URL 中加入 语言 判定

gevilrror

因为要做个支持多语言的版本，所以看了ci的语言处理方式，进行了更改

如访问地址为
http://xxx.cn/cn/xxxx
http://xxx.cn/en/xxxx

则进入不同语言版本

处理方法：

在/application/config/config 加入:

PHP复制代码

$config['languages'] = 'cn,en';

复制代码

创建/application/core/MY_Router.php 文件

PHP复制代码

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
 
class MY_Router extends CI_Router {
 
    function __construct()
    {
        parent::__construct();
    }
 
    function _parse_routes()
    {
        /*----------------------------------------------------------------------------------------*/
        $lang = explode(',',$this->config->item('languages'));
 
        // Url have lang?
        if(is_array($lang))
        {
            $lang = array_flip($lang);
 
            if(isset($lang[$this->uri->segments[0]]))
            {
                $this->config->set_item('language',$this->uri->segments[0]);
                $this->uri->segments = array_slice($this->uri->segments, 1);
 
                if (count($this->uri->segments) == 0)
                {
                    return $this->_set_default_controller();
                }
            }
        }
        /*----------------------------------------------------------------------------------------*/
 
        // Turn the segment array into a URI string
        $uri = implode('/', $this->uri->segments);
 
        // Is there a literal match?  If so we're done
        if (isset($this->routes[$uri]))
        {
            return $this->_set_request(explode('/', $this->routes[$uri]));
        }
 
        // Loop through the route array looking for wild-cards
        foreach ($this->routes as $key => $val)
        {
            // Convert wild-cards to RegEx
            $key = str_replace(':any', '.+', str_replace(':num', '[0-9]+', $key));
 
            // Does the RegEx match?
            if (preg_match('#^'.$key.'$#', $uri))
            {
                // Do we have a back-reference?
                if (strpos($val, '$') !== FALSE AND strpos($key, '(') !== FALSE)
                {
                    $val = preg_replace('#^'.$key.'$#', $val, $uri);
                }
 
                return $this->_set_request(explode('/', $val));
            }
        }
 
        // If we got this far it means we didn't encounter a
        // matching route so we'll set the site default route
        $this->_set_request($this->uri->segments);
    }
}
 
/* End of file MY_Router.php */
/* Location: ./application/core/MY_Router.php */
