我正在开发之前创建的Codeigniter项目。我遇到了这个功能：
public function change_language()
{
$string_value = $this->input->post('lang_code');
$rows = $this->Common_model->getTableData('language', array('code' => $string_value))->row();
$this->session->set_userdata('language',$rows->name);
$this->session->set_userdata('locale',$string_value);
}
数据库：
----------------------------------------
id | code | name | img_path
----------------------------------------
1 | en | English| images/en.png
2 | ru | Russian| images/ru.png
该功能正常工作并加载语言文件的内容。网站正在翻译，所有en / ru的URL保持不变。因为没有，如果非默认页面没有被Google索引。我怎样才能添加＆＃39; ru＆＃39;和＆＃39; ru＆＃39;在域名之后？
途径：
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

| URI ROUTING
| -------------------------------------------------------------------------
| This file lets you re-map URI requests to specific controller functions.
|
| Typically there is a one-to-one relationship between a URL string
| and its corresponding controller class/method. The segments in a
| URL normally follow this pattern:
|
| example.com/class/method/id/
|
| In some instances, however, you may want to remap this relationship
| so that a different class/function is called than the one
| corresponding to the URL.
|
| Please see the user guide for complete details:
|
| http://codeigniter.com/user_guide/general/routing.html
|
| -------------------------------------------------------------------------
| RESERVED ROUTES
| -------------------------------------------------------------------------
|
| There area two reserved routes:
|
| $route['default_controller'] = 'welcome';
|
| This route indicates which controller class should be loaded if the
| URI contains no data. In the above example, the "welcome" class
| would be loaded.
|
| $route['404_override'] = 'errors/page_missing';
|
| This route will tell the Router what URI segments to use if those provided
| in the URL cannot be matched to a valid route.

您想设置example.com/en/controller，example.com/ru/controller？通常不是最佳做法，但这会有所帮助：Building a multi-language navigation menu in CodeIgniter
对我的一个项目有用的是向页面添加?hl=ru参数。
链接将这些引用为<link href="https://example.com/controller?hl=ru" hreflang="ru" rel="alternate">。这使得多语言网站的链接变得干净，对搜索引擎优化来说是最好的，并且在CI中设置起来更容易。
