More Information

This action is called whenever a value for a custom column should be output for a custom post type. Combined with the manage_${post_type}_posts_columns filter, this allows you to add or remove (unset) custom columns to a list of custom post types.

For built-in post types and multiple custom types, use manage_posts_custom_column.
