I want go get the SKU in my product single pages in Woocommerce. I tried <?php get_sku(); ?> which is a featured function according to the Woocommerce docs (http://docs.woothemes.com/wc-apidocs/class-WC_Product.html) but it will just break the loop. What to do?
get_sku() is a method of the WC_Product class, so you need to have a product on which to call it, like this:
<?php echo $product->get_sku(); ?>
This should work if you are inside the WooCommerce product loop, and is what is used in the WooCommerce template files. If you don't already have a reference to the product object, you may need to add the following line at the top of the file in order to access it:
global $product;
