@fearthemoose, @rezbiz,

Here “the best guarded secret” finally revealed !
But it’s not a secret, is part of Codex and a multi handled topic subject on this forum.

What we want to do: remove access possibility.
Where: on BuddyBar navigation menu (the one below the profile header).
Specifics: make the activity and forum tabs only visible to the logged in user.

NOTE: The activity tab is shown by default when you visit a profile.

As we are going to hide/remove this tab to visitors, we need to define as first another default tab. If we won’t do that, the visitor will get a Page not found error. Which is not exactly the case here, the page exist but the visitor can’t access it.

Let’s define arbitrary Profile as the new default tab. You can of course define what ever other existing tab on your BuddyBar as default.

Add this line to bp-custom.php
define( 'BP_DEFAULT_COMPONENT','profile' );

Now the mega “open secret” !

The folowing snippet contains almost any BP menu items you can have on a BuddyBar, and includes also the Forum item, in case you use bbPress.
You can remove or comment out those you don’t want to use.
Note also that it is only an example – you have to play with it to fit your need. But at least you have the right syntax to use.
Note also that some profile menu items are user only, such as message or notice. In other words, these are always private.

This function goes preferably to bp-custom.php

function bpfr_hide_tabs() {
global $bp;
	 /**
	 * class_exists() & bp_is_active are recommanded to avoid problems during updates 
	 * or when Component is deactivated
	 */

	if( class_exists( 'bbPress' ) || bp_is_active ( 'groups' ) ) :
        
        /** here we fix the conditions. 
        * Are we on a profile page ? | is user site admin ? | is user logged in ?
        */
	if ( bp_is_user() && !is_super_admin() && !is_user_logged_in() ) {

        /* and here we remove our stuff ! */
		bp_core_remove_nav_item( 'activity' );
		bp_core_remove_nav_item( 'friends' );
		bp_core_remove_nav_item( 'groups' );
		bp_core_remove_nav_item( 'forums' );
	}
	endif;
}
add_action( 'bp_setup_nav', 'bpfr_hide_tabs', 15 );

Some other hints for privacy
if you want to allow only the profile owner to view some tabs, replace
!is_user_logged_in by !bp_is_my_profile() – this scenario doesn’t need a check for logged in users as it is made by bp_is_my_profile.

If you want only to make a profile private, read here.

If you want to remove a sub-nav item (ie. View on Profile), you use something like:
bp_core_remove_subnav_item( 'profile', 'view' );

Many other possibilities for navigation are also available, including for groups. Several examples are given on Codex, here.

And if not enough, RTFM and search the forum ! 🙂

Have fun !

Hi @rezbiz,

in brief, you want to add some status dependent custom link to the BuddyBar.

I’ll ignore Kleo (premium theme) and Visual Composer (third party plugin).

Following examples let you add an external link to a non BP page on almost any menus (except BP usermenu).

How it works ?
– create a test page and call it Book.
– the page slug must be /book/
– the link (tab/button) will be displayed to logged-in users only.

I made also a snippet which add such a link to the WordPress Main Menu. This menu is the one you see in WP’s menu customizer by default. Depending the theme you use, you have always a main menu and X others. This can vary and it’s to you to find how it can/should work eventually. See theme documentation and WP Codex if you get in trouble with it.
Note that it should work with all Twenty themes at least.

Add the snippets to bp-custom.php and see the result. After that, read through the code and modify the page name/ID and slug to your need. Leave anything else untouched.

// add Custom tab on site wide activity and members directory pages
function tab_custom_link_to_page() {

	if ( bp_is_activity_component() || bp_is_page( BP_MEMBERS_SLUG ) ) {

		if ( !is_user_logged_in() )
			return false;

		// link to what you want
		$link = bp_get_root_domain() . '/book';

		echo'<li><a href="'. $link .'">My Book</a></li>'; 
	}
  
}
add_action( 'bp_activity_type_tabs', 'tab_custom_link_to_page' ); // site wide activity page
add_action( 'bp_members_directory_member_types', 'tab_custom_link_to_page' ); // members directory page

// add Custom tab on Profile Nav
function add_profiles_link_to_page(){

	if ( bp_is_profile_component() || bp_is_user() ) {

	if ( !is_user_logged_in() )
		return false;

	$link = bp_get_root_domain() . '/book/';

	?>
		<li><a href="<?php echo $link; ?>"><?php printf( 'My Book' ); ?></a></li>
	<?php  
	}
}
add_action( 'bp_member_options_nav', 'add_profiles_link_to_page' );

// add Custom tab on Groups Nav
function add_groups_link_to_page(){

if( bp_is_active( 'groups' ) ) {

	if ( !is_user_logged_in() )
		return false;

	$link = bp_get_root_domain() . '/';

	bp_core_new_subnav_item( array(
		'name'			=> 'My Book',
		'slug'			=> 'book',
		'parent_slug'		=> bp_get_current_group_slug(),
		'parent_url'		=> $link,
		'screen_function'	=> true, 
		'position'		=> 40 ) );
	}
}
add_action( 'bp_setup_nav', 'add_groups_link_to_page' );

// add Custom tab on Groups Directory
function add_groups_directory_link_to_page() {

	if( bp_is_active( 'groups' ) ) {

	if ( !is_user_logged_in() )
		return false;
 
    if ( bp_is_current_action( 'custom' ) ) 
        return;
 
	$link = bp_get_root_domain() . '/book';

    $button_args = array(
        'id'         => 'my-books',
        'component'  => 'groups',
        'link_text'  => 'My Book',
        'link_title' => 'My Book',
        'link_class' => 'my-books no-ajax',
        'link_href'  => $link,
        'wrapper'    => false,
        'block_self' => false,
    );  
   
    ?>
		<li><?php echo bp_get_button( apply_filters( 'bp_get_group_custom_button', $button_args ) ); ?></a></li>
    <?php
	}	
}
add_action( 'bp_groups_directory_group_filter', 'add_groups_directory_link_to_page' );

// add Custom tab on WP Main Menu ( after Home, About, etc )
function main_menu_custom_link_to_page( $menu ) { 
     
	if ( !is_user_logged_in() )
			return $menu;
	else
 	// link to what you want
	$link = bp_get_root_domain() . '/book';

	$grouplink = '<li><a href="'. $link . '">My Book</a></li>';

	$menu = $menu . $grouplink;
	return $menu;
}
add_filter( 'wp_nav_menu_items', 'main_menu_custom_link_to_page' );

Yes, it looks complicated, but it isn’t. Simply it’s not homogeneous ! 🙂

and thank you beforehand, @danbp
