Shortcode to show the parent taxonomy in woocommerce

To create a shortcode that displays the parent taxonomy name in WooCommerce, you can use the following code:

// Register the shortcode
function display_parent_taxonomy_shortcode() {
    add_shortcode('parent_taxonomy', 'get_parent_taxonomy');
}
add_action('init', 'display_parent_taxonomy_shortcode');

// Callback function for the shortcode
function get_parent_taxonomy() {
    // Check if we are on a product category archive page
    if (is_product_category()) {
        global $wp_query;

        // Get the current category object
        $category = $wp_query->get_queried_object();

        // Get the parent category ID
        $parent_id = $category->parent;

        // If the parent ID is greater than 0, get the parent category
        if ($parent_id > 0) {
            $parent_category = get_term($parent_id, 'product_cat');
            $parent_name = $parent_category->name;

            // Return the parent category name
            return $parent_name;
        }
    }

    // If not on a product category archive page or parent category not found, return an empty string
    return '';
}

You can add the above code to your theme’s functions.php file or create a custom plugin for it. This code registers a shortcode called [parent_taxonomy] and defines a callback function called get_parent_taxonomy.

When the shortcode is used, it checks if the current page is a product category archive page. If it is, it retrieves the parent category’s name and returns it. If there is no parent category or if the current page is not a product category archive, it returns an empty string.

To display the parent taxonomy name (“Fruits”) on the “Healthy Fruits” product archive page, you can simply add the [parent_taxonomy] shortcode in your desired location within the WordPress editor or a template file. For example:

<p>The parent taxonomy is: [parent_taxonomy]</p>

When this shortcode is used on the “Healthy Fruits” product archive page, it will output:

The parent taxonomy is: Fruits

Please note that this code assumes you are using the default “product_cat” taxonomy for product categories in WooCommerce. If you have a custom taxonomy, you’ll need to modify the code accordingly by replacing 'product_cat' with the appropriate taxonomy slug.
