selectively grab portion of query string from url via url rewriting in htaccess

Question

I have this in my .htaccess file:

RewriteEngine On
RewriteCond %{THE_REQUEST} /index\.php\?p=(?!admin)(?!superadmin)((?![^&]*?edit)[^\s&]+) [NC]
RewriteCond %{THE_REQUEST} /index\.php\?p=([^\s&]+) [NC]
RewriteRule ^ /%1? [R=301,L,QSA]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/?$ index.php?p=$1 [L,QSA]

This rewrites in both directions. One way from:

domain.com/index.php?p=Home&l=en&m=0

to:

domain.com/Home

and vice versa. What I would like to do is preserve the query string part of the URL that comes after the value of 'p' and pass it along BOTH WAYS.

I was able to do one way, with this code:

RewriteEngine On
RewriteCond %{THE_REQUEST} /index\.php\?p=(?!admin)(?!superadmin)((?![^&]*?edit)[^\s&]+) [NC]
RewriteCond %{THE_REQUEST} /index\.php\?p=([^\s&]+)&p=([^\s&]+) [NC]
RewriteRule ^ /%1?%2? [R=301,L,QSA]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/?$ index.php?p=$1 [L,QSA]

but I can't get the other way right. Can you guys help? I basically want the value of p to be written as part of the URL after the domain and I don't want it to reappear again but I want all the other variables to be appended.

Right now what I get is:

domain.com/Home?m=0?&p=Home&ms=m0&l=en

What is pretty URL for domain.com/Home?m=0?&p=Home&ms=m0&l=en ? — anubhava

This should work for you:

RewriteEngine On

RewriteCond %{THE_REQUEST} /index\.php\?p=((?!(?:admin|superadmin|[^&]*?edit))[^\s&]+)(?:&(\S+))? [NC]
RewriteRule ^ /%1?%2 [R=302,L,NE]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/?$ index.php?p=$1 [L,QSA]

thanks for your suggestion but that yields the same result, which is that the value of "p" is used twice, first as replacement value for pretty url and then as query string

That is not correct. This redirects /index.php?p=Home&ms=m0&l=e to /Home?ms=m0&l=e as you wrote. Most likely your browser has cached results. Test in a new browser or clear cache.

you are CORRECT and I owe you an apology. I stand corrected. When I cleared all the caches I saw the behavior I was hoping to see. Thank you!

I got one final issue with this... the redirect breaks (404) when I have p with a slash in it (like: p=Folder/File) - when there is a slash in the value of "p" domain.com/index.php?p=Folder/File&ms=0 rewrites to domain.com/Folder/File?ms=0 (which is correct) but I get a 404 error even though without the htaccess file the file is found - would really appreciate your help! thanks

Change last rule to: RewriteRule ^(.+?)/?$ index.php?p=$1 [L,QSA]
