如何对未登录的用户隐藏php功能
如何对未登录的用户隐藏php功能
提问于 2016-05-22 19:45:31
我正在创建一个网站，我遇到了一个问题，在搜索了一段时间后，我发现很难在网上找到解决方案。
所以我的网站是使用bootstrap框架制作的，有许多页面可以显示数据库中的记录，然后编辑或删除，并将新记录添加到数据库中。现在我显然不想让任何人来我的网站上删除或编辑我的任何记录，这就是为什么我创建了一个登录和注册系统，它工作得很好。
但问题是，在用户登录之前，我如何对用户隐藏添加、编辑和删除按钮？或者我必须创建另一个页面来显示数据？
例如，我的新闻页面包含以下文件: config.php；index.php；add_news.php；edit_news；delete_news.php；read_more.php。现在我想对未登录的用户隐藏add_news.php、edit_news.php和delete_news.php。我真的卡住了，请帮帮忙。
