如何通过PHP和MySQL编辑注册用户信息？

我不确定如何问这个问题，但对于大多数更有经验的PHP程序员来说，这听起来很琐碎......因此，我已经成功地设置了一个注册和登录系统，还有一个管理员部分，管理员可以在其中看到所有当前注册的用户。我想要的是管理员能够编辑用户的详细信息，并且还能够删除/阻止他们。其实我已经成功实现了删除功能。如何通过PHP和MySQL编辑注册用户信息？

这这里代码的页面，其中管理员可以看到用户：

如果有人可以告诉我我做错了什么，或者甚至向我解释这样做的更好方法，请让我知道......先谢谢了！

怎么回事？ – sdleihssirhc

首先，我会告诉你我成功地做了什么......我可以点击链接“​​Delete”，并成功地从数据库中删除了一个用户。当我点击“编辑”链接时，我被带到了一个页面，该页面已经填写了表单中的用户详细信息，并且我可以根据需要修改它们（另外，我希望为我的用户单独实施此操作）。当我编辑任何字段时，点击“提交”按钮，我收到一条预先定义的错误消息，说“错误！ID无效。”。如果需要，我可以给你文件。 – Rob

看起来问题出在你隐藏输入的'name'：你正在调用'id'，但是后来寻找'$ _POST ['user_id']'。如果你改变这些以匹配，这是否解决了这个问题？ – sdleihssirhc

首先，它看起来像你用纯文本存储密码。这是一个很大的不不！

对于更新用户信息对MySQL的看看UPDATE命令：http://dev.mysql.com/doc/refman/5.0/en/update.html

对于删除/块的问题，你可以添加存储用户状态（已删除，阻止活跃等），另一列。然后，您可以在用户登录或访问页面时检查此列的状态。

我只是在那里存储个人参考的密码，这是在我的便携式服务器上，但是一旦我上传它就会被更改。 – Rob
