The $menu_item_data argument accepts an array of data. Depending upon the type of nav menu item you are attempting to add, it requires different parameters:

Note that in several cases, menu-item-object must be included, and it must be set to the post type of the nav item you are referencing.

Page

$page = get_post(123); // etc wp_update_nav_menu_item($menu_id, 0, array( 'menu-item-title' => 'My Link', 'menu-item-object-id' => $page->ID, 'menu-item-object' => 'page', 'menu-item-status' => 'publish', 'menu-item-type' => 'post_type', ));

Post

$post = get_post(123); // etc wp_update_nav_menu_item($menu_id, 0, array( 'menu-item-title' => 'My Link', 'menu-item-object-id' => $post->ID, 'menu-item-object' => 'post', 'menu-item-status' => 'publish', 'menu-item-type' => 'post_type', ));

Custom

When adding a custom link to your nav menu, you can omit the menu-item-type because it defaults to custom.

wp_update_nav_menu_item($menu_id, 0, array( 'menu-item-title' => 'My Link', 'menu-item-url' => 'http://example.com/', 'menu-item-status' => 'publish', 'menu-item-type' => 'custom', // optional ));

internetfootprint 4 years ago

When adding a link for a custom post type.

In addition to the other minimum required parameters, pass these values to the $menu_item_data parameter:

'menu-item-object'	=> 'your-registered-post-type-name', // i.e., foo-bar, foo_bar, 'event-scheduler' 'menu-item-type'	=> 'post_type', // For example: $menu_item_data = [	'menu-item-object-id' => $post->ID, // Or however, you get the post's id.	'menu-item-object' => 'wpdocs-foo-bar',	'menu-item-type' => 'post_type',	'menu-item-status' => 'publish',	'menu-item-title' => esc_html__( 'It\'s all Foo Bar' ),	'menu-item-description' => esc_html__( 'Page about how, It\'s all Foo Bar' ),	'menu-item-classes' => 'wpdocs-foo-bar', ]; wp_update_nav_menu_item( $menu_id, 0, $menu_item_data )

Example on how to work with taxonomies: automatically add a new menu item when a new woocommerce product category has been created. Also if it’s a subcategory – add it as a respective subitem.

// on woocommerce product category creation add it to menu: add_action( 'create_product_cat', 'wpdocs_add_menu_item_on_create_product_cat' ); function wpdocs_add_menu_item_on_create_product_cat( $term_id ) {	// get target menu from menu location:	$menu_ids = get_nav_menu_locations();	$menu_id = $menu_ids['menu-1'];	$args = array(	'menu-item-object-id' => $term_id,	'menu-item-object' => 'product_cat',	'menu-item-type' => 'taxonomy',	'menu-item-status' => 'publish',	);	// also check if current category is a subcategory, and if so,	// if it's parent category has a menu item - then assign current item	// as a subitem to that:	$parent_term_id = get_term_field( 'parent', $term_id, 'product_cat', 'raw' );	if ( $parent_term_id ) {	$parent_term_menu_item = get_posts( array(	'numberposts' => 1,	'post_type' => 'nav_menu_item',	'meta_key' => '_menu_item_object_id',	'meta_value' => $parent_term_id,	'fields' => 'ids'	) );	if ( ! empty( $parent_term_menu_item ) ) {	$args['menu-item-parent-id'] = $parent_term_menu_item[0];	}	}	wp_update_nav_menu_item( $menu_id, 0, $args ); }

If you’re updating an existing menu item and want to keep the ordering, pass 'menu-item-position'. Otherwise, the item will move to the end of the menu.
```
$menu_item_data = array( 'menu-item-position' => $item->menu_order, 'menu-item-parent-id' => $item->menu_item_parent, 'menu-item-type' => 'custom', 'menu-item-url' => $url, 'menu-item-title' => $item->title, 'menu-item-status' => $item->post_status, );
