A drop-in for Wordpress which allows access to the shopping cart of OS Commerce when WP is installed in a sub-folder of OS Commerce.
At the moment this isn't a widget or plugin, you just include it it like this:
<?php $GLOBALS['OSC_CART_RETRIEVER_HOST'] = '127.0.0.1'; $GLOBALS['OSC_CART_RETRIEVER_USER'] = 'root'; $GLOBALS['OSC_CART_RETRIEVER_PASS'] = ''; $GLOBALS['OSC_CART_RETRIEVER_DB'] = 'osc-wp-test';
require_once('../osc_cart_retriever.php');
$r = new OscCartRetriever(); $cart = $r->retrieve(); ?>
<?php if(isset($cart)) { ?>
Total: total; ?>
