Notifications

Have an icon in top menu about notifications to user. Can be bound to user or survey.

Also need an 'irritating' message type that will be 'new' until a certain condition is fulfilled (like survey must be activated).

GUI

• Bell icon
• List of all messages in menu where you can can see which messages are new
• Delete all messages

Usage

All notifications are created on server side with PHP. A page reload is always necessary to see new notifications.

A notification can either be of type 'important' or the default type 'log'. Important messages will show a modal popup at page load. Default messages will only show a notification at the bell in the admin menu.

See examples below for more information.

Database

New database table required to make notifications persist between login/logout.

Fields:

• id
• entity, like survey, user, ...
• entity_id, survey id, user id, ...
• title, title of message (shown in dropdown and overview)
• message, the actual message
• display_class, success, danger, default
• importance, 1 = normal, 3 = high/popup on page load
• status, new, read
• created, datetime
• first_read, datetime

Examples

Create a new notification for a survey

This notification will be visible for all users who visit the survey.

$not = new Notification(array(
  'survey_id' => 316222,
  'title' => 'My title',
  'message' => 'Hello, and welcome to LimeSurvey! Anyone who can see this survey can see this message.'
));
$not->save();

Send an important notification

Visible on page load.

$not = new Notification(array(
  'survey_id' => 316222,
  'title' => 'My title',
  'importance' => Notification::HIGH_IMPORTANCE,
  'message' => 'This notification will be a pop-up modal automaticall opened at load'
));
$not->save();

Notification to a specific user

Only this user can see this notification.

$user = ...
$not = new Notification(array(
  'user_id' => $user->id,
  'title' => 'My title',
  'message' => 'This is a love letter only Marge can see.'
));
$not->save();

Broadcast

All users will get this notification.

Notification::broadcast(array(
  'title' => 'To all users',
  'message' => 'I\'m in love with Marge. I don\'t care if everyone knows.'
));

Broadcast to superadmin

This is how your broadcast a message to all superadmins. Also using localization.

$superadmins = User::model()->getSuperAdmins();
Notification::broadcast(array(
    'title' => gT('Database update'),
    'message' => gT('The database has been updated to version 259. New version includes notification system.')
), $superadmins);

Display class

You can change the modal class of the modal popup using display_class.

$not = new Notification(array(
  'survey_id' => 316222,
  'title' => 'Error',
  'message' => 'This modal will have a red panel header, because it\'s an error.',
  'display_class' => 'warning'
));
$not->save();

Open issues

• Merge with Yii flash system?
• More plugin friendly? E.g. having a message history page, adding soft delete.
