Changing / replace multiple URL parameters with htaccess / mod_rewrite

Question

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]
