Unsaved changes indicator#

The CMS shows a small inline indicator on edit forms after a user has started editing the form (contains unsaved changes) after a configurable period of time. The indicator starts as a subtle "notice" and escalates to a more prominent "warning" after a second period. This helps editors remember to save their work and reduces accidental data loss.

The indicator activates only when the form has started editing the form. When the form then changes to a state where there are no unsaved changes, either by saving or reverting the unsaved changes, then its timer resets. By default, a notice appears after 5 minutes, escalating to a warning after 10 minutes. Notice and warning are independent levels; you can disable either or both through configuration.

Configuration#

You can configure the indicator using YAML. The configuration controls the intervals in minutes for the two levels. Set either level to 0 to disable that level. Set both to 0 to disable the indicator entirely.

Example: change the notice to 10 minutes and the warning to 20 minutes

yaml

SilverStripe\Admin\Forms\UnsavedChangesIndicator:
  minutes:
    notice: 10
    warning: 20

To disable the warning level only:

yaml

SilverStripe\Admin\Forms\UnsavedChangesIndicator:
  minutes:
    warning: 0

To disable the indicator entirely:

yaml

SilverStripe\Admin\Forms\UnsavedChangesIndicator:
  minutes:
    notice: 0
    warning: 0
