如何在zend框架视图中使用$ this-> _()? [英] How to use $this->_() in zend framework views?

问题描述

在我的ZF 1.11应用程序中，我将翻译器存储在注册表中，如下所示:

In my ZF 1.11 application I'm storing my translator in registry like this:

Zend_Registry::set('Zend_Translate', $translator);

因此，在我的视图脚本中，我可以通过以下方式访问翻译器:

So in my view scripts I can access the translator this way:

$this->translate('abc');

有什么聪明的方法可以代替使用此呼叫:

Is there any clever way to be able to use this call instead:

$this->_('abc');

使用$ this-> translate使视图混乱，很多人还是习惯于看到_().

Using $this->translate clutters the views, and lot's of people are used to seeing _() anyway.

推荐答案

我通常同意函数/方法名称应该有意义的概念，但我也同意翻译的_()是广泛使用的标准，因此可以接受.

Whereas I generally agree with the notion that function/method names should be meaningful, I also agree that the _() for translations is a widely used standard and therefore acceptable.

您可以通过在中间层添加包装器来实现.例如，以下内容将使该方法可用于所有从MyProject_Controller_Action派生的控制器:

You can do this by adding wrappers to your intermediate layers. For example the following would make the method available to all your controllers derived from MyProject_Controller_Action:

class MyProject_Controller_Action extends Zend_Controller_Action 
{
    protected $translator;

    public function init()
    {
        $this->translator = Zend_Registry::get('Zend_Translate');
    }



   /**
    * Translator wrapper
    * 
    * @param string $string The string to be translated
    * @return string $translated The translated string
    */
    protected function _($string)
    {
        $translated = $this->translator->translate($string);
        return $translated;
    }
}

当然可以使用Zend_View进行同样的操作.

Of course the same can be done with Zend_View.

免责声明:最好的做法是直接调用注册表来使代码混乱.实际上，这是一种反模式，应由DI代替. Zend Framework 2将使我们更容易避免注册表.可以通过实际上通过构造函数将翻译对象注入到类中来改进此代码.

Disclaimer: It is not the best practice to clutter your code with direct calls to the registry. Actually it's an anti-pattern which should be replaced by DI. Zend Framework 2 will make it much easier for us to avoid the registry. This code could be improved by actually injecting the translation object into the class via constructor.
