如何在Codeigniter中更改站点语言

Question

I have developed website in codeigniter and now i want it to be multi-language.

I have followed a tutorial working with hooks. Here is my hook.php

$hook['post_controller_constructor']=array(
                                   'class'=>'LanguageLoader',
                                   'function'=>'initialize',
                                   'filename'=>'LanguageLoader.php',
                                   'filepath'=>'hooks'
                                   );

and I have created a class and placed it inside the hooks folder.

class LangSwitch extends CI_Controller
{
    public function __construct()
    {
        parent::construct();
        $this->load->helper('url');
    }

   function switchLanguage($language="")
   {
       $language=($language!="") ? $language:"english"; 
       $this->session->set_userdata('site_lang',$language);
       redirect(base_url());
   }
}

and here is another file which is also placed inside the hooks folder

class LanguageLoader
{
    function initialize()
    {
        $CI=&get_instance();
        $CI->load->helper('language');
        $site_lang=$CI->session->userdata('site_lang');
        if($site_lang)
        {
            $CI->lang->load('dari','dari');
        }
        else
        {
            $CI->lang->load('english','english');
        }
    }
}

and here is my view file.

<a href='<?=site_url('LangSwitcher/switchLanguage/english')?>'>English</a>

and it says that "The requested page was not found ". Can any body find it what is happening ?

Answer 1

Your controller is called LangSwitch but in your url, you generate "LangSwitch er " in site_url(...) . If you don't have routes set up for this then it's probably a typo there.

Also, the if($site_lang) condition looks wrong in LanguageLoader . Maybe you wanted if ($site_lang == "dari") and elseif s to other supported languages or a switch()
