Best place to set application language

hesam.khaki · November 3, 2015, 2:28pm

I have a multi language application and user’s desired language is reflected in urls:

mysite.com/<languageCode>/page/12

…

so I have to wait for UrlManager to set $_GET[‘language’] parameter for me to know what is this request’s language.

My question is, when and where is the best time and place for me to use $_GET[‘language’] parameter and set Yii::$app->language based on it. It would be great if could be done in bootstrapping but that’s too soon and UrlManager has no yet set $_GET[‘language’] in that phase. I’m currently using onBeforeAction event in my application config:




'on beforeAction' => function ($event) {

        kalpok\i18n\LanguageSetter::setup();

},

any idea? better place for it? or that’s just fine there?

is there an event like on afterParseRequest ?

i suggest the init() function of your controller.

as you say, you have to wait the UrlManager, maybe you could also preload the UrlManager in the bootstrap-property of your config, have a look here:

My app has several modules and controllers, I prefer a single place for it. also having all controllers extend a parent just for this reason does not feel right to me.

I preloaded UrlManager as you said, but it seems preloading it does not make it run parseRequest() method which is what’s needed here.

so could you try to preload yii\web\UrlRule and all other neccessary classes?

Selecting application language
==============================

When developing applications or websites for global marked, supporting multiple languages is always a requirement.
Yii has built in solution for handling message translations but doesn’t provide anything about selecting a language
because implementation depends of requirements.

In this recipe we’ll describe some typical cases of language selection and provide ideas and code snippets so you’ll
be able to pick what’s required and implement it in your project.

## How to set application language

Setting application language is pretty simple. It can be done either via code like the following:

```php
Yii::$app->language = 'ru_RU';
```

or via application config such as `config/main.php`:
