hook_node_grants
- Versions
- 4.6 – 4.7
hook_node_grants($user, $op)- 5 – 7
hook_node_grants($account, $op)
Grant access to nodes.
This hook is for implementation by node access modules. In addition to managing entries in the node_access table in the database, such modules must implement this hook to inform Drupal which "grants" the current user has. For example, in a role-based access scheme, this function would return a list of the roles the user belongs to.
For a detailed example, see node_access_example.module.
Parameters
$user The user object whose grants are requested.
$op The node operation to be performed, such as "view", "update", or "delete".
Return value
An array whose keys are "realms" of grants such as "user" or "role", and whose values are linear lists of grant IDs.
