Usage

Regiser facade in config/app.php

'Cart' => 'Melihovv\ShoppingCart\Facades\ShoppingCart',

or

use Melihovv\ShoppingCart\Facades\ShoppingCart as Cart;

in the below examples.

The shopping cart gives you the following methods to use:

Cart::add()

Add an item to the shopping cart.

$cartItem = Cart::add($id, $name, $price, $quantity);
$cartItem = Cart::add($id, $name, $price, $quantity, [
    'color' => 'white',
]);

Cart::remove()

Remove the item with the specified unique id from the shopping cart. Unique id is used to store items with the same $id, but different $options.

$cartItem = Cart::add($id, $name, $price, $quantity);

// ...

Cart::remove($cartItem->getUniqueId())

Cart::has()

Check if the shopping cart contains the item with the specified unique id.

$cartItem = Cart::add($id, $name, $price, $quantity);

// ...

if (Cart::has($cartItem->getUniqueId())) {
    // Do smth.
}

Cart::get()

Get an item in the shopping cart by its unique id.

$cartItem = Cart::add($id, $name, $price, $quantity);

// ...

$cartItem = Cart::get($cartItem->getUniqueId());

Cart::content()

Get all items in the shopping cart.

Cart::clear()

Clear the shopping cart.

Cart::count()

Return number of items in the shopping cart. This method does not summarize quantities of item. For example, there are 3 books and 1 iPhone in the shopping cart, so this method returns 2.

Cart::getTotal()

Return total price of all items in the shopping cart.

Cart::add(1, 'iPhone 7', 500, 1);
Cart::add(1, 'iPad Pro', 700, 2);
Cart::getTotal(); // return 1900

Instances

The package supports multiple instances of the cart. Some examples:

Cart::instance('shopping')->add('192ao12', 'Product 1', 100, 10);

// Store and get the content of the 'shopping' cart
Cart::store->content();

Cart::instance('wishlist')->add('sdjk922', 'Product 2', 50, 1, ['size' => 'medium']);

// Store and get the content of the 'wishlist' cart
Cart::store()->content();

// If you want to get the content of the 'shopping' cart again
Cart::instance('shopping')->restore()->content();

The default cart instance is called default, so when you're not using instances,Cart::content(); is the same as Cart::instance('default')->content().

Cart::instance()

Set current instance name.

Cart::currentInstance()

Get current instance name.

Storage

Currently there are two possible storage to persist shopping cart:

• Database
• Redis

You can choose one by specifying repository class name in config

// config/shopping-cart.php

'repository' => \Melihovv\ShoppingCart\Repositories\ShoppingCartDatabaseRepository::class,
// or
'repository' => \Melihovv\ShoppingCart\Repositories\ShoppingCartRedisRepository::class,

In order to use redis storage you also need to install predis/predis package.

Cart::store()

Persist current shopping cart instance to storage.

Cart::store($user->id);
Cart::instance('cart')->store($user->id);
Cart::instance('wishlist')->store($user->id);

Cart::restore()

Restore shopping cart instance to storage.

Cart::restore($user->id);
Cart::instance('cart')->restore($user->id);
Cart::instance('wishlist')->restore($user->id);

Cart::destroy()

Remove shopping cart instance from storage.

Cart::destroy($user->id);
Cart::instance('cart')->destroy($user->id);
Cart::instance('wishlist')->destroy($user->id);

Coupons

You can easily add discount coupons to shopping cart. Currently there are two types of coupons:

• FixedDiscountCoupon
• PercentDiscountCoupon

Related methods:

Cart::addCoupon()

Add coupon to cart.

Cart::addCoupon(new FixedDiscountCoupon($name, $discount));
Cart::addCoupon(new PercentDiscountCoupon($name, 0.1)); // 10% discount

Cart::coupons()

Returns all coupons.

Cart::getTotalWithCoupons()

Returns total price with applied coupons.

Cart::add(1, 'iPhone 7', 500, 1);
Cart::add(1, 'iPad Pro', 700, 2);
Cart::addCoupon(new FixedDiscountCoupon($name, 300));
Cart::getTotal(); // return 1900 - 300 = 1600
