Visually Highlight/Flag "Always Free Shipping" products in the shopping cart

[lhungil]

... separate out the code (header and template).

Code doing processing in an observer (or header files). Code displaying stuff (HTML / CSS) in the template files.

I do in fact want an indicator next to each "always free shipping" product [in the shopping cart and checkout].. I might mess around and see if I can make myself a combo platter here..

Sounds like fun! I'd probably do something like the following (untested):

Create "/includes/classes/observers/freeShippingObserver.php"

<?php
class freeShippingObserver extends base {

	protected $logfile;

	function __construct() {
		$this->attach($this, array(
			'NOTIFY_HEADER_END_SHOPPING_CART',
			'NOTIFY_HEADER_END_CHECKOUT_SHIPPING',
			'NOTIFY_HEADER_END_CHECKOUT_PAYMENT',
			'NOTIFY_HEADER_END_CHECKOUT_CONFIRMATION'
		));
	}

	function update(&$class, $eventID, $paramsArray = array()) {
		global $cart_includes_free_shipping_product;

		$cart_includes_free_shipping_product = false;
		if(array_key_exists('cart', $_SESSION)) {
			$cart_includes_free_shipping_product = $_SESSION['cart']->in_cart_check('product_is_always_free_shipping','1');

			global $products;
			$n=sizeof($products);
			if($n > 0) {
				switch($eventID) {
					case 'NOTIFY_HEADER_END_SHOPPING_CART':
						global $productArray;
						for ($i=0; $i<$n; $i++) {
							$productArray[$i]['product_is_always_free_shipping'] = $products[$i]['product_is_always_free_shipping'];
						}
						break;
					case 'NOTIFY_HEADER_END_CHECKOUT_CONFIRMATION':
						global $order;
						for ($i=0; $i<$n; $i++) {
							$order->products[$i]['product_is_always_free_shipping'] = $products[$i]['product_is_always_free_shipping'];
						}
					default:
				}
			}
		}
	}
}

Create "/includes/auto_loaders/config.freeShippingObserver.php"

<?php
if (!defined('IS_ADMIN_FLAG')) {
	die('Illegal Access');
}

$autoLoadConfig[10][] = array(
	'autoType'=>'class',
	'loadFile'=>'observers/freeShippingObserver.php'
);
$autoLoadConfig[200][] = array(
	'autoType'=>'classInstantiate',
	'className'=>'freeShippingObserver',
	'objectName'=>'freeShippingObserver'
);

Then in the templates for those four pages one can look use:

if($cart_includes_free_shipping_product) { // Do something }

In the shopping cart template (inside the foreach starting at line 63) one can use:

if($product['product_is_always_free_shipping'] == '1') { // Do something }

In the checkout_confirmation template one can use:

if($order->products[$i]['product_is_always_free_shipping'] == '1') { // Do something }
