How to change the condition to AND in accessing content by role in a view-block?

Yes, the Role access plugin is written in a way that its access method works effectively like an OR:

public function access(AccountInterface $account) {
  return array_intersect(array_filter($this->options['role']), $account->getRoles());
}

To change this behavior, you can do it in two ways:

• Creating a new ViewsAccess plugin that mostly works like Role but operates with an AND. To do this, extend the Role class, override the access method, and then declare this class as a new @ViewsAccess plugin (remember to give it a unique ID and a new name). This new plugin will show up beside the existing Role plugin.

• Alternatively, you can add an option on the existing Role plugin to make it behave like an AND when told to. To do this, you extend the existing Role class, override buildOptionsForm method to add the option, override the access method to only work like an AND if it's configured to, then alter the existing Role plugin's class to point to your extended version instead of the one from Views.

  • If you're familiar with working with form alters and view alters to modify forms and how things render based on the form values, this approach is almost similar.
