A reusable shopping cart implementation.

### Install

[](#install)

```
composer require mrprompt/shopping-cart
```

### Using

[](#using)

#### Initializing a cart with items

[](#initializing-a-cart-with-items)

You can initializes a cart passing an array of items. An item is a instance of `Item` class or an implementation of `ItemInterface`.

```
use \MrPrompt\ShoppingCart\Cart;
use \MrPrompt\ShoppingCart\Item;

$items = [
    new Item(uniqid()),
    new Item(uniqid(), 1.00),
    new Item(uniqid(), 5.00, 10),
];

$cartId = uniqid();

$cart = new Cart($cartId, $items);
```

#### Add items to cart

[](#add-items-to-cart)

You can add items to an existent cart passing an instance of `Item`.

```
use \MrPrompt\ShoppingCart\Item;

$itemId = uniqid();
$itemPrice = 1.99;
$itemQuantity = 30;

$item = new Item($itemId, $itemPrice, $itemQuantity);

$cartId = uniqid();

$cart = new Cart($cartId);
$cart->addItem($item);
```

#### Remove an item from cart

[](#remove-an-item-from-cart)

Pass an instance of `Item` - previously added to cart obvously - to remove it.

```
use \MrPrompt\ShoppingCart\Item;

$itemId = uniqid();
$itemPrice = 1.99;
$itemQuantity = 30;

$item = new Item($itemId, $itemPrice, $itemQuantity);

$cartId = uniqid();
$cart = new Cart([ $item ]);
$cart->removeItem($item);
```

#### Cleanup the cart

[](#cleanup-the-cart)

To remove all items from cart, you can use the `cleanUp` method:

```
use \MrPrompt\ShoppingCart\Cart;
use \MrPrompt\ShoppingCart\Item;

$itemId = uniqid();
$itemPrice = 1.99;
$itemQuantity = 30;
$item = new Item($itemId, $itemPrice, $itemQuantity);

$cartId = uniqid();
$cart = new Cart($cartId, [ $item ]);
echo $cart->count(); // === 1

$cart->cleanUp();

echo $cart->count(); // === 0
```

#### Check if cart is empty

[](#check-if-cart-is-empty)

To check if the cart is empty, you can use `isEmpty` method:

```
use \MrPrompt\ShoppingCart\Cart;
use \MrPrompt\ShoppingCart\Item;

$itemId = uniqid();
$itemPrice = 1.99;
$itemQuantity = 30;
$item = new Item($itemId, $itemPrice, $itemQuantity);

$cartId = uniqid();

$cart = new Cart($cartId, [ $item ]);
echo $cart->isEmpty(); // === false

$cart->cleanUp();

echo $cart->isEmpty(); // === true
```
