[wp-hackers] Multilanguage: how to redefine locale on the fly

[Manuel Schmalstieg]

Update: I'm now inclined to use a workaround based on the post slug.
This makes the language switch as simple as this:

function wpsx89972_redefine_locale($locale) {
    $wpsx_url = $_SERVER['REQUEST_URI'];
    $wpsx_url_lang = substr($wpsx_url, -4);
    if ( $wpsx_url_lang == "-fr/") {
        $locale = 'fr_FR';
    } else if ( $wpsx_url_lang == "-en/") {
        $locale = 'en_US';
    } else { // fallback to default
        $locale = 'de_DE';
    }
    return $locale;
}
add_filter('locale','wpsx89972_redefine_locale',10);

Still a bit disappointed as I would prefer a fully taxonomy-based
method... but at least I now have a working multi-language solution in
13 lines of code, not that bad \o/

Thanks again for the great advice!
