bp_core_menu_highlight_parent_page( array $retval, WP_Post $page )
Adds current page CSS classes to the parent BP page in a WP Page Menu.
Description Description
Because BuddyPress primarily uses virtual pages, we need a way to highlight the BP parent page during WP menu generation. This function checks the current BP component against the current page in the WP menu to see if we should highlight the WP page.
Parameters Parameters
- $retval
-
(Required) CSS classes for the current menu page in the menu.
- $page
-
(Required) The page properties for the current menu item.
Return Return
(array)
