Notification Message

What This Module Does

The Notification Message module allows site administrators to create and broadcast notification messages that appear throughout a Drupal site. Notification messages can be broken into different types to support multiple use cases. Messages can be configured with:

• Time-based publishing – Set start and end dates to control when messages appear
• Conditional display – Show messages based on user roles, page paths, content types, or any custom Drupal condition
• Entity awareness – Notification messages are aware of entities exposed on the route, which integrate with Drupal's Condition API
• Multiple message types – Create different notification categories for different use cases
• Dismissible messages – Let users close notifications, shown only once per browser session via cookie-based storage

Use Cases

• Display site-wide outage or maintenance announcements at a specific date and time
• Show promotional banners during specific time periods
• Target notifications to a subset of users based on role
• Display context-aware messages on specific content types
• Create dismissible alerts that users can close

How It Works

1. Create message types – Define different notification categories with configurable conditions and dismiss settings
2. Create messages – Add notification content with publish dates and optional display conditions
3. Place the block – Add the "Notification Messages" block to any region
4. Conditions evaluate – Messages automatically show/hide based on configured conditions and dates
