Gets the list of activity types name supporting the requested feature.

_bp_activity_get_types_by_support(string $feature = 'generated-content') : array

This function is still a WIP, please don't use it into your plugins or themes.

package BuddyPress
since 10.0.0
access private
todo `bp_activity_set_action()` should be improved to include a supports argument or best we should create a `bp_register_activity_type()` function to mimic the way WordPress registers post types. For now we'll use a non extendable workaround.

Parameters

$feature

string

The feature activity types should support.

Returns

arrayThe list of activity types name supporting the requested feature.

Injects specific BuddyPress CSS classes into a widget sidebar.

_bp_core_inject_bp_widget_css_class(array $params) : array

Helps to standardize styling of BuddyPress widgets within a theme that does not use dynamic CSS classes in their widget sidebar's 'before_widget' call.

Temporary implementation of 'bp_moderate' cap.

_bp_enforce_bp_moderate_cap_for_admins(array $caps = array(), string $cap = '', integer $user_id = 0, array $args = array()) : array

In BuddyPress 1.6, the 'bp_moderate' cap was introduced. In order to enforce that bp_current_user_can( 'bp_moderate' ) always returns true for Administrators, we must manually add the 'bp_moderate' cap to the list of user caps for Admins.

Note that this level of enforcement is only necessary in the case of non-Multisite. This is because WordPress automatically assigns every capability - and thus 'bp_moderate' - to Super Admins on a Multisite installation. See \WP_User::has_cap().

This implementation of 'bp_moderate' is temporary, until BuddyPress properly matches caps to roles and stores them in the database.

Plugin authors: Please do not use this function; thank you. :)

Backward compatibility for 'last_activity' usermeta fetching.

_bp_get_user_meta_last_activity_warning(null $retval, integer $object_id, string $meta_key, boolean $single) : string | null

In BuddyPress 2.0, user last_activity data was moved out of usermeta. For backward compatibility, we continue to mirror the data there. This function serves two purposes: it warns plugin authors of the change, and it returns the data from the proper location.

Remove WP's canonical redirect when we are trying to load BP-specific content.

_bp_maybe_remove_redirect_canonical() 

Avoids issues with WordPress thinking that a BuddyPress URL might actually be a blog post or page.

This function should be considered temporary, and may be removed without notice in future versions of BuddyPress.

package BuddyPress
since 1.6.0

Remove WP's rel=canonical HTML tag if we are trying to load BP-specific content.

_bp_nav_menu_sort(array $a, array $b) : integer

package BuddyPress

since 1.7.0

Parameters

Rehook maybe_redirect_404() to run later than the default.

_bp_rehook_maybe_redirect_404() 

WordPress's maybe_redirect_404() allows admins on a multisite installation to define 'NOBLOGREDIRECT', a URL to which 404 requests will be redirected. maybe_redirect_404() is hooked to template_redirect at priority 10, which creates a race condition with bp_template_redirect(), our piggyback hook. Due to a legacy bug in BuddyPress, internal BP content (such as members and groups) is marked 404 in $wp_query until bp_core_load_template(), when BP manually overrides the automatic 404. However, the race condition with maybe_redirect_404() means that this manual un-404-ing doesn't happen in time, with the results that maybe_redirect_404() thinks that the page is a legitimate 404, and redirects incorrectly to NOBLOGREDIRECT.

By switching maybe_redirect_404() to catch at a higher priority, we avoid the race condition. If bp_core_load_template() runs, it dies before reaching maybe_redirect_404(). If bp_core_load_template() does not run, it means that the 404 is legitimate, and maybe_redirect_404() can proceed as expected.

This function will be removed in a later version of BuddyPress. Plugins (and plugin authors!) should ignore it.
