如何重写这些URL为国家，州，城市？ [英] How to rewrite these urls for country, state, city?

问题描述

我在这里的文章被来自世界各地提交，我记录下来的位置，如国家网站 - ＆GT;状态 - ＆GT;城市，对于像我正在生成URL：

I have a site where articles being submitted from worldwide and I record the location of them as Country -> State -> City, for that I am generating URLs like:

site/location/countryname/statename/cityname

我可以采取要求来照顾，并在查询字符串值，得到一个单一的PHP文件，现在的问题是怎么写的mod_rewrite所以它可以有URL像上面？

I have a single php file which can take care of coming request and gets values in query string, now the problem is how to write mod_rewrite so it can have URL like above?

PS：如果有人删除或Statename的这COUNTRYNAME不应该传递空值，意味着URL可以是：

PS: It should not pass empty values if someone deletes the statename or countryname, means URL can be:

site/location/countryname
site/location/countryname/statename
site/location/countryname/statename/cityname

但不能是：

site/location//statename/cityname
site/location/countryname//cityname

在上面的网址，如果COUNTRYNAME被删除，那么Statename的不应该被视为COUNTRYNAME。读文件名为 location.php

In above urls if countryname is deleted then statename shouldnt be treated as countryname. Reading file name is location.php

谢谢，

推荐答案

好吧我有一个办法做到这一点：

Ok I have got a way to do that:

RewriteRule ^bylocation/([-a-z_]+)(?:/([-a-z_]+)(?:/([-a-z_]+))?)?/?$ location.php?country=$1&state=$2&city=$3 [NC,L,QSA]

这单一规则可以照顾，而不是三个规则。

This single rule can take care, instead of three rules.
