Updating Cart Item Price ​

You can update the price of an item in the cart using either Cart::updatePrice() or cart()->updatePrice() method. This can be useful if the price of an item changes or if you want to apply a discount.

Method Signature ​

php
Cart::updatePrice(mixed $id, float $price);
Cart::updatePrice(mixed $id, float $price);

or

php
cart()->updatePrice(mixed $id, float $price);
cart()->updatePrice(mixed $id, float $price);

Parameters ​

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

Example ​

Using Cart::updatePrice():

php
use RealRashid\Cart\Facades\Cart;

// Update the price of an item
Cart::updatePrice(3, 30.00);
use RealRashid\Cart\Facades\Cart;

// Update the price of an item
Cart::updatePrice(3, 30.00);

Using cart()->updatePrice():

php
// Update the price of an item
cart()->updatePrice(3, 30.00);
// Update the price of an item
cart()->updatePrice(3, 30.00);

In both examples, we're updating the price of the item with ID 3 to 30.00.
