Quickly Protecting a Few Nodes from Deletion in Drupal 8
I’m working on a Drupal 8 site with some critical pages for which we do not want to allow deletion. The homepage, for example, is a basic page; we do not want to allow anyone (even UID #1) to delete this page. If there comes a time where UID #1 decides they need to, they’ll have to update this simple code to support that. We need not make it any more complicated than that for this particular project.
Here’s a solution that:
- shows nothing but an error on the “Delete” form for specific nodes (works for all users)
- prevents deletion by any means (works for all users except UID #1)
- why except UID #1? because hook_node_access doesn’t run for this user
