WooCommerce: Category as “Body” Class @ Single Product Page

A Business Bloomer fan asked me an interesting question this week: how to apply CSS on the single product page based on the product category? Well, the answer is pretty simple: if we’re able to add the category name to the HTML “body”, this can then be targeted in your custom CSS. So, let’s see how this is done!

PHP Snippet: Add WooCommerce Product Category as Body CSS Class @ Single Product Page

Thankfully, there was already some literature available on GitHub, and despite being 5 years old it still works like a charm. So, many thanks Michael Krapf ๐Ÿ™‚

add_filter( 'body_class', 'bbloomer_wc_product_cats_css_body_class' );
 
function bbloomer_wc_product_cats_css_body_class( $classes ){
  if ( is_singular( 'product' ) ) {
    $current_product = wc_get_product();
    $custom_terms = get_the_terms( $current_product->get_id(), 'product_cat' );
    if ( $custom_terms ) {
      foreach ( $custom_terms as $custom_term ) {
        $classes[] = 'product_cat_' . $custom_term->slug;
      }
    }
  }
  return $classes;
}

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7+.

  1. Any advice on how to do this in the cart and checkout pages, so that it adds classes of the product category based on what items are in the cart/checkout?

    1. Hi Jon, thanks so much for your comment! Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!

  2. Still working, thank you for the help.

    1. Cheers!

  3. Nice one! I would be interested how that that works with woocommerce product tags instead of categories. Any hints are welcome ๐Ÿ™‚

    1. Rainer, thanks so much for your comment! Yes, this is possible – but unfortunately this is custom work and I cannot provide a complementary solution here via the blog comments. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding! ~R

  4. Works like a charm ๐Ÿ˜‰ Thanks!

    1. Nice ๐Ÿ™‚

  5. Absolutely fantastic! Works beautifully ๐Ÿ™‚

    1. Awesome ๐Ÿ™‚

  6. Fine.
    My problem is to add a small CSS code to be used only in category page.
    The theme I use has a problem and don’t give to me this opportunity, so I wish to use functions.php

    This is my code:
    .shop-page-title { height:300px !important; max-height:300px !important; }

    1. Hey Giancarlo, you can definitely target the “archive” pages via CSS only ๐Ÿ™‚

  7. Hi,
    Thank you so much for your helpful blogs and videos. I wish to change the colour & logo image in my menu navigation on my product category page and single products in that category. How can I edit this to include the product category page also?

    Thank you ๐Ÿ™‚

    1. Hey Rachael thanks so much for your comment! Once the category is in the class, you can do whatever you like with CSS on that specific page – as you said this only works on the single product page. In fact, the category page already has a body class with the name of the category – so there is no need for us to add it; if you target that in your CSS you’ll be able to achieve what you like. Let me know!
