CI使用session和hooks实现多语言切换以及自动检查浏览器语言
我不会说话，直接主题了哈！嘿嘿。使用session实现的picklanguage.phpapplication/hooks/pickLanguage.php
function pickLanguage()
{
require APPPATH.'/config/language.php';
// Re-populate $_GET
parse_str($_SERVER['QUERY_STRING'], $_GET);
// If we've been redirected from HTTP to HTTPS on admin, ?session= will be set to maintain language
if ($_SERVER['SERVER_PORT'] == 443 and ! empty($_GET['session']))
{
session_start($_GET['session']);
}
else
{
//session_start();
}
// Lang set in URL via ?lang=something
if ( ! empty($_GET['lang']))
{
// Turn en-gb into en
$lang = strtolower(substr($_GET['lang'], 0, 2));
log_message('debug', 'Set language in URL via GET: '.$lang);
}
// Lang has already been set and is stored in a session
elseif ( ! empty($_SESSION['langCode']))
{
$lang = $_SESSION['langCode'];
log_message('debug', 'Set language in Session: '.$lang);
}
// Lang has is picked by a user.
elseif ( ! empty($_COOKIE['langCode']))
{
$lang = strtolower($_COOKIE['langCode']);
log_message('debug', 'Set language in Cookie: '.$lang);
}
// Still no Lang. Lets try some browser detection then
elseif ( $config['checkHttpAcceptLanguage'] and ! empty($_SERVER['HTTP_ACCEPT_LANGUAGE']))
{
// explode languages into array
$acceptLangs = explode(',', $_SERVER['HTTP_ACCEPT_LANGUAGE']);
$supportedLangs = array_keys($config['supportedLanguages']);
log_message('debug', 'Checking browser languages: '.implode(', ', $acceptLangs));
// Check them all, until we find a match
foreach ($acceptLangs as $acceptLang)
{
if (strpos($acceptLang, '-') === 2)
{
// Turn pt-br into br
$lang = strtolower(substr($acceptLang, 3, 2));
// Check its in the array. If so, break the loop, we have one!
if (in_array($lang, $supportedLangs))
{
log_message('debug', 'Accept browser language: '.$acceptLang);
break;
}
}
// Turn en-gb into en
$lang = strtolower(substr($acceptLang, 0, 2));
// Check its in the array. If so, break the loop, we have one!
if (in_array($lang, $supportedLangs))
{
log_message('debug', 'Accept browser language: ' . $acceptLang);
break;
}
}
}
// If no language has been worked out - or it is not supported - use the default
if (empty($lang) or ! array_key_exists($lang, $config['supportedLanguages']))
{
$lang = $config['supportedLanguages'];
log_message('debug', 'Set language default: ' . $lang);
}
// Whatever we decided the lang was, save it for next time to avoid working it out again
if (function_exists('get_instance') && !class_exists('session'))
{
$sessionLibrary = get_instance()->load->library('session');
$sessionLibrary->session->set_userdata('langCode', $lang);
}
// Load CI config class
$CIcConfig =& load_class('Config');
// Set the language config. Selects the folder name from its key of 'en'
$CIcConfig->set_item('language', $config['supportedLanguages'][$lang]['folder']);
// Sets a constant to use throughout ALL of CI.
define('AUTO_LANGUAGE', $lang);
log_message('debug', 'Defined const AUTO_LANGUAGE: '. AUTO_LANGUAGE);
}

MYController.php
application/config/You controller.php
// Lock front-end language
//这里是检测在那里使用，我这里是在后台使用。
if ( ! (is_a($this, 'AdminController') and ($siteLang = AUTO_LANGUAGE)))

$siteLanguage = explode(',', Settings::get('sitePublicLang'));
if (in_array(AUTO_LANGUAGE, $siteLanguage))

// We can't have a blank language. If there happens to be a blank language, let's default to English.
if ( ! $siteLang )

