Question

codeigniter 2.1.3 multilanguage website how to ?
i have on /language/english and /language/french
this french
$lang['user_login'] = 'Connecté';
this english
$lang['user_login'] = 'Login';
the language file its called user_lang.php
on the controller contructor i have this :
$this->load->helper('url');
$this->load->helper('language');
on the function index i have this :
public function index()
{
$this->lang->load('user', 'french');
....
on the view i have the following :
<div class="pageTitle"><?php echo $this->lang->line('user_login');?></div>
/*
| -------------------------------------------------------------------
| Auto-load Language files
| -------------------------------------------------------------------
| Prototype:
|
| $autoload['language'] = array('lang1', 'lang2');
|
| NOTE: Do not include the "_lang" part of your file. For example
| "codeigniter_lang.php" would be referenced as array('codeigniter');
|
*/
$autoload['language'] = array('user');
the question is that the website is working its going to the user_lang.php
to get the word login
but only goes to the english file
$this->lang->load('user', 'french');
iam doing this above , and its not working never reads the french file
i have another question , how can i get this working so i can switch languages with a anchor or href
thanks

Answer 1

I would create a function like:
function language($language){
$language = urldecode($language);
switch($language){
case "French":
$this->session->set_userdata('lang_id', 2);
$this->session->set_userdata('lang_name', 'french');
redirect('/', 'refresh');
break;
case "Russian":
$this->session->set_userdata('lang_id', 3);
$this->session->set_userdata('lang_name', 'russian');
redirect('/', 'refresh');
break;
default: //default is English
$this->session->set_userdata('lang_id', 1);
$this->session->set_userdata('lang_name', 'english');
redirect('/', 'refresh');
break;
}
}
And I would change languages navigating to: http://www.domain.com/controller/language/French
Then in every controller or in constructor of each controller class I would check for the lang_id and lang_name session. If sessions are set, I would use them. Else the default language from the config will automatically load. For example:
$lang = $this->session->userdata('lang_name');
if(!isset($lang)){ //load default language
$this->lang->load('home');
$data = array(
'title' => lang('page_title')
);
//etc etc
}else{ //load language from session
$this->lang->load('home', $this->session->userdata('lang_name'));
$data = array(
'title' => lang('page_title')
);
//etc etc
}

Answer 2

in my welcome controller
public function french()
{
$this->session->set_userdata('lang_id', 2);
$this->session->set_userdata('lang_name', 'french');
$DContent['page_details'] = array('page_title' => 'Index of onplans');
$Dheader = array();
$Dsidebar = array();
$Dfooter = array();
$Dmeta = array('meta_title'=>'Welcome to onplans','meta_descricao'=>'onplans');
$this->template->write_view('meta', 'html/meta', $Dmeta, true);
$this->template->write_view('header', 'html/header', $Dheader, true);
$this->template->write_view('content', 'onplans/frenchset', $DContent,true);
$this->template->write_view('sidebar', 'html/sidebar');
$this->template->write_view('footer', 'html/footer');
$this->template->render();
}
public function english()
{
$this->session->set_userdata('lang_id', 3);
$this->session->set_userdata('lang_name', 'english');
$DContent['page_details'] = array('page_title' => 'Index of onplans');
$Dheader = array();
$Dsidebar = array();
$Dfooter = array();
$Dmeta = array('meta_title'=>'Welcome to onplans','meta_descricao'=>'onplans');
$this->template->write_view('meta', 'html/meta', $Dmeta, true);
$this->template->write_view('header', 'html/header', $Dheader, true);
$this->template->write_view('content', 'onplans/englishset', $DContent,true);
$this->template->write_view('sidebar', 'html/sidebar');
$this->template->write_view('footer', 'html/footer');
$this->template->render();
}
on the destination controller called user
$this->load->helper('url');
$this->load->helper('language');
print_r('lang_session'.$this->session->userdata('lang_name'));
$lang = $this->session->userdata('lang_name');
if(!isset($lang)){ //load default language
$this->lang->load('user');
}else{ //load language from session
print_r('lang :'.$this->session->userdata('lang_name'));
$this->lang->load('user',$this->session->userdata('lang_name')); //);
}
now its working
