Enforce Revision Logs allows an administrator to force users to write a
revision log message whenever a revision is created. It can also force a
revision to be created for every modification.

If you have several editors for your website's content, it's probable you'll
want to be able to easily track the modifications made by each one on the pages.

When enabling node revisions, you can have access to every previous version of
a node. But having to dig into former revisions to know what has been done, or
to revert to a given point in the past, is not that practical.

Enter log messages. Each time someone updates a node where revisions are
enabled, one can leave a comment on what has been done. The problem with log
messages is that there is no way to make them mandatory, and you'll soon notice
that users often forget or disregard what is only optional.

This module brings a solution by allowing administrators to make revision log
messages required as well as enforcing revisions for every modification.

There are permissions to skip creating a log message and to override the
setting to create a new revision. However, you can also go the other way and
remove the permissions entirely, including from User 1, which could be
important to prevent untracked changes or inadvertent data loss that even
administrators can cause.

Differences from Drupal 7

  • Allow to force revisions for each modification.
  • Allow to force revision log and force revisions for User 1 if permission is
    disabled for the admin role. This helps you with self discipline in creating
  • Settings is under Configuration > Content Authoring (admin/config/content/enforce-revlog)
    rather than Configuration > User Interface (admin/config/user-interface/enforce_revlog).
  • The link to the permissions on the settings page uses either the core
    permission search or the Filter Permissions
    module to go directly to the settings.
  • Wording and user interface improvements including changing the name to
    "Enforce Revision Logs" although the system name remains enforce_revlog


  • Install this module using the official Backdrop CMS instructions at
  • Navigate to Admin > Configuration > Content authoring > Enforce Revision Logs
    (admin/config/content/enforce-revlog) to set the Global settings
    and enable for each content type.
  • Alternatively you can (de)activate Enforce Revision Logs for a given content
    type on the content type configuration form.
  • Configure permissions to override create new revision and skip revision log


Enforce Revision Logs will only be enabled for a node when a revision is about
to be created. Therefore it WON'T require users to enter a log message

  • The node is being created (no previous version exists).
  • "Create new revision" is disabled (on the node form or set as a
    default through the content type configuration form).

Make sure that "Create new revision" is checked as the default behavior
for the content types on which Enforce Revision Log is set.

Ensure the Global settings and permissions are configured to meet your needs.

If the "Create new revision" checkbox on the node editing form is unchecked
while editing a node, Enforce Revision Logs will be disabled. If it's checked
again, Enforce Revision Logs will be enabled again.


On the node add/edit form, Enforce Revision Logs will check if the property
$node->enforce_revlog is set before enabling itself. Therefore you can
define your very own conditions to set/unset $node->enforce_revlog in a
custom module.
