Show a display name instead of username

R_J

Forget everything else and add this two lines to your /conf/config.php:

$Configuration['Garden']['User']['ValidationRegex'] = '\\d\\w-_ äöüß';
$Configuration['Garden']['User']['ValidationLength'] = '{3,20}';

That way your users are able to choose whatever user name they like.
You only need the second line if you want to change the max. length of a name

If you want to give your users the ability to "fix" their names, add the following line to the config: $Configuration['Garden']['Profile']['EditUsernames'] = true;
I would announce that possibility of changing the name and make it available for a restricted time.

YES! Thank you, goodness! I was finding such solution whole day. It makes a trick for me in theme hook. I slightly modified it to fallback to username if display name was not set:

<?php if (!defined('APPLICATION')) exit;


class ForumThemeHooks implements Gdn_IPlugin {
    public function setup() {
        return true;
    }
}


if (!function_exists('userAnchor'))
{
    function userAnchor($User, $CssClass = null, $Options = NULL)
    {
        static $NameUnique = null;
        if ($NameUnique === null) {
            $NameUnique = c('Garden.Registration.NameUnique');
        }
        if (is_array($CssClass)) {
            $Options = $CssClass;
            $CssClass = null;
        } elseif (is_string($Options)) {
            $Options = array('Px' => $Options);
        }
        $Px = val('Px', $Options, '');
        $DisplayName = GetUserDisplayName($User);
        $Text = val('Text', $Options, htmlspecialchars($DisplayName));
        $Attributes = array(
            'class' => $CssClass,
            'rel' => val('Rel', $Options)
        );
        if (isset($Options['title'])) {
            $Attributes['title'] = $Options['title'];
        }
        $UserUrl = userUrl($User, $Px);
        return '<a href="'.htmlspecialchars(url($UserUrl)).'"'.attribute($Attributes).'>'.$Text.'</a>';
    }


    function GetUserDisplayName($User)
    {
        $DisplayName = $User->Name;
        $SQL = Gdn::sql();
        $SQL
                ->Select('u.Value')
                ->From('UserMeta u')
                ->Where('u.UserID', $User->UserID)
                ->Where('u.Name', "Profile.Fullname");
        
        $UserMeta = $SQL->Get()->FirstRow();
        if (isset($UserMeta->Value) and !empty($UserMeta->Value)) {
            $DisplayName = $UserMeta->Value;
        }
        return $DisplayName;
    }
}

Well, yeah, activity titles are not affected by it as you noted. Seems like a problem with Vanilla+Smarty user modifier (applications/dashboard/views/activity/helper_functions.php, line 30, function Gdn_Format::to), but as expected behavior users mentioned in activity should convert to userAnchor result, but no luck today.
