I try to create a menu item for every new product category created, but it just creates an empty custom menu item (in the right place). If I however don't assign a menu-item-parent-id it works fine (but not in the right place obviously).
function add_product_category_to_menu($term_id, $tt_id, $taxonomy) {
if ($taxonomy === 'product_cat') {
$term = get_term($term_id, $taxonomy);
$menu_name = 'main-menu';
$menu = wp_get_nav_menu_object($menu_name);
if ($menu) {
$menu_id = $menu->term_id;
$term_name = $term->name;
function get_parent_menu_item_id_by_name($parent_id, $menu_id) {
$parent_term = get_term($parent_id, 'product_cat');
$menu_items = wp_get_nav_menu_items($menu_id);
foreach ($menu_items as $menu_item) {
if (trim($menu_item->object_id) === trim($parent_term->term_id)) {
return $menu_item->ID;
}
}
}
$menu_item_id = wp_update_nav_menu_item($menu_id, 0, array(
'menu-item-title' => $term_name,
'menu-item-object-id' => intval($term_id),
'menu-item-object' => 'product_cat',
'menu-item-type' => 'taxonomy',
'url' => get_term_link($term),
'menu-item-status' => 'publish'
));
// If the category has a parent, update its parent ID
if (!empty($term->parent) && $term->parent != 0) {
$parent_term = get_term($term->parent, 'product_cat');
if (!is_wp_error($parent_term)) {
$parent_menu_item_id = get_parent_menu_item_id_by_name($parent_term, $menu_id);
error_log('Parent Menu ID: ' . $parent_menu_item_id);
wp_update_nav_menu_item($menu_id, $menu_item_id, array(
'menu-item-parent-id' => $parent_menu_item_id
));
}
}
error_log('Term ID: ' . $term_id);
$menu_items = wp_get_nav_menu_items($menu_id);
foreach ($menu_items as $menu_item) {
if ($menu_item->ID == $menu_item_id) {
error_log('Item Object ID: ' . print_r($menu_item, true));
break;
}
}
}
}
}
add_action('create_term', 'add_product_category_to_menu', 10, 3);

Reset to default 3Update
Solution was easy I'm stupid I just tweaked the menu creation and directly assigned the parent-menu-id:
if (!empty($term->parent) && $term->parent != 0) {
$parent_menu_item_id = get_parent_menu_item_id_by_name($term->parent, $menu_id);
if ($parent_menu_item_id) {
$menu_item_id = wp_update_nav_menu_item($menu_id, 0, array(
'menu-item-title' => $term_name,
'menu-item-object-id' => intval($term_id),
'menu-item-object' => 'product_cat',
'menu-item-type' => 'taxonomy',
'url' => get_term_link($term),
'menu-item-parent-id' => $parent_menu_item_id,
'menu-item-status' => 'publish'
));
} else {
$menu_item_id = wp_update_nav_menu_item($menu_id, 0, array(
'menu-item-title' => $term_name,
'menu-item-object-id' => intval($term_id),
'menu-item-object' => 'product_cat',
'menu-item-type' => 'taxonomy',
'url' => get_term_link($term),
'menu-item-status' => 'publish'
));
}
}
