I know how to get the user who created a node after getting the node object.

$node = \Drupal::routeMatch()->getParameter('node');
$uid = $node->getOwnerId();
$user = \Drupal\user\Entity\User::load($uid);

Since an alternative to retrieving values of the node object is for example $node->nid->value, I tried to get the revision user ID this way.

$ruid = $node->revision_uid->value;

Unfortunately, this doesn't work, although I see with the Devel module that there is a value. So what is the equivalent in Drupal 8 to $node->revision_uid in Drupal 7?

$node->getOwnerID() returns the user ID for the user who created the node. If you need the user who created the revision, you need to use $node->getRevisionUser(), or $node->getRevisionUserId() for the user ID.

  • Great, thanks. So I suppose I will try the "set…" and "get…" found in node class member names on this page the next time: api.drupal.org/api/drupal/… – upunkt Mar 31 '18 at 21:34

    That page lists all the methods available for the Node class, including the ones defined in a parent class, or a trait used by the class. So, yes, that is the first place to look. It's not always that quick to find the right method to use, but it's a start. – kiamlaluno♦ Apr 1 '18 at 1:19
