Users who configure to block custom post types will notice that you don’t get the meta box that WP-Members shows for blocking (or unblocking) posts and pages. While you can still use custom fields directly for custom post blocking/unblocking at the individual post level, it’s nice to have the meta box. So I’ve put together a code snippet for you to use to implement this on your custom post type editors.
This is a new method of blocking custom post types. There are two main differences over the method described here and the original method.
First, this method is a little more scalable. If you have multiple custom post types and want to set a blocking value for each, you only need to add to the settings array. Second, this method allows you to override the blocking value on an individual custom post type post than you have set for the custom post type as a group. This operates the same as regular posts and pages. It also takes advantage of the new extra settings that WP-Members version 3.0 offers.
With explosion of custom post types in WordPress 3.0, the WordPress world has changed somewhat from what it was when WP-Members was first developed. If you have a theme or site that uses custom post types, you may find that you need to make some adjustments to accommodate what content you would like to be blocked.
