bbPress.org

Put this code somewhere in your theme functions.php

https://gist.github.com/4086011

Otherwise you can change the roles editing the bbPress gettext file. Check ‘\wp-content\plugins\bbpress\bbp-languages\bbpress.pot’, create a .po for your language (if you already hasn’t one) and change the string “Key Master” at line 3311. If you don’t know what I’m talking about I can generate the file for you.

I’m having issues with this using 2.2 of the bbPress. I did edit the line you suggested but I don’t believe that it’s being handled in the same spot in the new release. Any thoughts?

Thanks Zearl, need to modify your code slightly to get it to work:
Had to remove ‘$user_role’

function my_custom_roles( $role, $user_id ) {
if( $role == ‘Key Master’ )
return ‘Site Owner’;
return $role;
}
add_filter( ‘bbp_get_user_display_role’, ‘my_custom_roles’, 10, 3 );

try this code from this link

https://gist.github.com/ntwb/7864894

and rename the ones you want

add_filter( 'bbp_get_dynamic_roles', 'ntwb_bbpress_custom_role_names' );

function ntwb_bbpress_custom_role_names() {
	return array(

		// Keymaster
		bbp_get_keymaster_role() => array(
			'name'         => 'My Custom Keymaster Role Name',
			'capabilities' => bbp_get_caps_for_role( bbp_get_keymaster_role() )
		),

		// Moderator
		bbp_get_moderator_role() => array(
			'name'         => 'My Custom Moderator Role Name',
			'capabilities' => bbp_get_caps_for_role( bbp_get_moderator_role() )
		),

		// Participant
		bbp_get_participant_role() => array(
			'name'         => 'My Custom Participant Role Name',
			'capabilities' => bbp_get_caps_for_role( bbp_get_participant_role() )
		),

		// Spectator
		bbp_get_spectator_role() => array(
			'name'         => 'My Custom Spectator Role Name',
			'capabilities' => bbp_get_caps_for_role( bbp_get_spectator_role() )
		),

		// Blocked
		bbp_get_blocked_role() => array(
			'name'         => 'My Custom Blocked Role Name',
			'capabilities' => bbp_get_caps_for_role( bbp_get_blocked_role() )
		)
	);
}

I wanted to change two titles, so I wrote this (had to take the translated strings though, so this fix will fail again when roles are renamed in bbress or our locale):

function my_custom_roles( $role, $user_id ) {
	if( $role == 'Teilnehmer' )
		return ' ';

	return $role;
	
}

add_filter( 'bbp_get_user_display_role', 'my_custom_roles', 10, 2 );

function my_custom_roles2( $role, $user_id ) {
	if( $role == 'Keymaster' )
		return 'Administrator';

	return $role;
}

add_filter( 'bbp_get_user_display_role', 'my_custom_roles2', 10, 2 );

Here’s the list of names as set by default: http://hookr.io/functions/bbp_get_dynamic_roles/

You should be able to use:

$roles = bbp_get_dynamic_roles();
$print_r( $roles );

to see what the names of your roles are.
