function node_type_example_install in Examples for Developers 3.x

Same name and namespace in other branches
  1. 8 node_type_example/node_type_example.install \node_type_example_install()

Implements hook_install().

We don't want users to be able to delete our locked_content_type content type. So therefore we have to tell Drupal that this is the case. This can't be done in the content type's configuration YAML file, so we have to do it in code, here.

  Drupal::state()
    ->set('node.type.locked', $locked);
