Node revision routes upcast the {node} and {node_revision} parameters

Summary

The node revision routes, like /node/123/revisions/456/view, the code \Drupal::routeMatch()->getParameter('node') and \Drupal::routeMatch()->getParameter('node_revision') now return a Node object. Before Drupal 9.3.0, this code returned an integer when used on the following routes:

• entity.node.revision: /node/{node}/revisions/{node_revision}/view
• node.revision_revert_confirm: /node/{node}/revisions/{node_revision}/revert
• node.revision_revert_translation_confirm: /node/{node}/revisions/{node_revision}/revert/{langcode}
• node.revision_delete_confirm: /node/{node}/revisions/{node_revision}/delete

Now, that code always returns a Node object.

Before

Use

$nid = \Drupal::routeMatch()->getParameter('node');
$node = \Drupal\node\Entity\Node::load($nid);
$vid = \Drupal::routeMatch()->getParameter('node_revision');
$node_revision = node_revision_load($vid);

to get the (integer) node ID $nid and the Node object $node Or to get the (integer) revision ID $vid and the Node revision object $node_revision

After

Use

$node = \Drupal::routeMatch()->getParameter('node');
$nid = $node->id();
$node_revision = \Drupal::routeMatch()->getParameter('node_revision');
$vid = $node_revision->getRevisionId();

To get just the node ID or revision ID, use

$nid = \Drupal::routeMatch()->getRawParameter('node');
$vid = \Drupal::routeMatch()->getRawParameter('node_revision');
