ->join("zone","zone.id","=","package.id_zone") 
     ->select("package.*","cms_car.car as name_car","cms_car.photo as car_photo");  


     return view('detail',$data); 
    }

und hier meiner Meinung nach für die Liste:

@if ($row->driver == 'Driver Included') 
      <img src="{{ asset('assets/assets/icon/ic-petrol.png') }}" style="max-width:15px;"> 
     @else 

     @endif 

     {{$row->driver}}</p> 
     <p> 
     @if ($row->driver == 'Driver Included') 
      <img src="{{ asset('assets/assets/icon/ic-driver.png') }}"style="max-width:15px;"> 
     @else 

     @endif 
     {{$row->fuel}}</p> 
     <h6 class="post-price">price :</h6> 
     <p>Rp. {{$row->price}}</p> 
    </div> 
</div> 
<hr> 
<div class="col-md-6"> 
Unit Quality :<br><br> 
    <div class="input-group" style="width: 150px;"> 
<span class="input-group-btn"> 
       <button type="button" class="btn btn-danger btn-number btn-minus" data-type="minus"> 
       <span class="glyphicon glyphicon-minus"></span> 
       </button> 
      </span> 
      <input type="text" name="quantity" class="form-control input-number" value="1" data-price="{{$row->price}}" data-id="{{$row->id}}" min="1" max="100"> 
      <span class="input-group-btn"> 
       <button type="button" class="btn btn-success btn-number btn-plus" data-type="plus"> 
        <span class="glyphicon glyphicon-plus"></span> 
       </button> 
      </span> 
</div> 
</div> 

<div class="col-md-6"> 

    <h3 style="margin-top:40px" id="price{{$row->id}}">Rp. {{number_format($row->price)}}</h3> 
</div> 
    </div> 
    </div> 
    @endforeach
