Changing / replace multiple URL parameters with htaccess / mod_rewrite – Apache

I got this working snippet to change a query parameter:

RewriteCond %{QUERY_STRING}  (.*)&?name=(.*)? [NC]
RewriteRule ^pokladna/?$  $0?%1name_gls=%2 [R=301,L]

from here .htaccess rewrite rule with string replacement in url

But in my case I need to replace multiple query parameters.

For example: https://example.com/?utm_source=source&utm_medium=banner&utm_campaign=campaignname

needs to be https://example.com/?mtm_source=source&mtm_medium=banner&mtm_campaign=campaignname

There might be other parameters before, after or in between, which should not be affected.

Thank you!

    With your shown samples, attempts please try following htaccess rules file. Please make sure to clear your browser cache before testing your URLs.

    RewriteEngine ON
RewriteCond %{THE_REQUEST} s/?utm_source=([^&]*)&utm_medium=([^&]*)&utm_campaign=(S+)s [NC]
RewriteRule ^ /?mtm_source=%1&mtm_medium=%2&mtm_campaign=%3 [QSA,L]

    Generic solution:

    RewriteEngine ON
RewriteCond %{THE_REQUEST} s/?(?:[^=]*)=([^&]*)&(?:[^=]*)=([^&]*)&(?:[^=]*)=(S+)s [NC]
RewriteRule ^ /?mtm_source=%1&mtm_medium=%2&mtm_campaign=%3 [QSA,L]

    Here is how you can replace multiple query parameters that start with utm_ to their counterparts that start with mtm_:

    RewriteEngine On

# this rule will find any of the 3 utm_ query parameters and will
# replace each with the mtm_ query parameter. N flag is used here to 
# make this rule loop until all query parameters have been replaced
# in the end it sets an env variable MTM to 1
RewriteCond %{QUERY_STRING} ^(.*&)?u(tm_(?:source|medium|campaign)=[^&]*)(&.*)?$ [NC]
RewriteRule ^ %{REQUEST_URI}?%1m%2%3 [N,DPI,E=MTM:1]

# if env variable MTM is 1 then do an external redirect
RewriteCond %{ENV:MTM} =1
RewriteRule ^ %{REQUEST_URI} [L,R=302,NE]

# other rules go below this line

    Once satisfied with the result replace 302 with 301 (permanent redirect).

    This needs to be tested on a local Apache web server not on any online test facility.
