.htaccess - htaccess to redirect root and sulbfolders language pages to /en

Question

I would like to use htaccess to redirect www.domain.com/?lang=en pages to www.domain.com/en/ subfolders. I've tried the code below but url with subfolders like www.domain.com/folder/?lang=en or www.domain.com/folder/subfolder/?lang=en are not taken into account by my htaccess rules. Only the root page is well updated from ?lang=en to /en/.

• (KO) domain.com/?lang=en > domain.com/en/

• (KO) domain.com/folder/?lang=en > domain.com/en/folder/

• (KO) domain.com/folder/folder2/?lang=en > domain.com/en/folder/folder2/

Here is what i've tried so far :

# BEGIN LANGUAGE REDIRECTION
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{QUERY_STRING} lang=en
# exclude all requests starting with /wp-admin/
RewriteCond %{REQUEST_URI} !^/wp-admin/.*$
RewriteRule ^(.*) /en/$1? [L,R=301]
</IfModule>
# END LANGUAGE REDIRECTION

Based on your shown samples, could you please try following. Please make sure you clear your browser cache before testing your URLs. This will redirect/rewrite and will add language en in your case(as per shown samples) before your URIs.

RewriteEngine ON
RewriteCond %{QUERY_STRING} ^lang=(.*) [NC]
RewriteRule ^(.*)$ %1/$1 [R=301,NE,QSD,L]
