What i would like to do is like Apache is to use multiple map files and  
get the vars form them

i have tried the following and can only get one value `$variable1`  
what is a rewrite to get `$variable1` and `$variable2` in one rewrite

rewrite ^(^/_)/(._)$ /index.php?key1=$variable1&key2=$variable2 last;

map $uri $variable1 {  
default 11;  
/sub 7;

}  
map $uri $variable2 {  
default 78;  
/pep 23;  
}

Regards, David

What are you trying to accomplish?

If your URI is /sub $variable1 becomes 7.

If your URI is /sub $variable2 becomes 23.

It works as it should. I don’t see any issue. Also your rewrite is  
unnecessary. Try this:

return 301 /index.php?key1=$variable1&key2=$variable2;

Do you mean that the request URI can contain both /pep and /sub?Like  
this:

[http://example.com/sub/pep/other-stuff-if-any](http://example.com/sub/pep/other-stuff-if-any)

If so then your matching must be done with a regex:

map $uri $variable1 {  
default 11;  
~/sub 7;  
}

map $uri $variable2 {  
default 78;  
~/pep 23;  
}

I confess I’m not sure exactly what it is you are trying to do.

For certain urls, grab parts of the url and send them as-is within  
QUERY\_STRING to a php-processor? (In which case: doing the grabbing in  
the location definition is probably easiest.)

Or grab parts of the url, and set other values in QUERY\_STRING based  
on the url parts? (In which case, matching on $uri at server level and  
using the map-ped value within the location block is probably easiest.)

Or maybe something else?

The map documentation is at [GitHub - nginxinc/nginx-wiki: ARCHIVED -- Source for the now archived NGINX Wiki section of https://www.nginx.com · GitHub](http://wiki.nginx.org/HttpMapModule#map)  
and there’s an example of if/set/map in the thread at  
[http://forum.nginx.org/read.php?2,194480](http://forum.nginx.org/read.php?2,194480)

And there are examples of php-without-rewrite around as well – in the  
location block, set “fastcgi\_param SCRIPT\_FILENAME” explicitly, as well  
as fastcgi\_pass.

Good luck,
