EntityAccessControlHandler::createAccess

public EntityAccessControlHandler::createAccess($entity_bundle = NULL, AccountInterface $account = NULL, array $context = array(), $return_as_object = FALSE)

Checks access to create an entity.

Parameters

string $entity_bundle: (optional) The bundle of the entity. Required if the entity supports bundles, defaults to NULL otherwise.

\Drupal\Core\Session\AccountInterface $account: (optional) The user session for which to check access, or NULL to check access for the current user. Defaults to NULL.

array $context: (optional) An array of key-value pairs to pass additional context when needed.

bool $return_as_object: (optional) Defaults to FALSE.

Return value

bool|\Drupal\Core\Access\AccessResultInterface The access result. Returns a boolean if $return_as_object is FALSE (this is the default) and otherwise an AccessResultInterface object. When a boolean is returned, the result of AccessInterface::isAllowed() is returned, i.e. TRUE means access is explicitly allowed, FALSE means access is either explicitly forbidden or "no opinion".

Defines a default implementation for entity access control handler.

Code

public function createAccess($entity_bundle = NULL, AccountInterface $account = NULL, array $context = array(), $return_as_object = FALSE) {
  $account = $this->prepareUser($account);
  $context += array(
    'entity_type_id' => $this->entityTypeId,
    'langcode' => LanguageInterface::LANGCODE_DEFAULT,
  );

  $cid = $entity_bundle ? 'create:' . $entity_bundle : 'create';
  if (($access = $this->getCache($cid, 'create', $context['langcode'], $account)) !== NULL) {
    // Cache hit, no work necessary.
    return $return_as_object ? $access : $access->isAllowed();
  }

  // Invoke hook_entity_create_access() and hook_ENTITY_TYPE_create_access().
  // Hook results take precedence over overridden implementations of
  // EntityAccessControlHandler::checkCreateAccess(). Entities that have
  // checks that need to be done before the hook is invoked should do so by
  // overriding this method.

  // We grant access to the entity if both of these conditions are met:
  // - No modules say to deny access.
  // - At least one module says to grant access.
  $access = array_merge(
  $this->moduleHandler()->invokeAll('entity_create_access', array($account, $context, $entity_bundle)), 
  $this->moduleHandler()->invokeAll($this->entityTypeId . '_create_access', array($account, $context, $entity_bundle))
  );

  $return = $this->processAccessHookResults($access);

  // Also execute the default access check except when the access result is
  // already forbidden, as in that case, it can not be anything else.
  if (!$return->isForbidden()) {
    $return = $return->orIf($this->checkCreateAccess($account, $context, $entity_bundle));
  }
  $result = $this->setCache($return, $cid, 'create', $context['langcode'], $account);
  return $return_as_object ? $result : $result->isAllowed();
