如何在laravel的darryldecode购物车中设置最大数量？

Question

            \Cart::add(array(
                'id' => $request->test,
                'name' => $price->tests->item_name,
                'quantity' => 1,
                'price' => $price->price,
                'attributes' => array(
                    'lab_logo' => $price->labs->logo,
                    'lab_name' => $price->labs->name,
                    'item_number' => $price->tests->item_number
                ),
            ));

When i add the same product it increments the item quantity but i want the quantity of the item to be 1 at max.

According to the documentation :

// NOTE: as you can see by default, the quantity update is relative to its current value
// if you want to just totally replace the quantity instead of incrementing or decrementing its current quantity value
// you can pass an array in quantity value like so:
Cart::update(456, array(
  'quantity' => array(
      'relative' => false,
      'value' => 5
  ),
));

So, if you pass an array on add and override it to not be relative , it should work as expected:

Cart::add(array(
   'id' => $request->test,
   'name' => $price->tests->item_name,
   'quantity' => array(
      'relative' => false,
      'value' => 1,
   ),
   'price' => $price->price,
   'attributes' => array(
      'lab_logo' => $price->labs->logo,
      'lab_name' => $price->labs->name,
      'item_number' => $price->tests->item_number
   ),
));
