pre\\u get\\u posts正确。

来自的代码将阻止任何非管理员查看其他人的帖子。

要将其限制为仅1个帖子类型，您需要再添加一个条件并选中$typenow==“your\\u custom\\u post\\u type”：

add_action(\'pre_get_posts\', \'filter_posts_list\');
function filter_posts_list($query)
{
    //$pagenow holds the name of the current page being viewed
     global $pagenow, $typenow;  

    //$current_user uses the get_currentuserinfo() method to get the currently logged in user\'s data
     global $current_user;
     get_currentuserinfo();

        //Shouldn\'t happen for the admin, but for any role with the edit_posts capability and only on the posts list page, that is edit.php
        if(!current_user_can(\'administrator\') && current_user_can(\'edit_posts\') && (\'edit.php\' == $pagenow) &&  $typenow == \'your_custom_post_type\')
     { 
        //global $query\'s set() method for setting the author as the current user\'s id
        $query->set(\'author\', $current_user->ID);
        }
}
