Adding more than on Item to cart at time??

[danjapro]

 

I have am working on a shopping cart, for coupong buying.

Here it only allows me to add one Item or One deal ata time into shopping cart.

How can I change this  code to accept more than one deal at a time before checking out.

	{
		// add to cart
		/*
		 $cart = unserialize(JFactory::getSession()->get('cart'));
		 if (empty($cart))
			$cart = new Cart();
			*/
		// We only allow 1 item per cart from now one...
		$cart = new Cart();
		$cart->addItem($deal);
		JFactory::getSession()->set('cart', serialize($cart));

		$dealName = $deal->name;
		$buy4friend = $_GET['buy4friend'];
		$cartItemCount = $cart->getItem($dealId)->getCount();

		if($buy4friend == 1) {
			$msg = $dealName . " :::<b> ". JText::_("DEAL_ADD_TO_CART_MESUN");
			$link = JRoute::_("index.php?option=com_enmasse&controller=shopping&task=viewCart&buy4friend=1", false);
			JFactory::getApplication()->redirect($link, $msg);
		}else{
			$msg = $dealName . " ". JText::_( "DEAL_ADD_TO_CART");
			$link = JRoute::_("index.php?option=com_enmasse&controller=shopping&task=viewCart&buy4friend=0", false);
			JFactory::getApplication()->redirect($link, $msg);
		}
