Codeigniter语言

Question

我想创建一个多语言网站,但我不希望语​​言出现在URI中,例如example.com/fr/about(我不想这样).我只是想改变文字语言.我的问题是,我所做的第一种加载语言是永远的.为什么？如果我做:

$this->config->set_item(‘language’,‘english’);
$this->lang->load(‘messages’);
$this->config->set_item(‘language’,‘french’);
$this->lang->load(‘messages’);

要么

$this->lang->load(‘messages’,‘english’);
$this->lang->load(‘messages’,‘french’);

只是英文出现了.我怎样才能解决这个问题？

我的配置语言自动加载是空的.

谢谢您的帮助.

我为此使用了一个钩子.

function pick_language() {

    require_once(APPPATH.'/config/language.php');

    session_start();

    // Lang set in URL via ?lang=something
    if(!empty($_GET['lang']))
    {
        // Turn en-gb into en
        $lang = substr($_GET['lang'], 0, 2);
        $_SESSION['lang_code'] = $lang;
    }

    // Lang has already been set and is stored in a session
    elseif( !empty($_SESSION['lang_code']) )
    {
        $lang = $_SESSION['lang_code'];
    }

    // Lang has is picked by a user.
    // Set it to a session variable so we are only checking one place most of the time
    elseif( !empty($_COOKIE['lang_code']) )
    {
        $lang = $_SESSION['lang_code'] = $_COOKIE['lang_code'];
    }

    // Still no Lang. Lets try some browser detection then
    else if (!empty( $_SERVER['HTTP_ACCEPT_LANGUAGE'] ))
    {
        // explode languages into array
        $accept_langs = explode(',', $_SERVER['HTTP_ACCEPT_LANGUAGE']);

        log_message('debug', 'Checking browser languages: '.implode(', ', $accept_langs));

        // Check them all, until we find a match
        foreach ($accept_langs as $lang)
        {
            // Turn en-gb into en
            $lang = substr($lang, 0, 2);

            // Check its in the array. If so, break the loop, we have one!
            if(in_array($lang, array_keys($config['supported_languages'])))
            {
                break;
            }
        }
    }

    // If no language has been worked out - or it is not supported - use the default
    if(empty($lang) or !in_array($lang, array_keys($config['supported_languages'])))
    {
        $lang = $config['default_language'];
    }

    // Whatever we decided the lang was, save it for next time to avoid working it out again
    $_SESSION['lang_code'] = $lang;

    // Load CI config class
    $CI_config =& load_class('Config');

    // Set the language config. Selects the folder name from its key of 'en'
    $CI_config->set_item('language', $config['supported_languages'][$lang]['folder']);

    // Sets a constant to use throughout ALL of CI.
    define('CURRENT_LANGUAGE', $lang);
}

这不仅会为您设置正确的语言,而且会为您提供一个常量CURRENT_LANGUAGE,其中包含他们正在使用的语言('en','de'等).

可用的语言来自配置项:

/*
|--------------------------------------------------------------------------
| Supported Languages
|--------------------------------------------------------------------------
|
| Contains all languages your site will store data in. Other languages can
| still be displayed via language files, thats totally different.
| 
| Check for HTML equivalents for characters such as ? with the URL below:
|    http://htmlhelp.com/reference/html40/entities/latin1.html
|
*/
$config['supported_languages'] = array(
    'en'=> array('name' => 'English', 'folder' => 'english'),
    'es'=> array('name' => 'Español', 'folder' => 'spanish'),
    'fr'=> array('name' => 'Français', 'folder' => 'french'),
    'de'=> array('name' => 'German', 'folder' => 'german')
);

/*
|--------------------------------------------------------------------------
| Default Language
|--------------------------------------------------------------------------
|
| If no language is specified, which one to use? Must be in the array above
|
|   en
|
*/
$config['default_language'] = 'en';

这将从GET(http://somesite.com/?lang=de)中选择正确的语言,然后检查会话变量(由正确匹配填充),然后检查浏览器是否接受lang标头.

首先使用匹配中的任何一个.

阅读开发者指南,有一些事情需要考虑:

• "必须使用_lang.php命名语言文件作为文件扩展名." - 你的文件叫做"消息"
• 对不同语言使用不同的文件
• $this->lang->load("messages");如果没有第二个参数,只需加载默认语言
• 用英文显示翻译文本 $this->lang->line('some_key');
