public function EntityAccessCheck::access in Drupal 8

Same name and namespace in other branches

1. 9 core/lib/Drupal/Core/Entity/EntityAccessCheck.php \Drupal\Core\Entity\EntityAccessCheck::access()

Checks access to the entity operation on the given route.

The route's '_entity_access' requirement must follow the pattern 'entity_stub_name.operation', where available operations are: 'view', 'update', 'create', and 'delete'.

For example, this route configuration invokes a permissions check for 'update' access to entities of type 'node':

pattern: '/foo/{node}/bar'
requirements:
  _entity_access: 'node.update'

And this will check 'delete' access to a dynamic entity type:

example.route:
  path: foo/{entity_type}/{example}
  requirements:
    _entity_access: example.delete
  options:
    parameters:
      example:
        type: entity:{entity_type}

The route match parameter corresponding to the stub name is checked to see if it is entity-like i.e. implements EntityInterface.

Parameters

\Symfony\Component\Routing\Route $route: The route to check against.

\Drupal\Core\Routing\RouteMatchInterface $route_match: The parametrized route

\Drupal\Core\Session\AccountInterface $account: The currently logged in account.

Return value

\Drupal\Core\Access\AccessResultInterface The access result.

  list($entity_type, $operation) = explode('.', $requirement);

  // If $entity_type parameter is a valid entity, call its own access check.
  $parameters = $route_match
    ->getParameters();
  if ($parameters
    ->has($entity_type)) {
    $entity = $parameters
