Introduction

Giving feedback to a user is an important part of a good application. Flash messages provide notifications to the user, such as for successful form submissions, failure to save data in the database, and incorrect authentication credentials. A message is created at the end of one request, and shown to the user in the next request. Flash messages are self-expiring and session-based.

To create and expose flash messages in a laminas-mvc-based application, this packages provides:

• a controller plugin to create and retrieve messages
• a view helper to render the messages

A flash message is set in a controller and then rendered in a view script.

Namespaces

The controller plugin and the view helper support different types of messages:

• default
• info
• success
• warning
• error

These namespaces provide support for handling different output formats.
