Drupal GoAway content: Ban/block Authors

Posted Wed, 12/10/2011 - 11:06am by beautifulmind

This CodeLet allows you to add a 'ban IP/block user' link for content using GoAway module. GoAway module just supports banning user IPs in comment and it doesn't offer a feature to ban/block author's IP/user. The CodeLet takes care of the link text display depending on the data it finds from the db. If user's IP is available, it will display 'Ban IP', otherwise it will display 'Block user'. You can 'Unban/Unblock' an author in similar way.
This CodeLet requires Drupal's Goaway module -- http://drupal.org/project/goaway installed and configured.
