Observer Notifier NOTIFIER_CART_GET_PRODUCTS_END Help

[Celtic]

Hi all knowledgeable and intellectually imbued peoples

I would like to sort the contents of my shopping cart alphabetically by name. I know how to do this by modifying the core file (/includes/classes/shopping_cart.php) as I've shown here: http://www.zen-cart.com/forum/showthread.php?t=181068

As I've just begun to look into using observers/notifiers I figured I should write it properly so as not to modify core files.

Now I'm totally stumped!!!

From the other thread, you can see that I need to do a sort on the values in array $products_array before it is returned by the get_products() method.

I am tying into NOTIFIER_CART_GET_PRODUCTS_END that is triggered just before the $shopping_cart->get_products method returns the $products_array content.



1) How can I get access to the $products_array content from within my observer class so that I can run the sort on it?

2) How can I pass the newly sorted array back into $shopping_cart->get_products so that it returns the sorted cart details back to its original calling source?

3) Or should I be approaching this completely differently?

Thanks,
Celtic

In your shopping_cart class I think you'll need to change the 3 references to $products_array to $this->products_array instead, and then it'll be available for manipulation in your observer class and any changes you make to it will pass back automatically.

Thanks DrB, but that's a no-go unfortunately.

Here's what I've got in the update method...

    function update( &$class, $eventID, $paramsArray ) {
            echo "one...";
            print_r($class->products_array);
            echo "...two...";
            print_r($this->products_array);
            echo "...three...";
            print_r($products_array);
            echo "...four...";
            global $products_array;
            print_r($products_array);
            echo "...done!";
            //exit;
            //return "YO DUDE!";
    } 

Any other thoughts?

Thanks,
