Question

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

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: 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

But can not be:

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

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

Thanks,

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]

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