Hi, I would like to display nickname (and not username) in the whole bbpress forum.

For topics list, I modified the code from a previous topic Show username instead of full name / display name and it works well so far.

See https://paste.pics/MVA62

The modified codes that I use is as follows:

add_filter( 'bbp_get_reply_author_display_name' , 'rew_reply_change_to_nickname', 10 , 2 ) ;

function rew_reply_change_to_nickname ($author_name, $reply_id) {
	// Get the author ID
	$author_id = bbp_get_reply_author_id( $reply_id );
	$nickname = um_get_display_name( $author_id );
return $nickname ;
}

add_filter( 'bbp_get_topic_author_display_name' , 'rew_topic_change_to_nickname', 10 , 2 ) ;

function rew_topic_change_to_nickname ($author_name, $topic_id) {
	// Get the author ID
	$author_id = bbp_get_topic_author_id( $topic_id );
	$nickname = um_get_display_name( $author_id );
return $nickname ;
}

Note: I use Ultimate Member (UM) plugin to display user details.

However, when comes to user profile, I’m struggling on how to force display nickname right above the avatar. Hope you can help me with that.

Note: It’s very tedious to modify “display name publicly as” from the WordPress dashboard for every registered user. Thus hopefully codes may well do the job for me.

A link to your website/forum can be helpful. Most probably, this header is coming from your theme.

Hi, here is my test site. Still under construction.

I found that most of the time WordPress display correctly in “display name publicly as” using NICKNAME. But there are times where it displays USERNAME in “display name publicly as” even though users have already registered their nickname in Ultimate Member profile.

As I guessed, it’s coming from your theme

You can try this: (it’s not tested)

function aa_profile_title ( $title, $id ) {

        if ( bbp_is_single_user_profile() && empty(get_post_type($id)) ) {

                $author_id = bbp_get_displayed_user_field('ID');
                $nickname = um_get_display_name( $author_id );
                $title = $nickname;
        }
        return $title;
}       
add_filter( 'the_title', 'aa_profile_title', 10, 2);
