I'm working with magento2, I have created custom add to cart product functionality. Now I want update product quantity. I have fetched all cart items and I want update but I am getting incorrect quantities of configurable child product. I have fetched quantity using $item->getQty() inside cart get all items it is working fine with normal product. But I get incorrect cart item quantity for child configurable product. Can we use any other way instead of $item->getQty() I have also configurable child product I'ds.

To get the children quantity you need to check if the item in the cart has children first then go through children, this code will show you how you can get the QTY of the children
if ($item->getHasChildren() ) {
foreach ($item->getChildren() as $child) {
// get child quantity by this calling $child->getQty();
}
}
where $item is the the cart item
this code works well for me, I hope it will help you.

Thanks for quick reply @wisam hakim suppose I have three child then there is no need to other conditions or check for perticular child product from your given code. Apr 18, 2018 at 4:00

usually in configurable product you will have only one child, the condition is needed in case you have two products in the cart, one is simple product and other is configurable, in this case you need the condition to not have any error in your code Apr 18, 2018 at 4:06

if you have the item object then you can directly fetch the child product from the items as follows; If you check for each quote item we have the record in the "quote_item_option" table and the details can be fetch using method "getOptionByCode('simple_product')"
foreach ($cart->getQuote()->getAllVisibleItems() as $item) {
$productId = $item->getProduct()->getId(); // parent product id
$childItemId = $item->getOptionByCode('simple_product')->getProduct()->getId(); // child product id
}
A very late answer but hope it helps others.
