Codeigniter Multi-lang將lang代碼添加到URL（set_userdata）

Question

我正在開發先前創建的Codeigniter項目。我就遇到了這個功能：

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); 
    } 

數據庫：

---------------------------------------- 
    id | code | name | img_path  
---------------------------------------- 
    1 | en | English| images/en.png 
    2 | ru | Russian| images/ru.png 

功能工作正常，並加載語言文件的內容。該網站正在翻譯的URL保持相同的所有兩個EN/RU。由於這個原因，如果非默認頁面沒有被Google編入索引，那麼沒有。我如何在域後添加'ru'和'ru'？

途徑：

<?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:

| 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.

Answer 1

你想要設置example.com/en/controller，example.com/ru/controller？一般不是最佳做法，但這將有助於：Building a multi-language navigation menu in CodeIgniter

對我的一個項目有效的是爲頁面添加?hl=ru參數。 鏈接引用那些作爲<link href="https://example.com/controller?hl=ru" hreflang="ru" rel="alternate">。這使得多語言網站鏈接乾淨，這是最好的搜索引擎優化，它更容易在CI設置。

Answer 2

您可以依賴路由。這取決於你的應用程序的結構。在做多語言網站時，我使用https://github.com/devtime-share/codeigniter-kitlang。還有/的文檔裏面是優雅的解決方案，裏面routes.php文件

$group_langs = 'en|es|fr'; 
$route["($group_langs)"] = $route['default_controller']; 
$route["($group_langs)/(:any)$"] = "$2"; 

把什麼當談到搜索引擎優化，你應該建立規範的網址，並考慮使用的hreflang靶向網站https://support.google.com/webmasters/answer/189077的替換版本，也發生儘可能多的信息，你可以在站點地圖內。
