Record Level Security

List of other Howto's

Sometimes you want to allow your users to edit certain records but not others from the same node.

To do so, you should override the allowed() action in your node. You may optionally also use setFilter() to hide the records users may not edit.

Notice that just using setFilter will hide the records, but not provide security in case a user hand-crafts a URL to edit a record. In order to provide security you MUST code the allowed() function.

Per-record action security

The following code allows a user to edit only the records that belong to them:

function allowed($action, $record="") 
{ 
    $user = getUser(); 
    if($action=="edit" && $record['owner']['id'] <> $user['id']) 
    { 
        return false; // not allowed if not your own record 
    } 
    // call base class method to perform default authorization in all 
    // other cases. 
    return parent::allowed($action, $record); 
}
