The get_terms WordPress function is listing all your terms for a given taxonomy (or taxonomies).
However, the default callback returns only the terms with entries. Therefore your empty terms won’t be visible unless you use the hide_empty parameter with a false value, like this:
[php]
$product_terms = get_terms( ‘product’, array( ‘hide_empty’ => false ) );
[/php]
Passing the hide_empty parameter would fetch the empty terms from your product category as well.
