I'm currently working on a WooCommerce theme and attempting to add a sidebar to the product detail page.
I've been able to get the sidebar added (specifically, this one: http://woocommerce.wp-a2z.org/oik_file/templatescontent-widget-product-php/)
Now, I'm trying to figure out how to add a class of "active" to the currently selected product and can't seem to figure it out?
In other words, how do I do something along the lines of if the current product id is equal to the product id in the sidebar add class="active" to the li?
I've made numerous searches and haven't been able to come up with anything useful, so I'm turning here.
Any help greatly appreciated!!
2017 Update - since WooCommerce 3:
global $product;
$id = $product->get_id();
Woocommerce doesn't like you accessing those variables directly. This will get rid of any warnings from woocommerce if your wp_debug is true.
