HomeBackend DevelopmentPHP Tutorial当我留言结束后,点击一个alert返回前一页

$data['univ_name']=$id;
$data['user_name']=$user_name;
$data['user_comment']=$_POST['user_comment'];
$data['user_comment_good']=$score;
$data['user_comment_money']=$_POST['user_comment_money'];
$data['user_comment_date']=$_POST['user_comment_date'];
$User->add($data);
$result = $User->select ();
$this->success("留言成功");
}
$this->user_state = $user_state;
$this->display();
这是一段留言代码,当我成功时候 $this->success("留言成功"); 它会跳出来一个页面,这个页面不好看,
现在我想跳出一个alert 或者跳转页面也行,但是当我点击alert的确定按钮时候我希望它能够返回到我写留言的那页
准确说就是我想获取success的URL 让我的alert也能实现回去前一页的效果  请问要怎么做好? 最好有个代码什么的 如果大家说的我不明白 我还能研究一下代码。。


回复讨论(解决方案)

获取refer就可以了。 代码没有

我记得JS可以直接返回上一级的URL的go.history(-1)我记得是这个。

$this->success("留言成功");
改?

echo '<script type="text/javascript">'."\r\n";echo 'alert("留言成功");'."\r\n";echo 'window.history.go(-1);'."\r\n";echo '</script>';

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.
