Translate the New User Email Notification extension if it is available at translatewiki.net

The New User Email Notification extension sends a customisable email to specified recipients when a new user account is created. The extension can send to multiple users, and additional email addresses, and is useful for keeping track of account creation on a small wiki.


To users running MediaWiki 1.35 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension(). If you need to install this extension on these earlier versions (MediaWiki 1.35 and earlier), instead of wfLoadExtension( 'NewUserNotif' );, you need to use:

require_once "$IP/extensions/NewUserNotif/NewUserNotif.php";


The behaviour of the extension, including notification recipients, is managed using the configuration variables below:

Array containing the usernames or identifiers of those who should receive a notification email; defaults to the first user (usually the wiki's primary administrator)
Array containing email addresses to which a notification should also be sent
  • $wgNewUserNotifSender
Email address of the sender of the email; defaults to the value of $wgPasswordSender

For example, you could add this to the "LocalSettings.php" file:

$wgNewUserNotifEmailTargets = [


The subject and text of the notification email sent to each recipient can be customised using two messages:


Subject line

Parameter Value
$1 Site name

Body text

Parameter Value
$1 Username of the recipient
$2 Username of the new account
$3 Site name
$4 Date/time of account creation
$5 Date of account creation
$6 Time of account creation

Further Customisation

You can fully customize both the subject line and the message body, including adding new parameters which can be passed into both of those generators starting in version 1.5.2.

Starting in 1.5.2, you can also extend the message customisation by using hooks added to the extension which allow you to create new subject and body text without hacking the extension code.

This involves creating an extension to the NewUserNotif extension. For this example, the extension file "ExtendedParamsExample.php" can be found in the extension distribution. It is recommended you create a copy of this file and rename it to something meaningful to your site(s).

You would then include the new extension in your localsettings.php after you included the NewUserNotif.php.

. . .
wfLoadExtension( 'NewUserNotif' );
require_once "$IP/extensions/NewUserNotif/[yourExtendeParamsExample].php";
. . .

This available hooks are:

Function Version Hook Description
New User Email Notification 1.5.2 NewUserNotifBody Create text for message body of notification email
1.5.2 NewUserNotifSubject Create text for the subject line of the new user notification email

An example extension that uses this is included in the distribution as "ExtendedParamsExample.php". For more details, see this Customisation example.
