CodeIgniter动态语言功能 [英] CodeIgniter dynamic language functionality
问题描述
我是Codeigniter,我需要用户动态语言。
I am Codeigniter and i need dynamic language for users.
我在标题中添加了下拉菜单,我希望允许用户更改网站的语言
I have added drop-down at the header and i want to allow users to change language of site at the frontend.
我试图在一个控制器中使用以下代码更改语言
i tried to change language with below code in one controller
$this->config->set_item('language','spanish');
但是它不能正常工作,并且语言不会改变
but its not working its not changing language
我也尝试在我的一个控制器中使用以下代码进行会话
i also tried with taking session with below code in one of my controller
$mylanguage = $this->session->set_userdata(array('my_language',$dynamiclang));
,并尝试访问配置文件中的此变量,但它也无法正常工作。
and tried to access this variable in config file but its also not working.
帮我完成这项工作。
推荐答案
最后,我成功地制作了多国语言
Finally I Got Success to make multi language
遵循以下步骤
MY_Lang.php
文件应用程序\核心
文件夹
MY_Lang.php
<?php
(defined('BASEPATH')) OR exit('No direct script access allowed');
class MY_Lang extends CI_Lang
{
function __construct() {
global $URI, $CFG, $IN;
$config =& $CFG->config;
$index_page = $config['index_page'];
$lang_ignore = $config['lang_ignore'];
$default_abbr = $config['language_abbr'];
$lang_uri_abbr = $config['lang_uri_abbr'];
#exit('my_lang');
#print_r($URI);
/*if($index_page=='es')
{
#$config['index_page'] = 'es';
#$config['lang_uri_abbr'] = 'es';
#$IN->set_cookie('user_lang', 'es', $config['sess_expiration']);
#$URI->uri_string = str_replace('es','en',$URI->uri_string);
}
else{
#$config['index_page'] = 'en';
#$config['lang_uri_abbr'] = 'en';
#$IN->set_cookie('user_lang', 'en', $config['sess_expiration']);
}
/* get the language abbreviation from uri */
$uri_abbr = $URI->segment(1);
#$uri_abbr='es';
/* adjust the uri string leading slash */
#print $URI->uri_string;
$URI->uri_string = preg_replace("|^\/?|", '/', $URI->uri_string);
if ($lang_ignore) {
if (isset($lang_uri_abbr[$uri_abbr])) {
/* set the language_abbreviation cookie */
$IN->set_cookie('user_lang', $uri_abbr, $config['sess_expiration']);
} else {
/* get the language_abbreviation from cookie */
$lang_abbr = $IN->cookie($config['cookie_prefix'].'user_lang');
}
if (strlen($uri_abbr) == 2) {
/* reset the uri identifier */
$index_page .= empty($index_page) ? '' : '/';
// exit('654');
/* remove the invalid abbreviation */
$URI->uri_string = preg_replace("|^\/?$uri_abbr\/?|", '', $URI->uri_string);
/* redirect */
header('Location: '.$config['base_url'].$index_page.$URI->uri_string);
exit;
}
} else {
/* set the language abbreviation */
$lang_abbr = $uri_abbr;
}
/* check validity against config array */
if (isset($lang_uri_abbr[$lang_abbr])) {
/* reset uri segments and uri string */
//$URI->_reindex_segments(array_shift($URI->segments)); # this is commented becasue this is giving error : @$hok : 09/August/2015
$URI->uri_string = preg_replace("|^\/?$lang_abbr|", '', $URI->uri_string);
/* set config language values to match the user language */
$config['language'] = $lang_uri_abbr[$lang_abbr];
$config['language_abbr'] = $lang_abbr;
/* if abbreviation is not ignored */
if ( ! $lang_ignore) {
/* check and set the uri identifier */
$index_page .= empty($index_page) ? $lang_abbr : "/$lang_abbr";
/* reset the index_page value */
$config['index_page'] = $index_page;
}
/* set the language_abbreviation cookie */
$IN->set_cookie('user_lang', $lang_abbr, $config['sess_expiration']);
} else {
/* if abbreviation is not ignored */
if ( ! $lang_ignore) {
/* check and set the uri identifier to the default value */
$index_page .= empty($index_page) ? $default_abbr : "/$default_abbr";
if (strlen($lang_abbr) == 2) {
/* remove invalid abbreviation */
$URI->uri_string = preg_replace("|^\/?$lang_abbr|", '', $URI->uri_string);
}
/*echo '<pre>';
print_r($_SERVER);
print_r($config['base_url'].$index_page.$URI->uri_string);
exit;*/
$q = $_SERVER['QUERY_STRING'];
if($q)
$q = "/?".$q;
/* redirect */
header('Location: '.$config['base_url'].$index_page.$URI->uri_string.$q);
exit;
}
/* set the language_abbreviation cookie */
$IN->set_cookie('user_lang', $default_abbr, $config['sess_expiration']);
}
log_message('debug', "Language_Identifier Class Initialized");
}
}
/* translate helper */
function t($line) {
global $LANG;
//print_r($LANG);
// exit;
return ($t = $LANG->line($line)) ? $t : $line;
}
function _t($line,$params=array()) {
global $LANG;
if($params){
echo str_replace(array_keys($params),array_values($params),($t = $LANG->line($line)) ? $t : $line);
}
else
echo ($t = $LANG->line($line)) ? $t : $line;
} ?>
并在config.php中添加以下内容
and added below things in config.php
$config['language'] = "english";
/* default language abbreviation */
$config['language_abbr'] = "en";
/* set available language abbreviations */
$config['lang_uri_abbr'] = array("en" => "english","es" => "spanish","ca" => "catalan");
/* hide the language segment (use cookie) */
$config['lang_ignore'] = TRUE;
在route.php中的代码下面添加了
added below code in route.php
$route['^en/(.+)$'] = "$1";
$route['^es/(.+)$'] = "$1";
$route['^ca/(.+)$'] = "$1";
$route['^(\w{2})$'] = $route['default_controller'];
$route['^(\w{2})/(.+)$'] = "$2";
并在如下所示的语言文件夹中添加语言文件
and added language files in language folder like below
language/catalan
language/spanish
language/english
我希望这会有所帮助。
