Question

我是Codeigniter，我需要用户使用动态语言。

我在标题中添加了下拉菜单，我希望允许用户在前端更改网站的语言。

我试图用一个控制器中的以下代码更改语言

if(jQuery("input:radio[name=type]").is(":checked")){
   // do stuff
}

但它没有改变它的语言

我还尝试在我的一个控制器中使用以下代码进行会话

$this->config->set_item('language','spanish');

并尝试在配置文件中访问此变量，但它也无效。

帮助我完成这项工作。

最后我获得成功制作多语言

按照以下步骤

MY_Lang.php文件夹

中的

application\core个文件

MY_Lang.php
<?php  
(defined('BASEPATH')) OR exit('No direct script access allowed');

class MY_Lang extends CI_Lang
{
    function __construct() {

        global $URI, $CFG, $IN;

        $config =& $CFG->config;

        $index_page    = $config['index_page'];
        $lang_ignore   = $config['lang_ignore'];
        $default_abbr  = $config['language_abbr'];
        $lang_uri_abbr = $config['lang_uri_abbr'];
        #exit('my_lang');   
        #print_r($URI); 
        /*if($index_page=='es')
        {
            #$config['index_page'] = 'es';
            #$config['lang_uri_abbr'] = 'es';
            #$IN->set_cookie('user_lang', 'es', $config['sess_expiration']);
            #$URI->uri_string = str_replace('es','en',$URI->uri_string);
            }
        else{
            #$config['index_page'] = 'en';
            #$config['lang_uri_abbr'] = 'en';
            #$IN->set_cookie('user_lang', 'en', $config['sess_expiration']);
            }
        /* get the language abbreviation from uri */
       $uri_abbr = $URI->segment(1);
        #$uri_abbr='es';    
        /* adjust the uri string leading slash */
        #print $URI->uri_string;
        $URI->uri_string = preg_replace("|^\/?|", '/', $URI->uri_string);



        if ($lang_ignore) {

            if (isset($lang_uri_abbr[$uri_abbr])) {

                /* set the language_abbreviation cookie */
                $IN->set_cookie('user_lang', $uri_abbr, $config['sess_expiration']);

            } else {

                /* get the language_abbreviation from cookie */
                 $lang_abbr = $IN->cookie($config['cookie_prefix'].'user_lang');

            }

            if (strlen($uri_abbr) == 2) {

                /* reset the uri identifier */
                 $index_page .= empty($index_page) ? '' : '/';
              //  exit('654');
                /* remove the invalid abbreviation */
                $URI->uri_string = preg_replace("|^\/?$uri_abbr\/?|", '', $URI->uri_string);

                /* redirect */
                header('Location: '.$config['base_url'].$index_page.$URI->uri_string);
                exit;
            }

        } else {

            /* set the language abbreviation */
            $lang_abbr = $uri_abbr;
        }

        /* check validity against config array */
        if (isset($lang_uri_abbr[$lang_abbr])) {


           /* reset uri segments and uri string */
           //$URI->_reindex_segments(array_shift($URI->segments)); # this is commented becasue this is giving error : @$hok : 09/August/2015
           $URI->uri_string = preg_replace("|^\/?$lang_abbr|", '', $URI->uri_string);

           /* set config language values to match the user language */
           $config['language'] = $lang_uri_abbr[$lang_abbr];
           $config['language_abbr'] = $lang_abbr;


           /* if abbreviation is not ignored */
           if ( ! $lang_ignore) {

                   /* check and set the uri identifier */
                   $index_page .= empty($index_page) ? $lang_abbr : "/$lang_abbr";

                /* reset the index_page value */
                $config['index_page'] = $index_page;
           }

           /* set the language_abbreviation cookie */               
           $IN->set_cookie('user_lang', $lang_abbr, $config['sess_expiration']);

        } else {

            /* if abbreviation is not ignored */   
            if ( ! $lang_ignore) {                   

                   /* check and set the uri identifier to the default value */    
                $index_page .= empty($index_page) ? $default_abbr : "/$default_abbr";

                if (strlen($lang_abbr) == 2) {

                    /* remove invalid abbreviation */
                    $URI->uri_string = preg_replace("|^\/?$lang_abbr|", '', $URI->uri_string);
                }
                /*echo '<pre>';
                print_r($_SERVER);
                print_r($config['base_url'].$index_page.$URI->uri_string);
                exit;*/
                $q = $_SERVER['QUERY_STRING'];
                if($q)
                    $q = "/?".$q;
                /* redirect */
                header('Location: '.$config['base_url'].$index_page.$URI->uri_string.$q);
                exit;
            }

            /* set the language_abbreviation cookie */                
            $IN->set_cookie('user_lang', $default_abbr, $config['sess_expiration']);
        }

        log_message('debug', "Language_Identifier Class Initialized");
    }
}

/* translate helper */
function t($line) {
    global $LANG;
//print_r($LANG);
//  exit;
    return ($t = $LANG->line($line)) ? $t : $line;
} 
function _t($line,$params=array()) {
    global $LANG;
    if($params){
        echo str_replace(array_keys($params),array_values($params),($t = $LANG->line($line)) ? $t : $line);
    }
    else
        echo ($t = $LANG->line($line)) ? $t : $line;
} ?>

并在config.php中添加了以下内容

$config['language'] = "english";

/* default language abbreviation */
$config['language_abbr'] = "en";

/* set available language abbreviations */
$config['lang_uri_abbr'] = array("en" => "english","es" => "spanish","ca" => "catalan");

/* hide the language segment (use cookie) */
$config['lang_ignore'] = TRUE;

在route.php

中添加了以下代码

$route['^en/(.+)$'] = "$1";
$route['^es/(.+)$'] = "$1";
$route['^ca/(.+)$'] = "$1";

$route['^(\w{2})$'] = $route['default_controller'];
$route['^(\w{2})/(.+)$'] = "$2";

并在语言文件夹中添加语言文件，如下所示

language/catalan 
language/spanish 
language/english

我希望这会有所帮助。

Answer 2

您是否尝试在控制器中添加此内容？

$this->load->helper('language');

Answer 3

在cookie中加载当前语言，并使用cookie中的语言值加载语言文件用户选择语言时的示例使用以下函数将当前语言设置为cookie

   function language($lang = false) {
    if($this->input->get('lang')){ $lang = $this->input->get('lang'); } 
    $folder = 'application/language/';
    $languagefiles = scandir($folder);

    if(in_array($lang, $languagefiles)){
        $cookie = array(
            'name'   => 'lang',
            'value'  => $lang,
            'expire' => '31536000',
            'prefix' => 'my_',
            'secure' => false
        );

        $this->input->set_cookie($cookie);
    }

    $this->config->set_item('language', $lang);

    redirect($_SERVER["HTTP_REFERER"]);
}

然后在主自定义控制器的构造函数上，或者如果您只是扩展CI_Controller，然后在每个控制器的构造函数上加载语言文件等

   $this->lang->load('language_filename', get_cookie('my_lang'));
