PHP样式有问题吗

所以基本上，我想做的是允许用户更改他们的详细信息，这大部分是有效的，所以让我们开始着手解决这个问题。如果用户更改了密码，并且验证成功，则会更改密码，并显示一条消息“密码已更改”。所以这是我的问题，如果我故意更改或犯错误，它会在所有验证上显示“主页按钮”。因此，假设用户更改了密码“密码已更改”，下面有一个“主页”按钮，也可以说电子邮件更改失败了“您的电子邮件未更改”，还有一个“主页”按钮。因此，我试图做的基本上是为所有字段设置一个home按钮，而不必执行

（我需要在这个页面上设置一个按钮，以便每次验证都使用）

（如果我在这里输入“home”并更改当前电子邮件和密码，它将重复“home”两次）

我仍在检查，但问题可能出在您在php代码中回显的标记中使用的CSS类中。看看吧
