Bug ID: 62029
Summary: Saving preferences with returning "false" from
allowRealNameChange() in AuthPlugin.php causing
"Undefined index: realname"
Product: MediaWiki
Version: 1.22.2
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Unprioritized
Component: User preferences
Assignee: [email protected]

If a sysop doesn't want a user can change his realname (because its set by
extend authPlugin) and adds a allowRealNameChange(), which returns false, to
the AuthPlugin.php, you get a php notice "Undefined index: realname in
Preferences.php line 1439".
If allowPropChange() or allowRealNameChange() from AuthPlugin.php return false
then there is a missing key 'realname' in $formData.
This causes the mentioned warning and an empty realname string for the user.
This should either be checked before saving or the index should include the old
realname by default.
Workaround for me: Edit Preferences.php like this:
Preferences.php line 1436
// Fortunately, the realname field is MUCH simpler
// (not really "private", but still shouldn't be edited without permission)
if ( !in_array( 'realname', $wgHiddenPrefs ) && $user->isAllowed(
'editmyprivateinfo' ) ) {
if (!array_key_exists('realname', $formData)) {
$formData['realname'] = $user->getRealname();
}
$realName = $formData['realname'];
$user->setRealName( $realName );
}
Message in error.log:
PHP Notice: Undefined index: realname in
/srv/web/wiki.xxxxxx.org/public/mediawiki-1.22.2/includes/Preferences.php on
line 1439, referer: http://wiki.xxxxxx.org/wiki/Spezial:Einstellungen
