Ajouter un élément de menu personnalisé à l'aide du filtre wp_nav_menu_items

J'ai ajouté un extrait pour ajouter un lien "Profil" au menu de navigation de mon site Web. Mon code:

add_filter( 'wp_nav_menu_items', 'my_nav_menu_profile_link');
function my_nav_menu_profile_link($menu) {  
    if (!is_user_logged_in()){
         return $menu;
    } else {
         $user_data = bbp_get_user_profile_url( get_current_user_id() );
         $profilelink = '<li><a href="'.$user_data.'&edit" >Profile</a></li>';
         $menu = $menu . $profilelink;
         return $menu;
    }
}

Ce code affiche correctement le lien de profil dans mon menu, mais maintenant je veux déplacer ce lien "profil" comme sous-menu d'un autre menu principal.

Ma structure de menu est la suivante:

Accueil | Mon compte | Les catégories

Je voudrais ajouter le lien "profil" sous "Mon compte". Des suggestions pour résoudre ce problème?

J'ai créé ces deux fonctions que vous pouvez utiliser pour ajouter des éléments personnalisés à un élément de menu donné présent dans votre menu (page, publication, lien ...).

Dans votre cas, vous pouvez ajouter ces fonctions à votre functions.php et les appeler comme ceci:

$menu_name = 'Your Menu Name';
$name_of_menu_item_to_append_to = 'My Account';
$id_of_menu_item_to_append_to =  get_wp_object_id( $name_of_menu_item_to_append_to, 'nav_menu_item' );
$new_submenu_item = array(
    'text' => 'Profile',
    'url'  => 'http://someurl.com'
);

add_subitems_to_menu( 
    $menu_name,
    $id_of_menu_item_to_append_to,
    array( $new_submenu_item ) 
);
