Indicates whether the block should be shown.

Blocks with specific access checking should override this method rather than access(), in order to avoid repeating the handling of the $return_as_object argument.

Parameters

\Drupal\Core\Session\AccountInterface $account: The user session for which to check access.

Return value

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

Overrides BlockPluginTrait::blockAccess

  if (!$entity instanceof FieldableEntityInterface || !$entity->hasField($this->fieldName)) {
    return $access->andIf(AccessResult::forbidden());
  }
  // Check field access.
  $field = $entity->get($this->fieldName);
