Set global language value in Yii2 application
提问by bxN5
Where can I set language (based on user's cookie) globally? How to make it work in the whole application (controllers,views, etc.) ?
我可以在哪里设置全局语言（基于用户的 cookie）？如何让它在整个应用程序（控制器、视图等）中工作？
In documentation I found \Yii::$app->language = '';but, where I can write my logic to change the language in right way?
在我找到的文档中 \Yii::$app->language = '';，我可以在哪里编写逻辑来以正确的方式更改语言？

You can set your base language in the configuration file. In the basic application it's default location is: /config/web.php, in advanced: application-name/config/main.phpand application-name/config/main-local.php.
您可以在配置文件中设置基本语言。在基本应用程序中，它的默认位置是：/config/web.php、高级：application-name/config/main.php和application-name/config/main-local.php。
$config = [
'id' => 'basic',
'language' => 'nl', // Set the language here
'basePath' => dirname( __DIR__ ),
'bootstrap' => ['log'],
...
];

You should use
你应该使用
\Yii::$app->language = '';
inside the controller that is parent to all your controllers. The parent class should be inside the components folder, and if it is not available than create the component with something like
在所有控制器的父级控制器中。父类应该在 components 文件夹内，如果它不可用，则使用类似的东西创建组件
use yii\web\Controller;
class MyController extends Controller
{
public function init()
{
parent::init();
#add your logic: read the cookie and then set the language
}
}
After that, you have to be sure that all your controllers extends your newly created MyController instead of the original one.
之后，您必须确保所有控制器都扩展了新创建的 MyController 而不是原始控制器。
I hope it helps.

The accepted answer is a very good one, but just in case you want something "even more global" you can use the bootstrap functionality, or the "on beforeAction" to trigger a function (both via the configuration):
接受的答案是一个很好的答案，但万一您想要“更加全局”的东西，您可以使用引导功能或“on beforeAction”来触发功能（均通过配置）：
Bootstrap:
引导程序：
$config = [
...
'bootstrap' => ['your\own\component'],
...
];
You can then use the init()-function of that component for example.
例如，您可以使用该init()组件的-function。
"on beforeaction":
“在行动之前”：
$config = [
'on beforeAction' => function($event) {
// set language
}
];

I know this is old but, I found this question while I was searching an answer. I also find a nice guide, link below.
我知道这很旧，但是我在寻找答案时发现了这个问题。我还找到了一个很好的指南，链接如下。
One of the ways to do it to create a component and bootstrap it, like so:
创建组件并引导它的方法之一，如下所示：
Create a file in, say, common/components/LanguageSelector.php
在 common/components/LanguageSelector.php 中创建一个文件
<?php
namespace common\components;
use yii\base\BootstrapInterface;
class LanguageSelector implements \yii\base\BootstrapInterface
{
public $supportedLanguages = [];
public function bootstrap($app)
{
$preferredLanguage = $app->request->getPreferredLanguage($this->supportedLanguages);
$app->language = $preferredLanguage;
}
}
I'm using advanced app template, you can adjust the file location and namespace as needed.
我正在使用高级应用程序模板，您可以根据需要调整文件位置和命名空间。
Then, in your config file, you need to add this component, just like you are adding another component like debug, or log components, like so:
然后，在您的配置文件中，您需要添加此组件，就像添加另一个组件（如调试或日志组件）一样，如下所示：
'components' => [
'languageSelector' => [
'class' => 'common\components\LanguageSelector',
'supportedLanguages' => ['en-US', 'tr-TR'],
],
],
Also, you need to add this component to bootstrapped components in your config file:
此外，您需要将此组件添加到配置文件中的引导组件中：
'bootstrap' => ['languageSelector', ...]
This approach does not rely on cookies however, it relies on the language of the client browser. You also can find an example on below page in how to achieve preference based language selection. But basically what you need to do is, in your languageSelector component, getting the value from the cookie and change the language accordingly. If there is not a cookie present in the user browser, you can fallback to the browser language.
然而，这种方法不依赖于 cookie，它依赖于客户端浏览器的语言。您还可以在下面的页面中找到有关如何实现基于偏好的语言选择的示例。但基本上您需要做的是，在您的 languageSelector 组件中，从 cookie 中获取值并相应地更改语言。如果用户浏览器中不存在 cookie，您可以回退到浏览器语言。

There are many answer to your question, depending on your logic. If you have a static rule:
你的问题有很多答案，这取决于你的逻辑。如果您有静态规则：
return [
...
'language' => 'it',
...
];
See http://www.yiiframework.com/doc-2.0/guide-tutorial-i18n.html#configuration
见http://www.yiiframework.com/doc-2.0/guide-tutorial-i18n.html#configuration
If you want implement the ordinary HTTP content negotiation, you have a dedicated component:
如果你想实现普通的 HTTP 内容协商，你有一个专门的组件：
return [
...
'components' => [
...
'contentNegotiator' => [
'class' => 'yii\filters\ContentNegotiator',
'languages' => ['en', 'it'],
],
...
],
];
See http://www.yiiframework.com/doc-2.0/guide-structure-filters.html#content-negotiator
见http://www.yiiframework.com/doc-2.0/guide-structure-filters.html#content-negotiator
If you need a more complex negotiation, you can create a bootstrap component. Here is an example where the language is taken from user preferences for a logged in user or negotiated for guests. Note that you can overload your application with complex operations, like taking the supported languages from a database.
如果您需要更复杂的协商，您可以创建一个引导程序组件。这是一个示例，其中语言取自登录用户的用户偏好或为客人协商。请注意，您可以使用复杂的操作来重载您的应用程序，例如从数据库中获取支持的语言。
/**
* Select a language from user preferences or content negotiation
*/
class LanguageSelector implements BootstrapInterface
{
public function bootstrap($app)
{
if (\Yii::$app->user->isGuest) {
$supportedLanguages = (new \yii\db\Query())
->select('iso639_1')
->from('language')
->orderBy(['priority' => SORT_ASC])
->column();
$app->language = $app->request->getPreferredLanguage($supportedLanguages);
} else {
$app->language = Language::findOne(\Yii::$app->user->identity->language_id)->iso639_1;
}
}
}

Go to application configuration file frontend/main/config.php or backend/main/config.php
转到应用程序配置文件 frontend/main/config.php 或 backend/main/config.php
$config = ['language' => 'ru-RU']
$config = ['语言' => 'ru-RU']

Roman, you can achieve your goal using a main configuration file or param. Just make a variable like $sitelang = 'UK_ua';then you can use it via Yii::$app->params['sitelang']
Roman，您可以使用主配置文件或参数来实现您的目标。只需创建一个变量，$sitelang = 'UK_ua';然后您就可以通过Yii::$app->params['sitelang']
