Is it possible to get node permissions through PHP. Like I load node id by ID and test it thru user ID. Is this user has permission to view this node or not.

I'm using nodeaccess module and I want to archive this through grants (assigning some users have rights to see and some not depending content). Calling something like if node page is ID = 12 (to get all project certain page). Then if it is I load some project nodes there (created new content type). I have to be sure, that viewer (account) has permission to see this data.

I am not sure if I fully understand your question but this is what I make out of it: you want to check if a certain user has access to a certain node, am I right?

If this is the case, this can easily be achieved with the following code:

// Use this if you want to load the current user.
global $user;
// Use this if you want to load a user by UID.
$user = user_load($uid);
// Load the node object.
$node = node_load($nid);
// Perform the access check.
if (node_access('view', $node, $user)) {
  // The user has permission.
}

You can read more about node_access in the Drupal docs.

  • Thank you for your answer! I tried something similar, but it does not work like I expect.<br/> Code: // Use this if you want to load a user by UID. $user = user_load(16); // Load the node object. $node = node_load(12); // Perform the access check. if (node_access('view', $node, $user)) { echo "test"; } User with ID 12 does not have node (ID 16) view access. It is set by using grants tab. And view is unchecked. But it will still print out "test". – Tõnis Nov 23 '15 at 16:37

I found out real problem. Patrick Scheffer answer is correct but if content is created before installing nodeaccess it does not work. All new content works like expected.

  • Nice! Not sure if this works, but you can also rebuild the permissions to update old content. This can be done via admin/reports/status/rebuild or navigate to Reports -> Status report and the link is under the Node Access Permissions row. – Patrick Scheffer Nov 24 '15 at 8:52
  • Sadly no to be honest. I rebuilt those multiple times. – Tõnis Nov 24 '15 at 20:31
