Matching random string after a domain.

[Ais]

Hey, I'm struggling with my regex, as I'm trying to create a image upload site, but with nicer urls.

I need a rewrite on my (nginx) vhost that rewrites any 5 character random string to readable url for my script.

For example, http://example.com/Is1Rt would rewrite into http//example.com/upload.php?picture_id=Is1Rt.

According to this thing, I think:

if (!-e $request_filename) {
    rewrite ^/([0-9a-z]{5}$ /upload.php?picture_id=$1 last;
}

According to this thing, I think:

if (!-e $request_filename) {
    rewrite ^/([0-9a-z]{5}$ /upload.php?picture_id=$1 last;
}

 

Thank you!

It works perfectly with few modifications.

if (!-e $request_filename) {
               rewrite "^/([0-9a-zA-Z]){5}$" /upload.php?picid=$1 last;
          }
