Notification system


Notification System plugin creates and maintains a notification system for users on WordPress site.

The plugin has the Options page in the site console, with relevant buttons and controls. Please see screenshots.


Notifications are custom posts of type notification. There is a standard custom post interface, with a menu in admin.

Administrator can create, edit, and delete notifications. One taxonomy is available: Channel. Administrator is able to add, edit, and delete taxonomy terms. To restrict notification to some users, add user logins as a comma-separated list.


Plugin creates page /notifications “on the fly” — it does not exist in the database. Information on this page is visible only to the logged-in users (restricted by permissions in REST API Controller).

Plugin creates a popup window if url contains hash #notifications, like that: This is an easy way to show a popup window with notifications from anywhere. Just create a link like <a href="">Notifications</a> and a click on this link will open a popup window with notifications.

Logged-in users can list notifications and filter them by a channel.

Show more button provides pagination of the notification list.

For those users who have the capability ‘edit_posts’, additional buttons are shown: Create, Update, and Delete. Popup windows provide relevant inputs. All notifications can be edited right from the frontend.

Site administrators

Add a custom link to the menu, with #notifications url. Use any navigation label or space(s) for empty label. Save menu. On the site frontend, you will see a new menu item with icon and unread count. By clicking on this menu item, a popup window with notifications will be opened.


Create an element(s) with the class unread-notifications-count. The best place for such element(s) is somewhere in the header or menu. It(they) can be updated by plugin during custom JS event update_unread_counts. Example:

    const count = 5;
        new CustomEvent(
            { 'detail': count }

From php code, count element(s) for current user can be updated using ‘update_unread_counts’ action. Example:

    do_action( 'update_unread_counts' );


The plugin is prepared for translation. All strings are output via gettext functions. There is a .pot file in /language directory with strings collected.


The PHP code conforms to PHP 7.0 level.
The JS code conforms to ES6 level.

All code is checked by php Code Sniffer, and conforms to WordPress Coding Standards.

Automatic installation

Automatic installation is the easiest option as WordPress handles the file transfers itself, and you don’t need to leave your web browser. To do an automatic installation of Notification Systems plugin, log in to your WordPress dashboard, navigate to the Plugins menu and click Add New.

In the search field type “notification system” and click Search Plugins. Once you’ve found our plugin, you can view details about it such as the point release, rating and description. Most importantly, you can install it by simply clicking “Install Now”.

Manual installation

The manual installation method involves downloading our plugin and uploading it to your webserver via your favourite FTP application. The WordPress codex contains instructions on how to do this here.


Automatic updates should work like a charm; as always though, ensure you back up your site just in case.
