I'm pretty desperate here, as my search for an answer has led me nowhere, and none of my code seems to work the way I think it should.
I'm trying to add a custom class to the body tag whenever I'm on a product category page. I need this to be a function inside functions.php. I've tried everything from if(is_category()) to if(is_post_type('product')) and every variation I can think of, but NOTHING works. Is there anyone who can help me with this??
