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

LOOOL, lhungil, talk about a simple solution... Now I wish I had a time machine and go just a few hours back to stop me from hitting my head... So, what do you do when you're not browsing the forums, teach Rocket Science over at MIT?

Although this is a brilliant solution (as most coming from you are), isn't it a bit of an overkill for the purpose? Personally, I'd use your first solution with in_cart_check and just put the results (conditional, of course) into $_SESSION for it to be used on any other inner page...

I might be missing something obvious here, but still - IMHO, a much simpler approach, and (possibly more important) understandable by most mortals, not just you MIT gals...

LOL, I definately have been enjoying reading your posts as of late. The humour (and possibly sarcasm) lately has been a very welcome beathe of fresh air.

As for my reasons... I have an aversion to modifying core files... Mostly because I spent WAY too much time merging during my last few ZC upgrades...

And since Zen Cart has an existing design pattern for just such a purpose, I figured "Why not"?

I am sadly gonna have to agree and admit defeat.. Perhaps over the weekend, I'll spend some time trying to see if I can interpret lhungil's solution, but it's WAAAAY over my head to "figure out" on my own.... Your solution worked, and for now that's what I'm gonna go with 'cause I've got one other issue with this site launch to contend with that's giving me fits.. All my free shipping needs are firing on all cylinders now..

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


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 }
