         [ price,description,productname,uniqueid, category, gender,size,  quantity, shippingValue,  date]
        );

I don't know at all but you can do it to use ajax

Example:

Create a route:

Route::post('add-to-cart/{product}', CartController@addToCart);

In cart controller:

public function addToCart($product){
  //if you use data as a string
  $data = $product->split(";")

  \App\Cart::create([
    'product_id' => data[0],
    'quantity' => .....,
    'user_id' => .....,\
    ..........
  ]);
}

Ajax:

$('#addToCart').click(function(){
//you can use javascript to get data from html

var data= "";
data += product_id + ";";
//or some thing you like to store in data
//You can use data as a array

  $.ajax({
     url: "{{ url('add-to-cart') }}" + '/' + data,
     type: 'POST',
     data: {
       "_token" : {{csrf_token()}},
       "data" : data
     },
    success: function(data){
      //Do some code to update cart on html
    }

  });
});
