只是为了装箱，我提供了完整的代码。问题是，它自己的 PAGINATION 工作正常......并且 ORDER 功能也可以单独正常工作。但他们不想一起工作。结果我有工作分页，如果尝试使用排序它只是变成空页。

我需要的是……以某种方式使排序方法与分页一起工作，但我不知道该怎么做。

当我使用分页时，我有这个网址：

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

当我使用订单时，还有这个：

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

并且我需要这样的 URL：

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...它会记住用户如何对列表进行排序并且打开页面 (pn=1, pn=2) 会发生变化。

可能是一些如何保存排序结果然后在分页中使用它..可能需要在按下提交按钮时保存它？但是如何保存用户的结果？？？

【问题讨论】：

到底是什么问题？你没有得到结果，错误 sql，什么？！
问题是......分页工作正常，但是当我使用 ORDER 列表时它不起作用......但是如果我删除分页，订单列表正在工作......
如果您执行 var_Dump($queryMainList) 并将结果粘贴到 mysql 管理面板中？这给了你什么？
string(470) "选择 newsvid.id，newsvid.addName，newsvid.vidTitle，newsvid.vidType，newsvid.size，newsvid.url，newsvid.vidSD，newsvid.published，videoinformation.vidLD， videoinformation.vidYear, videoinformation.vidCity, videoinformation.vidZanr, videoinformation.vidZanr2, videoinformation.vidZanr3, videoinformation.vidQuality, videoinformation.vidTranslated, videoinformation.vidTime FROM newsvid, videoinformation WHERE newsvid.id = videoinformation.id AND approved='1'LIMIT 0,2"
在你的数据库中运行那个 SQL.. 看看会返回什么.. (prob error)
