It excludes the "Uncategorized" category.** How it works:* 1. Fetches the WooCommerce menu with the name "Categories".* 2. Iterates through all product categories in the taxonomy 'product_cat'.* 3. Adds top-level categories to the menu if they do not already exist.* 4. Recursively adds child categories under their respective parent categories.* 5. Skips the "Uncategorized" category to avoid clutter in the menu.* * Hooks:* - Runs on `create_product_cat` and `edited_product_cat` actions to ensure the menu stays updated.** Usage:* - Ensure the menu named "Categories" exists in your WordPress site.* - Ensure you have already add manually the first level parent "Categories" (if not, it still works)* - Categories will be dynamically added, preserving parent-child relationships.* - Existing menu items are reused to prevent duplication.** Credits:* - Developed by Nicolas Lagios* - Website: https://nicolaslagios.com* - Donations: https://paypal.me/nicolaslagios*/function update_woocommerce_categories_menu() { $menu_name = 'Categories'; $menu_exists = wp_get_nav_menu_object($menu_name); if (!$menu_exists) { return; // Exit if the menu does not exist. } $menu_id = $menu_exists->term_id; // Fetch all product categories $product_categories = get_terms(array( 'taxonomy' => 'product_cat', 'hide_empty' => false, 'orderby' => 'name', 'order' => 'ASC' )); // Helper function to find a menu item by term ID function find_menu_item_id_by_category($category, $menu_id) { $menu_items = wp_get_nav_menu_items($menu_id); if ($menu_items) { foreach ($menu_items as $menu_item) { if ($menu_item->object_id == $category->term_id && $menu_item->object == 'product_cat') { return $menu_item->ID; // Return the menu item ID } } } return 0; // Return 0 if not found } // Recursive function to add categories function add_category_to_menu($category, $menu_id, $parent_id = 0) { // Skip the "Uncategorized" category if ($category->slug === 'uncategorized') { return; } // Check if this category is already in the menu $existing_menu_item_id = find_menu_item_id_by_category($category, $menu_id); if (!$existing_menu_item_id) { // Add category to the menu $menu_item_id = wp_update_nav_menu_item($menu_id, 0, array( 'menu-item-title' => $category->name, 'menu-item-url' => get_term_link($category), 'menu-item-status' => 'publish', 'menu-item-type' => 'taxonomy', 'menu-item-object' => 'product_cat', 'menu-item-object-id' => $category->term_id, 'menu-item-parent-id' => $parent_id )); } else { $menu_item_id = $existing_menu_item_id; // Use existing menu item ID } // Get child categories $children = get_terms(array( 'taxonomy' => 'product_cat', 'hide_empty' => false, 'parent' => $category->term_id )); foreach ($children as $child) { add_category_to_menu($child, $menu_id, $menu_item_id); // Recursively add children } } // Add top-level categories and their children foreach ($product_categories as $category) { if ($category->parent == 0 && $category->slug !== 'uncategorized') { // Top-level category and not "Uncategorized" add_category_to_menu($category, $menu_id); } }}// Run the function when product categories are created or updatedadd_action('create_product_cat', 'update_woocommerce_categories_menu');add_action('edited_product_cat', 'update_woocommerce_categories_menu'); |
