在 YII 中更改语言 [英] Change language in YII

问题描述

使用 YII 创建新站点后，我在 protected/messages 中添加了一个文件夹fr"，并添加了一个文件site.php"，其中包含:

After creating a new site with YII, I added a folder 'fr' in protected/messages and added a file 'site.php' which contains:

返回数组('hello' => 'bonjour');

return array('hello' => 'bonjour');

在view/layout/main.php中，我添加了以下代码:

in the view/layout/main.php, I added following code:

<?php 
    // I change the language to english and french using session. 
    //  This is just for example.
    Yii::app()->language = 'fr'; 

    // I also used Yii::app()->setLanguage('fr');
    echo Yii::t('site','hello');
?>

但是语言没有翻译..我哪里错了.请推荐

But the language is not translated.. Where am I wrong. Please suggest

推荐答案

如果您希望翻译在所有视图中正常工作，您应该在控制器中设置语言.

You should set language in the controller if you want translations to work properly in all views.

为了将语言应用于所有控制器，在组件文件夹中创建新的 Controller.php 文件，其中包含扩展 CController 的 class Controller，然后所有的控制器都应该扩展 Controller 类.在 Controller 类中覆盖 init() 方法(不要忘记调用 parent::init())并在那里设置语言.例如:

In order for language to be applied to all Controllers, create in components folder new Controller.php file with class Controller which extends CController, and then all your controllers should extend Controller class. in Controller class override init() method (don't forget to call parent::init()) and set language there. For example:

class Controller extends CController
{
    public $layout='//layouts/column1';

    function init()
    {
        parent::init();
        Yii::app()->language = 'fr';
    }
 }

通过这种方式，您可以在一个地方添加应应用于所有控制器的其他内容

This way you can add additional things which should apply to all Controllers at one place
