How to Get the Current Product ID in WooCommerce

In WooCommerce, obtaining the current product ID on the product detail page can be essential for tasks such as highlighting the active product in a sidebar. By leveraging the global $product variable and its get_id() method, you can easily retrieve the product identifier.

To illustrate:

global $product;
$id = $product->get_id();

Prior to WooCommerce version 3, accessing product variables could trigger warnings. However, this approach ensures compatibility even if wp_debug is enabled. By utilizing this method, you can now efficiently add the desired "active" class to the current product in your sidebar.
