仅仅为了包装，我提供了完整的代码。问题是， PAGINATION 对它自己的工作正常......并且 ORDER 功能也可单独运行。但他们一起不想工作。结果我有工作分页，如果尝试使用排序它只是成为空页。

我需要什么..以某种方式使排序方法与分页一起工作，但我坚持如何做到这一点。

当我使用分页时，我有这个URL：

http://example.net/view.php?pn=3

当我使用订单时这个：

http://example.net/view.php?order=NEW&vType=Film&vGenre=AnyGenre1&vGenre2=AnyGenre2&vGenre3=AnyGenre3&vYear=AnyYear&vCity=AnyCity

AND 我需要的网址如下：

http://example.net/view.php?pn=3&order=NEW&vType=Film&vGenre=AnyGenre1&vGenre2=AnyGenre2&vGenre3=AnyGenre3&vYear=AnyYear&vCity=AnyCity

如果您对页面进行排序...它将记住用户对列表进行排序的方式，并且打开页面（pn = 1，pn = 2）将会更改。

可能是一些如何保存排序结果，然后在分页中使用它...需要保存它可能是按下提交按钮？但是如何保存用户???
