Usage

The ShoppingCart gives you the following methods to use:

Cart::add()

Adding an item to the cart is really simple, you just use the add() method, which accepts a variety of parameters.

In its most basic form you can specify the product Model, quantity ($qty) you'd like to add to the cart. note that the Product model must have a price column.

Cart::add($productModel, $qty);

if you didnt specify the $qty the cart will assume its 1 item.

As an optional third parameter you can pass it options, so you can add multiple items with the same id, but with (for instance) a different size or color for example.

Cart::add($productModel, $qty, ['size' => 'large', 'color' => 'black']);

The add() method will return CartItem array of the item you just added to the cart.

Cart::modify()

To modify an item in the cart, you'll first need the uinqueIndex of the item.

the uniqueIndex is the item offset in the cart Model items array.

Next you can use the modify() method to modify it.

If you simply want to modify the quantity, you'll pass the modify method the uinqueIndex and the new quantity:

$uinqueIndex = '20185a4530208f76b2ef3eb95307a021';

Cart::modify($uinqueIndex, 2); // Will modify the quantity

Cart::reduceOneItem()

to reduce certain Cart item quantity by 1, you'll first need the uinqueIndex of the item.

then

$uinqueIndex = '20185a4530208f76b2ef3eb95307a021';

Cart::reduceOneItem($uinqueIndex); // will reduce item quantity by 1

Cart::remove()

To remove an item for the cart, you'll again need the uniqueIndex. This uniqueIndex you simply pass to the remove() method and it will remove the item from the cart.

$uniqueIndex = '20185a4530208f76b2ef3eb95307a021';

Cart::remove($uniqueIndex);

Cart::getContent()

Of course you also want to get the carts content. This is where you'll use the getContent method. This method will return a Cart model which you can iterate over and show the content to your customers.

Cart::getContent();

Cart::destroy()

If you want to completely remove the content of a cart, you can call the destroy method on the cart. This will remove the cart from Session.

Cart::destroy();

Cart::total()

The total() method can be used to get the calculated total of all items in the cart, given there price and quantity.

Cart::total();

Cart::count()

If you want to know how many items there are in your cart, you can use the count() method. This method will return the total number of items in the cart. So if you've added 2 books and 1 shirt, it will return 3 items.

Cart::count();

Exceptions

The Cart package will throw exceptions if something goes wrong. This way it's easier to debug your code using the Cart package or to handle the error based on the type of exceptions. The Cart packages can throw the following exceptions:

Exception	Reason
CartIsEmptyException	When trying to modify or reduce a cart item and the cart already empty
InvalidUniqueIndexException	When the uniqueIndex that got passed doesn't exists in the cart
InvalidQuantityException	When you try to add negative or float quantity.

Events

The cart also has events build in. There are five events available for you to listen for.

Event	Fired	Parameter
cartItem.added	When an item was added to the cart.	The CartItem that was added.
cartItem.modified	When an item in the cart was modified or reduced by 1.	The CartItem that was modified.
cartItem.removed	When an item is removed from the cart.	The CartItem that was removed.
cart.destroyed	When the content of a cart was destroyed.	return the removed Cart Model.
