9.4. Creating pages for a premium account.

In this lesson, we will expand the capabilities of our module and create content that will be available only to registered users or users with a specific role.

Code examples can be viewed on github:

Let's start by adding a new YML file right in our drupalbook.permissions.yml module folder:

access premium pages:
  title: 'Access Premium pages'
  description: 'A custom permission for your pages.'
  restrict access: TRUE

Now go to the access rights page and set access to Premium content for the necessary roles, I will do this for registered users:

/admin/people/permissions

Now in drupalbook.routing.yml create a new route, in which we indicate our new rights and a new method for displaying content:

drupalbook.private_content:
   path: '/private-page'
   defaults:
     _controller: '\Drupal\drupalbook\Controller\FirstPageController::privateContent'
     _title: 'Private content'
   requirements:
     _permission: 'access premium pages'

After adding a new route, you need to clear the cache.

We will also need to add the privateContent () method to our FirstPageController class:

/**
 * Returns a private page.
 *
 * @return array
 *   A simple renderable array.
 */
public function privateContent() {
  $element = array(
    '#markup' => 'Private content',
  );
  return $element;
}

Now you can clear the cache and verify that our page is not accessible to unregistered users.
