gettext setup not working

I had gettext working, but now it suddenly won't translate. I get find out whats going on. I am trying to use /sys/locale/no开发者_C百科_NO/LC_MESSAGES/messages.po to translate the page to norwegian.

/public/home.php

$locale = "en_US";
if (isSet($_COOKIE['lang'])) $locale = $_COOKIE['lang'];
putenv("LC_ALL=$locale");
setlocale(LC_ALL, $locale);
bindtextdomain("messages", "../sys/locale");
textdomain("messages");

echo "<p>locale: " . $locale . " "; 
echo gettext("Home"); 
exit(); 

This prints out

locale: no_No Home when I should be locale: no_No Hjem

I see you are fighting with norwegian. I had the problem with Debian servers too which just support nb_NO and nn_NO but not no_NO. The solution is to use the exact names of locale names as folder and setting:

Make sure you have the locales installed:

$ locale -a
C
POSIX
en_US.utf8
nb_NO.utf8
nn_NO.utf8

So the php setting for norwegian bokmål:

setlocale(LC_ALL, 'nb_NO.utf8');
putenv('LANGUAGE=nb_NO.utf8');

The path to the PO files should have the same name e.g.:

./i18n/nb_NO.utf8/LC_MESSAGES/messages.po

I guess the same solution will work for Ubuntu.

With Japanese I have to do the following:

putenv("LANG=ja_JP.UTF-8");
setlocale(LC_MESSAGES, 'ja_JP.UTF-8');
bindtextdomain('messages', '../locale');
bind_textdomain_codeset('messages', 'UTF-8');
textdomain('messages');

With other languages I find I do not always have to add the encoding suffix, it is very inconsistent. Similarly I cannot just use "ja" when "en" works fine.

setlocale returns false unless the locale is listed in /usr/share/i18n/SUPPORTED but translations will often work despite the error.

You might need to reconfigure locales:

Install debconf (I.e. Run apt-get update then apt-get install debconf, as root)

Run dpkg-reconfigure locales as root

This code worked for me:

//Put this in cookie for example

$lang = GetPrefLanguage($_SERVER["HTTP_ACCEPT_LANGUAGE"]);

$language = $lang . '.utf8';

setlocale(LC_ALL, $language);

// Set language
putenv('LANG='.$language);

// Specify location of translation tables
bindtextdomain('traductions', dirname(__FILE__).'/locale');

// Choose domain
textdomain("traductions");

// Translation is looking for in ./locale/xx_XX/LC_MESSAGES/traductions.mo now
/*GET Pref language */
function GetPrefLanguage($str_http_languages)
{
    $lang = substr($str_http_languages, 0, 2);

    switch($lang) {
        case 'fr':
            return 'fr_FR';
        break;
        case 'de':
            return 'de_DE';
        break;
        case 'en':
            return 'en_US';
        break;
        default:
            return 'en_US';
    }
}
