htaccess for multiple optional parameters - regex

Question

My mission is to achieve
http://localhost/projectname/media/video
from
http://localhost/projectname/index.php?m=media&cmd=video
and also
http://localhost/projectname/home
http://localhost/projectname/index.php?m=home
Below the files helps to achieve my mission
RewriteRule ^([^/]*)$ /projectname/index.php?m=$1
RewriteRule ^([^/]*)/([^/]*)$ /projectname/index.php?m=$1&cmd=$2
the thing is that any external files such as javascript and css would not be taken into play.
i know my alternative is to put this is htaccess
RewriteRule ^([^/]*)/cmd/([^/]*)$ /projectname/index.php?m=$1&cmd=$2
which enables http://localhost/projectname/media/cmd/video
I would like to make it without the CMD. Any suggestions?

Answer 1

Change your rules to this:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]*)/([^/]*)/?$ projectname/index.php?m=$1&cmd=$2 [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]*)/?$ projectname/index.php?m=$1 [L,QSA]
And make sure your js, css, images files are using absolute path not the relative ones. Which means their paths should either start with http:// or /.

Answer 2

why not just pass everything to index.php and then handle/parse the path, e.g.
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
Then use
$_SERVER['PATH_INFO']
$_SERVER['ORIG_PATH_INFO']
$_SERVER['QUERY_STRING']
