Updating Cart Item Quantity ​

You can easily update the quantity of an item in the cart using either Cart::updateQuantity() or cart()->updateQuantity() method. This is useful when a customer wants to change the quantity of an item before checkout.

Method Signature ​

php
Cart::updateQuantity(mixed $id, int $quantity);
Cart::updateQuantity(mixed $id, int $quantity);

or

php
cart()->updateQuantity(mixed $id, int $quantity);
cart()->updateQuantity(mixed $id, int $quantity);

Parameters ​

  • $id (mixed): The unique identifier of the item you want to update.
  • $quantity (int): The new quantity you want to set for the item.

Using cart()->updateQuantity():
