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>

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。

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
