silverstripe-announce

Announce things to the page controller & view in SilverStripe. Can be used to power plain messages, modals, alerts, and callouts.

Multiple announcements can be stacked.

Announcements can be templated to match component libraries such as Bootstrap.

Installation

Note: For a similar module in SilverStripe 3, consider using axyr/silverstripe-flashmessage

• PHP >= 5.6

Introduction

Create announcements with Titles, Headings, Contents, Footers and Actions. Control whether they should be stored for later responses. Control whether they should be dismissable.

Announcements are retained at StilverStripe's Controller, and stored in the Announcement store (default is $_SESSION).

Each announcement is made available to the view via a SilverStripe Controller extension.

Only one set of announcements can be stacked at a time.

The announcement store can be replaced with a custom class that implements AnnouncementStoreInterface;
