Description
This is an example illustrating how to restrict access to nodes based on some criterion associated with the user.
Database definition:
<?php
DELETE FROM node_access;
INSERT INTO node_access (nid, gid, realm, grant_view, grant_update,
grant_delete) VALUES (0, 1, 'example', 1, 0, 0)
?>
This SQL needs to be run before the module will work properly. The installer system will probably perform this work in the future. The first line removes any existing grants, including (most importantly) the universal grant installed by default that gives read access to every node for everyone. The second line grants read access to every node for users with the "access private content" permission; in the scheme we're defining here, each node will either be private (in which case it can always be read by anyone with that permission) or public (in which case it can be read by everyone). We'll take care of public nodes in node_access_example_nodeapi().
