Everyone saw a nice drop-down list with all notifications you have at the top-right corner of every page. Let’s look, how to add our own notifications to this list. It is very easy!
1. Create a GLOBAL phrase, that will be displayed as a text for your notification. Let’s consider it’s name to be MyNotificationName.
2. Create plugin for hook notifications_list with the following code:
if($MyNotificationNeedsToBeShown) {
$notifications['MyNotificationName'] = array(
'phrase' => $vbphrase['MyNotificationName'],
'link' => 'mylinkpage.php',
'order' => 100
);
$vbulletin->userinfo['MyNotificationName'] = $MyNotificationCount;
}
- MyNotificationName - is just a string, a unique name of your notification.
- $MyNotificationNeedsToBeShown – you can insert here any condition, that evaluates to true, then your notification needs to be shown
- mylinkpage.php – is the name of the page, user will be redirected to, when he clicks your notification in menu. Page name should be relative to VB root or absolute (http://…)
- $MyNotificationCount – a number, that will be shown near your notification. This number will be added to a total notifications number displayed by VB.
That’s all 
Really simple, eh?
