BuddyPress Admin Only Profile Fields

DUK

How do I hide a profile field?

In the WordPress admin area, go to Users > Profile Fields and click Edit on the desired profile field. Under the Default Visibility panel select Hidden as the value and click Save.

The profile field is now hidden from all users except Administrators.

How do I change who can view and edit the hidden field?

Add the following filter to your theme’s functions.php file, substituting edit_others_posts with the desired capability:
function custom_profile_fields_visibility() {
return ‘edit_others_posts’; // Editors
}
add_filter( ‘bp_admin_only_profile_fields_cap’, ‘custom_profile_fields_visibility’ );
