Chris@0: /**
Chris@0:  * Inform the node access system what permissions the user has.
Chris@0:  *
Chris@0:  * This hook is for implementation by node access modules. In this hook,
Chris@0:  * the module grants a user different "grant IDs" within one or more
Chris@0:  * "realms". In hook_node_access_records(), the realms and grant IDs are
Chris@0:  * associated with permission to view, edit, and delete individual nodes.
Chris@0:  *
Chris@0:  * The realms and grant IDs can be arbitrarily defined by your node access
Chris@0:  * module; it is common to use role IDs as grant IDs, but that is not required.
Chris@0:  * Your module could instead maintain its own list of users, where each list has
Chris@0:  * an ID. In that case, the return value of this hook would be an array of the
Chris@0:  * list IDs that this user is a member of.
Chris@0:  *
Chris@0:  * A node access module may implement as many realms as necessary to properly
Chris@0:  * define the access privileges for the nodes. Note that the system makes no
Chris@0:  * distinction between published and unpublished nodes. It is the module's
Chris@0:  * responsibility to provide appropriate realms to limit access to unpublished
Chris@0:  * content.
Chris@0:  *
Chris@0:  * Node access records are stored in the {node_access} table and define which
Chris@0:  * grants are required to access a node. There is a special case for the view
Chris@0:  * operation -- a record with node ID 0 corresponds to a "view all" grant for
Chris@0:  * the realm and grant ID of that record. If there are no node access modules
Chris@0:  * enabled, the core node module adds a node ID 0 record for realm 'all'. Node
Chris@0:  * access modules can also grant "view all" permission on their custom realms;
Chris@0:  * for example, a module could create a record in {node_access} with:
Chris@0:  * @code
Chris@0:  * $record = array(
Chris@0:  *   'nid' => 0,
Chris@0:  *   'gid' => 888,
Chris@0:  *   'realm' => 'example_realm',
Chris@0:  *   'grant_view' => 1,
Chris@0:  *   'grant_update' => 0,
Chris@0:  *   'grant_delete' => 0,
Chris@0:  * );
Chris@18:  * \Drupal::database()->insert('node_access')->fields($record)->execute();
Chris@0:  * @endcode
Chris@0:  * And then in its hook_node_grants() implementation, it would need to return:
Chris@0:  * @code
Chris@0:  * if ($op == 'view') {
Chris@0:  *   $grants['example_realm'] = array(888);
Chris@0:  * }
Chris@0:  * @endcode
Chris@0:  * If you decide to do this, be aware that the node_access_rebuild() function
Chris@0:  * will erase any node ID 0 entry when it is called, so you will need to make
Chris@0:  * sure to restore your {node_access} record after node_access_rebuild() is
Chris@0:  * called.
Chris@0:  *
Chris@0:  * For a detailed example, see node_access_example.module.

Chris@0:  * node.
Chris@0:  *
Chris@0:  * Node access grants apply regardless of the published or unpublished status
Chris@0:  * of the node. Implementations must make sure not to grant access to
Chris@0:  * unpublished nodes if they don't want to change the standard access control
Chris@0:  * behavior. Your module may need to create a separate access realm to handle
Chris@0:  * access to unpublished nodes.
Chris@0:  *
Chris@0:  * Note that the grant values in the return value from your hook must be
Chris@0:  * integers and not boolean TRUE and FALSE.
Chris@0:  *
Chris@0:  * Each permissions item in the array is an array with the following elements:
Chris@0:  * - 'realm': The name of a realm that the module has defined in
Chris@0:  *   hook_node_grants().
Chris@0:  * - 'gid': A 'grant ID' from hook_node_grants().
Chris@0:  * - 'grant_view': If set to 1 a user that has been identified as a member
Chris@0:  *   of this gid within this realm can view this node. This should usually be
Chris@0:  *   set to $node->isPublished(). Failure to do so may expose unpublished content
Chris@0:  *   to some users.
Chris@0:  * - 'grant_update': If set to 1 a user that has been identified as a member
Chris@0:  *   of this gid within this realm can edit this node.
Chris@0:  * - 'grant_delete': If set to 1 a user that has been identified as a member
Chris@0:  *   of this gid within this realm can delete this node.
Chris@0:  * - langcode: (optional) The language code of a specific translation of the
Chris@0:  *   node, if any. Modules may add this key to grant different access to
Chris@0:  *   different translations of a node, such that (e.g.) a particular group is
Chris@0:  *   granted access to edit the Catalan version of the node, but not the
Chris@0:  *   Hungarian version. If no value is provided, the langcode is set
Chris@0:  *   automatically from the $node parameter and the node's original language (if
Chris@0:  *   specified) is used as a fallback. Only specify multiple grant records with
Chris@0:  *   different languages for a node if the site has those languages configured.
Chris@0:  *
Chris@0:  * A "deny all" grant may be used to deny all access to a particular node or
Chris@0:  * node translation:
Chris@0:  * @code
Chris@0:  * $grants[] = array(
Chris@0:  *   'realm' => 'all',
Chris@0:  *   'gid' => 0,

Chris@0:  * Note that another module node access module could override this by granting
Chris@0:  * access to one or more nodes, since grants are additive. To enforce that
Chris@0:  * access is denied in a particular case, use hook_node_access_records_alter().
Chris@0:  * Also note that a deny all is not written to the database; denies are
