Hi, I've got this multilanguage system working, it's on a live site. I still have some work on the language switcher, but I've got an idea in mind that has the potential of succeeding. The only thing that is bothering me now are the urls that are the same for the both languages for some particular pages.
Because I'm working with single template for all languages, but with cookies to select the current language.

For example: I'm having a /about page that depending on the cookie returns a result in a different language.
At the moment I have a Dutch and an English version.
I would always need the cookie, because non-page related items I call my "building blocks" are language dependent too (menu, footer, etc.)
Also it allows me to use just a single template and it doesn't matter how many languages are used, it remains very clean.
I can add languages afterwards without having to alter code. I can do it from the admin panel only. I'll show you some code after explaining the current problem.

I would like to add a Dutch url "/over-ons" that is actually the same page as the "/about" page and alter the cookie depending on the fact if the url matches the language of the cookie.
If not I can alter the cookie so it matches the url and therefor all other content can be shown in the same language.

So to make it clear: I would like to have an "/over-ons" url and an "/about" url that would both point to "/about" but keep the requested name (so no redirect but rather masking the actual page name).

I've been messing with the .htaccess, but it doesn't seem to work. I've tried copying the generated .htaccess code from the "about" page and replacing the first part with "over-ons", but no success.

Now the code to help you understand this case (feel free to use it for your own project if you like)

languages.php
Code: Select all
<?php require_once( 'couch/cms.php' ); ?>
<cms:template title="Languages" clonable="1" executable='0'>
    <cms:editable name="language_code" label="Language Code" desc="Ex. EN" type="text"></cms:editable>   
    <cms:editable name="index" label="Index Number" desc="Used for sorting languages" type="text" validator="integer"></cms:editable>
    <cms:editable name="icon" label="Icon" type="image" />
</cms:template>

<?php COUCH::invoke(); ?>


This is the admin template I use for sorting my entries (just link them in the functions to the right templates), this only works with cloned pages, haven't found a way yet to get it to work with nested pages, however the translating itself works, the back-end sorting doesn't
Code: Select all
<cms:php>
    // Set info about selected folder
    global $DB, $CTX, $FUNCS;
   
    $fid = ( isset($_GET['fid']) && $FUNCS->is_non_zero_natural($_GET['fid']) ) ? (int)$_GET['fid'] : null;
    if( $fid ){
        $rs = $DB->select( K_TBL_FOLDERS, array('name'), "id='" . $DB->sanitize( $fid ). "'" );
        if( count($rs) ){
            $fname = $rs[0]['name'];
        }
    }
   
    $CTX->set( 'my_selected_fid', $fid, 'global' );
    $CTX->set( 'my_selected_fname', $fname, 'global' );
   
    if ( isset($_GET['lang']) && preg_match("/^[a-z0-9\-]+$/", $_GET['lang']) ){
        $CTX->set( 'filtered_language', $_GET['lang'], 'global' );
    }

I use the custom_field option and exclude option while listing pages / folders / nested pages (this sometimes requires some looping up front, but not always) to filter out the other languages.

I guess that's about it. This is working really well for me, I hope someone can help me out with the url issue. Then it would almost be perfect :) (but the other flaws aren't bothering me that much)
Hi :) How about embedding 2 different snippets on /about ?
/over-ons would be then a dummy page, always redirecting to /about. In /about you show the content dependent on the selected language. This way it can be manageable..
@trendoman: yes that would work, but it would require to add templates when more languages are added, again resulting in a cluttered admin panel. If I could not display some templates in the admin panel, that would be awesome, I also have this stylesheet just sitting there while it has no input fields since it gets its color settings from my skin template...
So, you got one template for many languages and editables are stacked one under another? If so, how do you show proper editables with cms:pages?
