WEB SCRIPTING (PHP)

Customize the shopping cart program to add at least fifteen different products (think about any real life application shopping cart electronics items, books, consumables etc..). Make sure you apply taxes to your items. You could also try to add a column of quantity next to the item. Write the changes that you have made under your program purpose.

class Product { private $productId; private $productName; private $price;

public function __construct( $productId, $productName, $price ) { $this->productId = $productId; $this->productName = $productName; $this->price = $price; }

public function getId() { return $this->productId; }

public function getName() { return $this->productName; }

public function getPrice() { return $this->price; }

}

$products = array( 1 => new Product( 1, "SuperWidget", 19.99 ), 2 => new Product( 2, "MegaWidget", 29.99 ), 3 => new Product( 3, "WonderWidget", 39.99 ) );

if ( !isset( $_SESSION["cart"] ) ) $_SESSION["cart"] = array();

if ( isset( $_GET["action"] ) and $_GET["action"] == "addItem" ) { addItem(); } elseif ( isset( $_GET["action"] ) and $_GET["action"] == "removeItem" ) { removeItem(); } else { displayCart(); }

function addItem() { global $products; if ( isset( $_GET["productId"] ) and $_GET["productId"] >= 1 and $_GET["productId"]

if ( !isset( $_SESSION["cart"][$productId] ) ) { $_SESSION["cart"][$productId] = $products[$productId]; } }

session_write_close(); header( "Location: shopping_cart.php" ); }

function removeItem() { global $products; if ( isset( $_GET["productId"] ) and $_GET["productId"] >= 1 and $_GET["productId"]

if ( isset( $_SESSION["cart"][$productId] ) ) { unset( $_SESSION["cart"][$productId] ); } }
