注册自定义帖子类型时，请显式设置功能类型；

register_post_type( \'my_type\',  array(
    \'capability_type\' => \'my_type\',
    // other args
) );

现在，默认情况下，只有超级管理员才能添加/编辑/删除它们，直到您授予其他角色相关的功能（例如，正如@tnorthcutt所建议的，使用Members Plugin).

[edit_post] => edit_my_type
[read_post] => read_my_type
[delete_post] => delete_my_type
[edit_posts] => edit_my_type
[edit_others_posts] => edit_others_my_type
[publish_posts] => publish_my_type
[read_private_posts] => read_private_my_type