$langs = $this->config->item('supportedLanguages');
$brocade['lang'] = $langs;
$brocade['lang']['code'] = CURRENT_LANGUAGE;
$this->load->vars($brocade);
浏览器输入host.com/lang=cn试试吧。。。嘿嘿！确保语言包有当前的语言哦！
我觉得该赞一下，大家之所以选择CI，就是想发挥一下自己的创造性，否则用其他的框架，什么都做好了，只要当搬运工即可。
修复pickLanguage.php 正常使用
function pickLanguage()
{
require APPPATH.'/config/language.php';
$sessionLibrary = NULL;
// Load CI session class, if is class not exists.
if (function_exists('get_instance') && ! class_exists('session'))
{
$sessionLibrary = get_instance()->load->library('session');
}
if ( ! is_object($sessionLibrary) )
{
show_error('Class Session not exists.', 500);
}
// Re-populate $_GET
parse_str($_SERVER['QUERY_STRING'], $_GET);
// If we've been redirected from HTTP to HTTPS on admin, ?session= will be set to maintain language
if ($_SERVER['SERVER_PORT'] == 443 and ! empty($_GET['session']))
{
session_start($_GET['session']);
}
// Lang set in URL via ?lang=something
if ( ! empty($_GET['lang']))
{
// Turn en-gb into en
$lang = strtolower(substr($_GET['lang'], 0, 2));
log_message('debug', 'Set language in URL via GET: '.$lang);
}
// Lang has already been set and is stored in a session
elseif ( ! empty($sessionLibrary->session->userdata('langCode')))
{
$lang = $sessionLibrary->session->userdata('langCode');
log_message('debug', 'Set language in Session: '.$lang);
}
// Lang has is picked by a user.
elseif ( ! empty($_COOKIE['langCode']))
{
$lang = strtolower($_COOKIE['langCode']);
log_message('debug', 'Set language in Cookie: '.$lang);
}
// Still no Lang. Lets try some browser detection then
elseif ( $config['checkHttpAcceptLanguage'] and ! empty($_SERVER['HTTP_ACCEPT_LANGUAGE']))
{
// explode languages into array
$acceptLangs = explode(',', $_SERVER['HTTP_ACCEPT_LANGUAGE']);
$supportedLangs = array_keys($config['supportedLanguages']);
log_message('debug', 'Checking browser languages: '.implode(', ', $acceptLangs));
// Check them all, until we find a match
foreach ($acceptLangs as $acceptLang)
{
if (strpos($acceptLang, '-') === 2)
{
// Turn pt-br into br
$lang = strtolower(substr($acceptLang, 3, 2));
// Check its in the array. If so, break the loop, we have one!
if (in_array($lang, $supportedLangs))
{
log_message('debug', 'Accept browser language: '.$acceptLang);
break;
}
}
// Turn en-gb into en
$lang = strtolower(substr($acceptLang, 0, 2));
// Check its in the array. If so, break the loop, we have one!
if (in_array($lang, $supportedLangs))

break;

}
}
// If no language has been worked out - or it is not supported - use the default
if (empty($lang) or ! array_key_exists($lang, $config['supportedLanguages']))
{
$lang = $config['supportedLanguages'];
log_message('debug', 'Set language default: ' . $lang);
}
// Whatever we decided the lang was, save it for next time to avoid working it out again
$sessionLibrary->session->set_userdata('langCode', $lang);
// Load CI config class
$CIConfig =& load_class('Config');
// Set the language config. Selects the folder name from its key of 'en'
$CIConfig->set_item('language', $config['supportedLanguages'][$sessionLibrary->session->userdata('langCode')]['folder']);
// Sets a constant to use throughout ALL of CI.
define('AUTO_LANGUAGE', $sessionLibrary->session->userdata('langCode'));
log_message('debug', 'Defined const AUTO_LANGUAGE: '. AUTO_LANGUAGE);
}
为什么不通过 CI自带的Lang函数呢{:1_1:} ci的执行效率要高一些。 感謝，參考
