php Codeigniter 更改加载的语言

Codeigniter Change loaded language

提问by coder

Currently i have a language loaded inside MY_Controller which extends CI_Controller. But inside a special page which controller (let's call it ABC controller) extends MY_Controller, I need to override the loaded language with another language. I tried loading another language inside this ABC controller, but unsuccessful. Is there a way to unload the loaded language and load another language?

目前我在 MY_Controller 中加载了一种语言，它扩展了 CI_Controller。但是在控制器（我们称之为 ABC 控制器）扩展 MY_Controller 的特殊页面中，我需要用另一种语言覆盖加载的语言。我尝试在这个 ABC 控制器中加载另一种语言，但没有成功。有没有办法卸载加载的语言并加载另一种语言？

Have you tried just loading the language file you need?

你试过只加载你需要的语言文件吗？

$this->lang->load('filename', 'language');

It should be then accessible just like your default language. I haven't tested this tho, but from my understanding this should be the way to go about it.

然后它应该可以像您的默认语言一样访问。我还没有测试过这个，但根据我的理解，这应该是解决问题的方法。

REVISED

修改

I ended up digging a bit more for you, and found that you CANNOT load a default language (define it as default in your controller) and then later try to change it to something else.

我最终为您挖掘了更多内容，发现您无法加载默认语言（在控制器中将其定义为默认语言），然后尝试将其更改为其他语言。

Follow these steps:

按着这些次序：

• If you need a language OTHER than english (default), set that in your config.
• If you want to load ANOTHER language on a controller basis, you need to define that (most commonly in your constructorusing something like session array / user selection.
• You cannot load 2 languages (1 in the constructor, then another in a different class.. won't work!)

• 如果您需要英语以外的语言（默认），请在您的配置中进行设置。
• 如果你想在控制器的基础上加载另一种语言，你需要定义它（最常见的是在你constructor使用诸如会话数组/用户选择之类的东西。
• 你不能加载 2 种语言（1 种在构造函数中，然后另一种在不同的类中......不会工作！）

an easier way is to reset the language data and is_loaded

更简单的方法是重置语言数据和 is_loaded

$this->lang->is_loaded = array();
$this->lang->language = array();

I know it's a bit late to answer this but I think you can change the config item 'language' dynamically based on page requirement.

我知道回答这个问题有点晚了，但我认为您可以根据页面要求动态更改配置项“语言”。

$this->config->set_item('language', 'chinese');
$this->config->set_item('language', 'english'); // based on the language folder of course holding language files

I had a requirement to send newsletters in users base lang, and this helped me change the language on the fly, hope this might help..

我需要在用户群 lang 中发送时事通讯，这帮助我即时更改语言，希望这可能会有所帮助..

I encounter this problem and find a tricky solution.

我遇到了这个问题并找到了一个棘手的解决方案。

$this->lang->load('text', 'english');
echo $this->lang->line('__YOUR_LANG_VARIABLE__');

//CI will record your lang file is loaded, unset it and then you will able to load another
//unset the lang file to allow the loading of another file
if(isset($this->lang->is_loaded)){
    for($i=0; $i<=sizeof($this->lang->is_loaded); $i++){
        unset($this->lang->is_loaded[$i]);
    }
}

$this->lang->load('text', 'chinese');
echo $this->lang->line('__YOUR_LANG_VARIABLE__');

Hope it helps.

希望能帮助到你。

If you have any application installed built in codeigniterand you want add a language pack, just follow these steps:

如果您安装了任何内置应用程序codeigniter并且想要添加语言包，只需按照以下步骤操作：

1. Add language files in folder application/language/arabic
(I added arabic lang in sma2 built in ci)
2. Go to the file named setting.php
In application/modules/settings/views/setting.phpyou will find the array:

1. 在文件夹中添加语言文件 application/language/arabic
（我在 ci 内置的 sma2 中添加了阿拉伯语 lang）
2. 转到名为的文件 setting.php
在application/modules/settings/views/setting.php你会发现数组：

<div class="controls">

    <?php /*

  $lang = array (
      'english' => 'English',

      'arabic' => 'Arabic',  // +++ Add this line

      'spanish' => 'Espa?ol'

Now save and run the application.

现在保存并运行应用程序。
