我如何控制落后&在Php中转发按钮浏览器？ [英] How Can I Control On Backward & Forward Buttons Browser In Php?

问题描述

如何控制php中的后退和前进按钮浏览器？



i想要了解用户是否登录并在浏览器后面点击后退



它不回来了！

解决方案

PHP在服务器端运行，而不是在浏览器（客户端）中运行。你可以使用JavaScript ...

http://www.w3schools.com/ jsref / obj_history.asp [ ^ ]

您不直接控制这些按钮的状态 - 它们是浏览器控件的一部分，而不是Web应用程序。问题与PHP（服务器端）无关。您可以通过控制本地Web缓存来实现这些按钮： http://en.wikipedia.org/wiki/Web_cache [ ^ ]。



坦率地说，一遍又一遍地回答这些问题并不好。您会在许多CodeProject答案中找到代码示例（当然是Javascript）：

如何在注销后使用后退按钮 [ ^ ]，

退出问题 [ ^ ]，

在注销后处理浏览器后退按钮 [ ^ ]，

注销后asp.net mvc中的浏览器缓存问题 [ ^ ]。



更好的是，找到在过去的CodeProject答案中可以帮助您的答案： http：// www.codeproject.com/search.aspx?q=browser+back+button+cache&doctypeid=5 [ ^ ]。

解决方案

PHP runs at server side, not in the browser (which is client). You can use however JavaScript for that...
http://www.w3schools.com/jsref/obj_history.asp[^]

You don't control states of these buttons directly — they a part of browser controls, not your Web application. And the problem is not related to PHP (server side). You can effect these buttons by controlling your local Web cache: http://en.wikipedia.org/wiki/Web_cache[^].

Frankly, it would not be good to answer over and over the to questions which were asked so many times. You will find the code samples (Javascript, of course), in many CodeProject answers:
how to use back button after logout[^],
Logout problem[^],
Handling browser back button after logout[^],
browser cache problem in asp.net mvc after logout[^].

Better yet, find the answer which can help you the most in past CodeProject answers: http://www.codeproject.com/search.aspx?q=browser+back+button+cache&doctypeid=5[^].
