WooCommerce - get category for product page

📢 Hey there WooCommerce enthusiasts! Are you struggling to get the category ID for your product pages on WooCommerce? Do you need to add a custom class to the body tag for some unique styling? 🤔 Well, fret no more! We've got you covered with some easy solutions that will have your WooCommerce pages looking snazzy in no time! 💃💥

So, let's dive right in and solve this puzzling problem! 🧩

The Challenge: Getting the WooCommerce Category ID

In our lovely community, a fellow developer found themselves in a bit of a conundrum. They were working on their WooCommerce product pages and wanted to add a specific class to the body tag to apply some custom CSS styling. However, they were scratching their head wondering how to fetch the WooCommerce category ID for each individual product page dynamically. 🤷‍♂️

The Solution: Unveiling the WooCommerce Category ID

WooCommerce provides various handy functions and methods for fetching product-related information, and luckily, there's a straightforward solution to our problem! 🎉

To get the WooCommerce category ID for a product page, you can utilize the get_the_terms() function, which retrieves the terms associated with a specific post (in this case, a product page). By passing the product's ID and the 'product_cat' taxonomy as parameters, we can obtain the WooCommerce category ID effortlessly.

Here's the magic code snippet that will do the trick: 👇

function my_add_woo_cat_class($classes) {
    global $post;

    if (is_product()) {
        $terms = get_the_terms($post->ID, 'product_cat'); 

        // Ensure that we have terms and the first term exists
        if ($terms && !is_wp_error($terms) && !empty($terms[0])) {
            $wooCatIdForThisProduct = $terms[0]->term_id;
            $classes[] = 'my-woo-cat-id-' . $wooCatIdForThisProduct;
        }
    }

    return $classes;
}

Let's Break it Down

1. We start by defining our my_add_woo_cat_class function and passing the $classes parameter, where we will store our custom class.

2. We use the global $post variable to get the post ID of the current product page.

3. We then check if we are indeed on a product page using the is_product() function.

4. Next up, we utilize get_the_terms($post->ID, 'product_cat') to retrieve the terms associated with the current product using the 'product_cat' taxonomy.

5. We do some additional checks to ensure that we have valid terms available.

6. Finally, if everything checks out, we assign the WooCommerce category ID to the $wooCatIdForThisProduct variable and add our custom class to the $classes array.

And that's it! You now have the WooCommerce category ID at your disposal, ready to be used for your custom styling needs. 😎

Don't forget to add the filter to apply the class to the body tag. Here's the code for that:

if (is_product()) {
    add_filter('body_class','my_add_woo_cat_class');
}

Bring on the Styling Magic! ✨✨

With the WooCommerce category ID in hand, you can now dazzle your WooCommerce product pages with some truly amazing custom CSS effects. Tailor your designs to complement each category or create cohesive themes across similar product pages. The possibilities are endless! 🔮🎨
