Htaccess multilanguage mod_rewrite

Question

Ok, I've wasted a lot of time trying to figure this out but the more I'm trying to learn about rewriting rules, the less I seem to understand what's going on. I need to fix some rewriting rules for a codeigniter based project.

The application is a multilanguage CMS that basically works with modules, pages and posts and in a .htaccess file I need to check if the url is a page or a post and redirect to a appropriate controller.

So far in my .htaccess file i have the following:

    #if I'm on the homepage and i have a language id
    RewriteCond $1 ^([a-z]{2})/?$
    RewriteRule ^(.*)$ index.php?homepage/index/$1 [PT,L]

    #if module - this works ok when there is no language id
    RewriteCond $1 ^(gallery|post|products)
    RewriteRule ^(.*)$ index.php?$1 [PT,L]

    # Rewrite all other URLs to index.php/URL - page controller
    RewriteRule ^(.*)$ index.php?page/show/$0 [PT,L]

With the code above, if I enter

http://mydomain.com/gallery/something/9

everything is fine and dandy, dut if I add a language id like so:

http://mydomain.com/en/gallery/something/9

it doesn't work anymore, and I get a page not found/404 error from the page controller (redirect at the end of .htaccess).

So let's say that i have urls that can look something like this:

    http://mydomain.com/gallery/something/9       
    http://mydomain.com/en/gallery/something/25
    http://mydomain.com/fr/post/something/31

I need to somehow redirect those urls to

     http://mydomain.com/gallery/something/9        
     http://mydomain.com/en/gallery/somethingelse/25
     http://mydomain.com/fr/post/somethingelse/31

Notice that sometimes I have language id, and sometimes I don't. Is this something that I should be doing by using htaccess? Is Codeigniter routing a better alternative? Thank you for any help Stack Overflow :)

Try that:

RewriteCond $1 ^[^/]*/?(gallery|post|products)
