Combine two Mod Rewrite Rules

Current Status: Firstly, I would like to point out that this question is very much related to a question which I posted two days ago. I have since tried to tackle the problem I was facing a different way and have encountered different problems. I hope this does not constitute any sort of "double-post"?

I have created two mod rewrite rules which seem to work in isolation to create the desired effect. These are shown below:

RewriteCond %{QUERY_STRING} (.*)
RewriteRule ^(.*/)?([A-Za-z0-9.-]+)_([A-Za-z0-9.-]*) $1?$2=$3&%1 [L]

The above rule takes a URL like this:

www.site.com/param1/thing/sortorder_5/getparam2_6/

and converts it into this:

www.site.com/param1/thing/?sortorder=5&getparam2_6/

The second rule is as follows:

RewriteCond %{QUERY_STRING} (.*)
RewriteRule ^(.*/)?((?:cmd)[^/]*)/((?!(?:cmd)[.+]*)(.+)) $1?$2=$3&%1 [L]

This takes a URL like this:

http://www.site.com/cmd/param1/thing/cmd2/param2/

and converts it into this:

http://www.site.com?cmd=param1/thing&cmd2=param/

Desired Outcome:

I would like to merge these two rewrite rules so that I may be able to do the following:

http://www.site.com/cmd/param1/cmd2/param2/sortorder_5

converts to:

http://www.site.com?cmd=param1&cmd2=param2&sortorder=5

Anybody who tells me how to begin doing so would be most kind. I have experimented with LOTS of mod rewrite code for days, with no luck. My regex/mod rewrite knowledge really isn't up to scratch, so my apologies for that! The whole mod rewrite code is pasted below. Thank you.

RewriteEngine On

# This block works fine in isolation
RewriteCond %{QUERY_STRING} (.*)
RewriteRule ^(.*/)?([A-Za-z0-9.-]+)_([A-Za-开发者_JS百科z0-9.-]*) $1?$2=$3&%1 [L]

# This block also works fine in isolation
RewriteCond %{QUERY_STRING} (.*)
RewriteRule ^(.*/)?((?:cmd)[^/]*)/((?!(?:cmd)[.+]*)(.+)) $1?$2=$3&%1 [L]

# This block should append the query string to index.php (front controller)
RewriteCond %{QUERY_STRING} ^(.*)$
RewriteRule ^.*$ index.php?%1 [L]

This is tested and works:

RewriteEngine On
RewriteRule ^(cmd[^/]*)/([^/]+)/?(.*)$ $3?$1=$2 [QSA,NC,L]
RewriteRule ^([a-z\d.-]+)_([a-z\d.-]+)/?(.*)$ $3?$1=$2 [QSA,NC,L]

See mod_rewrite docs about the flags.

Example request:

http://localhost:8080/test/cmd1/foo/cmd2/bar/foo_bar/cmd42/everything

Ends up at:

http://localhost:8080/test/index.pl?cmd42=everything&foo=bar&cmd2=bar&cmd1=foo

With the .htaccess located at /test/, and index.pl printing its query string:

cmd42=everything&foo=bar&cmd2=bar&cmd1=foo

This request has the redirect log:

This log can be seen by adding this in your server config:

RewriteLog "logs/rewrite.log"
RewriteLogLevel 2
