Easy PHP Cart

This class allows you to add and remove products from an OOP cart. Cart is managed in the session so it is saved between pages and optionally between visits (depending on session configuration).

Usage example

// Start sessions
session_start();
// Set all errors to ON for development and to 0 (zero) when public
error_reporting(E_ALL);

// require the class
require 'class.cart.inc.php';

// set cart name [session key]
$cartName = 'basicCart';

// instance the cart class
$cart = new cart($cartName);

// Add some products to the cart. 
// Here we add a product with an ID of 23, and a quantity of 8.
$cart->addProduct(23, 8, false);
// Set special discount for this product
$cart->discount = 32;

// The 3rd argument allows you to increase quantity if the product exists
$cart->addProduct(16, 2, true);

// set special discount for this too
$cart->addProduct(53, 5, false);
$cart->discount = 35;
$cart->bonusProduct = 11;

echo 'We have '.$cart->cartCount().' products';
$cart->viewCart();
