LaravelShoppingcart is a PHP package that adds shopping cart functionality to web applications built with Laravel, a popular PHP web framework. It handles the common tasks any online store needs: adding products to a cart, updating quantities, removing items, calculating totals with tax, and wiping the cart clean when a purchase is complete. Adding items to the cart is straightforward. You pass in a product ID, name, quantity, and price. You can also attach extra options, like a size or color, so the same product can appear multiple times in the cart with different configurations. The package also supports a concept called a Buyable interface that lets your database model plug directly into the cart without manually specifying each field every time. The cart tracks each line item by a unique row ID. You use that ID to update quantities, swap in new product details, or remove the item entirely. To see everything currently in the cart, a content method returns a list of items you can display to the customer. Several built-in methods handle the math. A total method gives the grand total, a tax method returns the tax portion, and a subtotal method returns the total before tax. All three can be formatted with custom decimal and thousand separators. Tax rates are configurable via a config file. For more advanced use cases, the package supports multiple separate cart instances on one page (for example, a main cart and a wishlist), optional database storage so carts survive between sessions, and events that fire when items are added or removed. The README gives code examples for each of these features.
