Publish configuration file

Requirements

• PHP 8.5+
• Laravel 13.0

Basic Usage

Adding an item to the shopping cart.

Note: Cart item constructor properties are validated when creating or updating cart items.

Note: A unique random integer rowId is created and used to identify cart items.

use TomShaw\ShopCart\{Cart, CartItem};

$cartItem = CartItem::make(id: $product->id, name: $product->name, quantity: 1, price: $product->price);

Cart::add($cartItem);

Adding an item with product options to the shopping cart.

$cartItem = CartItem::make($product->id, $product->name, 1, $product->price);

$cartItem->options['size'] = 'XL';
$cartItem->options['logo'] = 'Laravel Rocks';

Cart::add($cartItem);

Accessing product options.

// Array access
$size = $cartItem->options['size'];

// Or using Collection methods
$size = $cartItem->options->get('size');
$cartItem->options->put('color', 'blue');
$hasSize = $cartItem->options->has('size');

Updating an item and product options in the shopping cart.

$cartItem = Cart::all()->where('id', '===', $id)->first();

$cartItem->quantity = 5;
$cartItem->options['size'] = '2XL';

Cart::update($cartItem);

Removing an item from the shopping cart.

Cart::remove(Cart::get($rowId));

Deleting the shopping cart after checkout.

Cart::forget();

Cart Totals

Sums the properties: tax, price, subtotal and quantity.

$totalPrice = Cart::total('price');

$totalQuantity = Cart::total(property: 'quantity', numberFormat: false);

$subTotal = Cart::total('subtotal');

$totalTax = Cart::total('tax');

Computed Properties

Cart items automatically calculate subTotal, totalTax, and totalPrice. These values are computed on-demand and are always accurate.

$cartItem = CartItem::make(id: 1, name: 'Product', quantity: 2, price: 100.00, tax: 8.5);

// Automatically computed properties
echo $cartItem->subTotal;    // 200.00 (quantity * price)
echo $cartItem->totalTax;    // 17.00 (subTotal * tax / 100)
echo $cartItem->totalPrice;  // 217.00 (subTotal + totalTax)

// Values update automatically when properties change
$cartItem->quantity = 3;
echo $cartItem->subTotal;    // 300.00 (automatically recalculated)

Tax Rates

To set a default tax rate add the following environment variable in your application .env.

SHOPCART_DEFAULT_TAXRATE=9.547

You can easily apply item specific tax rates at run time.

use TomShaw\ShopCart\{Cart, CartItem};

Cart::add(CartItem::make(tax: 6.250, ...));

Number Formatting

Number formating is handled by adding the following environment variables to your application .env.

SHOPCART_DECIMALS=2
SHOPCART_DECIMAL_SEPARATOR="."
SHOPCART_THOUSANDS_SEPARATOR=","

Cart Methods

Get item from collection by rowId.

$cartItem = Cart::get($rowId);

Check if cart item exists by rowId.

$boolean = Cart::has($rowId);

Get cart as collection or array.

$cartItems = Cart::all(bool $toArray = false);

Use Laravel Collection methods for advanced operations.

// Search for specific cart items
$cartItems = Cart::all()->where('id', '===', $productId);

// Check if cart is empty
$isEmpty = Cart::all()->isEmpty();
$isNotEmpty = Cart::all()->isNotEmpty();

// Filter, map, or use any Collection method
$total = Cart::all()->sum('totalPrice');
$firstItem = Cart::all()->first();

Casting the cart as an array or json;

Cart::toArray();

Cart::toJson();
