Session Timeout Notification

Session Timeout Notification is a module for Drupal 8, utilizing PHP's session variables. This will provide the users a simple notification of an upcoming session expiration, allowing them to renew their current session without losing any critical data due to unknown loss of session.

Installation

1. Place the timeout-notification directory in your modules directory.
2. Enable the Timeout Notification module at /admin/modules.

Customization

For control of PHP session variables, if not already set through PHP configuration, you will need to configure them through the services.yml file found in sites/default/ . If this file does not exist, create it from the default.services.yml .

Inside your services.yml file, find the gc_maxlifetime setting. By default gc_maxlifetime is set to 200000 seconds. Alter this to match your desired session lifetime.

gc_maxlifetime - is used to set the session lifetime (in seconds). i.e. the time from the user's last visit to the active session may be deleted by the session garbage collector. When a session is deleted, authenticated users are logged out,and the contents of the user's $_SESSION variable is discarded.

Configuration

Settings can be altered at /admin/config/timeout_notification for project specific customization.

i.e. seconds in advance to notify users of upcoming session expiration. By default, this is set to 60 seconds
