Previously we talked about how to set the Field Permissions on role level.
Drupal 7 – Set field permission by role using Field Permissions
As i have mentioned, it does not work for the default node title field. One solution is to hide the node title field and set it automatically. This could be achieved by the Automatic Nodetitles.
1. Install the module.
2. Edit the content type and you could find the Automatic title generation settings.
3. With the help of the Token module, we could hide the default node title field and auto fill in any manual made CCK field which could be controlled by the Field Permissions module.
Done =)
