让密码错误的信息显示在网页中,就像百度提示的这样。用php判断密码错误后,怎么在html中显示

提供一个简单的思路,Ajax提交数据,根据后台返回的状态码判断是否显示错误信息。

如果密码错误就在控制器中,即MVC中的V,设置$message='用户名或密码错误';

视图判断

<code>if(!empty($message)){
echo $message;
}
</code>
Copy after login

将错误加入session。出错到哪个页面在那个页面显示后设定为null。
也可以AJAX去做。
具体怎么做看你代码究竟是怎么样的才能决定。

就是楼上说的,返回错误码,前端有一个对应的错误码json,通过code值找到对应的错误信息,然后显示在界面上就行了。
