Weird! I use Notepad++ to create bp-custom.php and I add only the codes you provide, no other codes. I just tried again and it let my whole site become completely blank.
Or, is there any available plugin which can do the same thing? Thanks very much for your very kind help in this case!!!
Yes, I have read codex abot bp-custom. I also have added php tag as below.
<?php
// hide friendship activity stream sitewide
function bpfr_maybe_hide_friends_nav_etc() {
$retval = false;
if ( bp_is_user() && ! bp_is_my_profile() && ! friends_check_friendship( bp_displayed_user_id(), bp_loggedin_user_id() ) ) {
$retval = true;
}
return $retval;
}
function bpfr_hide_friends_nav_to_non_friends() {
// Stop if condition is not filed
if ( ! bpfr_maybe_hide_friends_nav_etc() ) {
return;
}
// otherwise, we remove the nav
bp_core_remove_nav_item( 'friends' ); // bp topnav
bp_core_remove_subnav_item( 'activity', 'friends' ); //bp subnav (my activities, my groups, etc)
}
add_action( 'bp_ready', 'bpfr_hide_friends_nav_to_non_friends' );
// we want also to remove all friends related activities to non friends
function bpfr_hide_friends_activity_type_to_non_friends( $activity_action = array(), $component_id = '' ) {
// if condition is not filed we go back to original output
if ( 'friends' != $component_id || ! bpfr_maybe_hide_friends_nav_etc() ) {
return $activity_action;
}
// otherwise, we remove member from context
$activity_action['context'] = array_diff( $activity_action['context'], array( 'member' ) );
return $activity_action;
}
add_filter( 'bp_activity_set_action', 'bpfr_hide_friends_activity_type_to_non_friends', 10, 2 );
?>
