internal server error with htaccess rewrite rule - php

Question

I'm trying to take a URL with multiple querystring parameters into a folder structure URL and am getting a 500 internal server error.
My incoming URL looks like
www.fivestarprofessional.com/ag?PY=16&PF=wm&MKT=Delaware
My destination URL I need written as
delaware.fivestarprofessional.com/16/wm/index.html
I created 3 RewriteCond statements to capture the parameters and a RewriteRule to create the output
RewriteCond %{QUERY_STRING} !^(PY=.*)$ [NC]
RewriteCond %{QUERY_STRING} !^(PF=.*)$ [NC]
RewriteCond %{QUERY_STRING} !^(MKT=.*)$ [NC]
RewriteRule %3.fivestarprofessional.com/%1/%2/index.html
Any assistance would be greatly appreciated.

Answer 1

You can use this rule for your redirection:
RewriteCond %{QUERY_STRING} (?:^|&)PY=([^&]+) [NC]
RewriteCond %1::%{QUERY_STRING} (.*?)::(?:|.*&)PF=([^&]+) [NC]
RewriteCond %1/%2::%{QUERY_STRING} (.*?)::(?:|.*&)MKT=([^&]+)
RewriteRule ^ag/?$ http://%2.fivestarprofessional.com/%1/index.html? [L,NC,NE,R=302]
% variables are captured only from the most recent condition using same %{QUERY_STRING}

Answer 2

Try this one:
RewriteCond "%{QUERY_STRING}" "^PY=([^&]+).*&PF=([^&]+).*&MKT=([^&]+)" [NC]
RewriteRule "www.fivestarprofessional.com/ag" "%3.fivestarprofessional.com/%1/%2/index.html"
The following issues have been corrected:
RewriteRule takes 3 arguments instead of 2.
Arguments to RewriteCond hadn't been enclosed in quotes.
The backreferences into the RewriteCond rules ...
... only refer to the last condition matched (pointed out by #anubhava, being documented in the apache httpd docs). Therefore, the rules need to be collapsed in one.
... referred to the parameter name plus the complete remainder of the query string
... would have matched against query string starting with the respective ul parameter due to the use of the ^ anchor.
... would have been empty anyway, as the rules fired when the patterns did not match ( use of ! prefix )
Recommended reading is the proper section of the apache httpd documentation.
The solution as it stands assumes that...
the query string starts with the url parameter PY
the order in which the url parameters PY, PF, MKT appear in the query string is fixed.
