Wildcard subdomain mod-rewrite does not work - php

Question

I have a wildcard subdomain *.domain.com assigned to public_html/.
I want to do like this:
For example, /folder1/index.php is based on state name(?state=statename).
For the /folder1/folder2/index.php, it will be based on unique name(?name=uniquename).
So, www.domain.com/folder1/index.php?state=statename will be statename.domain.com
and www.domain.com/folder1/folder2/index.php?name=uniquename will be uniquename.domain.com
This is my code
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+folder1/index\.php\?state=([^\s&]+) [NC]
RewriteRule ^ http://%1.domain.com/? [R=301,L]
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+folder1/folder2/index\.php\?name=([^\s&]+) [NC]
RewriteRule ^ http://%1.domain.com/? [R=301,L]
The problem is it redirect back to public_html directory. Is there any problem with the code?
Old Code
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www.domain.com$ [NC]
RewriteRule ^$ /index [L]
RewriteCond %{HTTP_HOST} !^www.domain.com$ [NC]
RewriteCond %{HTTP_HOST} ^(www.)?([^.]+).domain.com$ [NC]
RewriteRule ^(index)/?$ /$1.php?name=%2 [L,NC,QSA]
Code explanation : Whenever user enter uniquename.domain.com, it will automatically go to www.domain.com/index.php?name=uniquename and the uniquename.domain.com in url bar would not change.
The differences for the new problem is there are different state directory and the domain would be state1.uniquename.domain.com. The 'state1.uniquename.domain.com' in the url bar should not change too.

Based on your comments. Make sure DOCUMENT_ROOT for www.domain.com, state1.domain.com, state2.domain.com is public_html
Try this code:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+folder1/index\.php\?state=([^\s&]+) [NC]
RewriteRule ^ http://%1.domain.com/? [R=301,L]
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+folder1/folder2/index\.php\?name=([^\s&]+) [NC]
RewriteRule ^ http://%1.domain.com/? [R=301,L]
RewriteCond %{REQUEST_URI} !\.(?:jpe?g|gif|bmp|png|tiff|css|js)$ [NC]
RewriteCond %{HTTP_HOST} ^([^.]+)\.([^.]+)\.domain\.com$ [NC]
RewriteRule ^ /state/%1/client/index.php?name=%2&page=%{REQUEST_URI} [L,NC]
