I have added a snippet to add a "Profile" link to my website navigation menu. My 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;
    }
}

This code correctly display profile link in my menu, but now I want to move this "profile" link as sub menu of another main menu.

My Menu structure is as follows:

Home | My Account | Categories

I would like to add "profile" link under "My Account". Any suggestions to solve this problem?

@bestprogrammerintheworld - that's for admin menu, not the front-end menu. –  Stephen Harris May 4 at 9:30

I've created these two functions you may use to add custom items to a given menu item present in your menu (page, post, link...).

In your case, you can add these function to your functions.php and call them like this:

$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 ) 
);

add_subitems_to_menu()

/**

public function add_subitems_to_menu( $menu_name, $parent_object_id, $subitems ) {
    // Don't add anything in admin area. Otherwise WP will try to display the items in the 
    // Menu editor and it won't work fine and cause strange behaviour
    if ( is_admin() ) {
        return;
    }

    // Use wp_get_nav_menu_items filter, is used by Timber to get WP menu items
    add_filter( 'wp_get_nav_menu_items', function( $items, $menu )

Thank you MikO for your help 1. My Account is not page, I have craeted a link and added it to menu through wp admin menu settings 2. I have checked your code by creating a new page and by passing its id to function, but didn't work for me 3. I have changed line $my_account_page_id = into $my_account_item_id –  Hafsal May 4 at 13:58
    
I have added all your code in function.php –  Hafsal May 4 at 14:05
    
Ohh Miko, It is working now, Thank you very much for the code.. But Instead of using page id, i would like to add Profile under a link, which i have created in wp admin menu settings –  Hafsal May 4 at 14:12
    
No probs, I got custom menu item id by checking in db So it is fixed, Thanks again –  Hafsal May 4 at 14:56
    
@Hafsal, you're welcome. I edited my answer adding antoher function, which you can use to get the ID of any WordPress page, post or menu item, and I updated the way you should call these functions. Otherwise, you can check directly the ID in the DB as you've done... –  MikO May 4 at 15:00
