[英]Zend framework 2 - How to make a language switcher
I am developing a Zend Framework 2 Application and now I want to implement a language switcher from where guest/registered user can choose the language they want, the thing I can't understand is how is it made in Zend Framework 2 using the storage ( not from urls ), I want to keep the preffered language of guest in the storage once he selects one, and for the registered users I can retrieve the preffered one from cookie/database and reuse it with storage. 我正在开发一个Zend Framework 2应用程序,现在我想实现一个语言切换器,客户/注册用户可以从中选择他们想要的语言,我无法理解的是如何在Zend Framework 2中使用存储(不是来自网址),我想在客户选择一个时保留客户的优先语言,对于注册用户,我可以从cookie /数据库中检索优先级,并将其重新用于存储。 But where and how should I start/implement this? 但是我应该在哪里以及如何开始/实施这个? Thank you in advance. 先感谢您。
Setup your Locales
in your global.config.php
: 在global.config.php
设置您的Locales
:
'locale' => array(
'default' => 'en_US',
'available' => array(
'de_DE' => 'Deutsch',
'nl_NL' => 'Dutch',
'en_US' => 'English',
'fr_FR' => 'French',
),
),
So in your Application\\Module.php
you can add a method which sets the default Zend\\Translator\\Translator
: 因此,在Application\\Module.php
您可以添加一个设置默认Zend\\Translator\\Translator
:
class Module {
public function onBootstrap(MvcEvent $e)
{
$applicaton = $e->getApplication();
$serviceManager = $application->getServiceManager();
// Just a call to the translator, nothing special!
$serviceManager->get('translator');
$this->initTranslator($e);
// Etc, more of your bootstrap function.
}
protected function initTranslator(MvcEvent $event)
{
$serviceManager = $event->getApplication()->getServiceManager();
// Zend\Session\Container
$session = New Container('language');
$translator = $serviceManager->get('translator');
$translator
->setLocale($session->language)
->setFallbackLocale('en_US');
}
}
So now the default Locale is en_US as the session has no Locale available. 所以现在默认的Locale是en_US,因为会话没有可用的Locale。 For changing the locale you need to catch the users input and validate the available locales you support, provided in your global.config.php
. 要更改区域设置,您需要捕获用户输入并验证您支持的可用区域设置,在global.config.php
提供。 So in order to change it you might need to add a controller action which catches the input of the user and sets the new locale. 因此,为了更改它,您可能需要添加一个控制器操作,该操作捕获用户的输入并设置新的区域设置。 Example of the controller action without any form usage! 没有任何表单用法的控制器操作示例!
public function changeLocaleAction()
{
// New Container will get he Language Session if the SessionManager already knows the language session.
$session = new Container('language');
$language = $this->getRequest()->getPost()->language;
$config = $this->serviceLocator->get('config');
if (isset($config['locale']['available'][$language]) {
$session->language = $language;
$this->serviceLocator->get('translator')->setLocale($session->language);
}
}
The session allows the users to change their locale and remember it until the session ends, so they won't need to change it when they get back after a while. 会话允许用户更改他们的区域设置并记住它直到会话结束,因此他们在一段时间后回来时不需要更改它。 Hope this will help you and can help you to write some code to save it for your registered users on your application. 希望这对您有所帮助,并可以帮助您编写一些代码,以便为您的应用程序上的注册用户保存。
I am not sure, my approach will work or not. 我不确定,我的方法是否有效。 Please try: 请试试:
We can have 3 params for translate
method. translate
方法我们可以有3个参数。
$translator->translate($message, $textDomain, $locale);
The $locale parameter is taken from the locale, set in the translator and that's why we usually not set manually in the code. $ locale参数取自语言环境,在转换器中设置,这就是我们通常不在代码中手动设置的原因。 So, you can use like below : 所以,您可以使用如下:
$localeVar = 'de_DE'; OR $localeVar = 'en_US'; // according to user's selection
echo $this->translate("Translate me", $textDomain, $localeVar);
You can have a key value pair - key can be user selected language and value can be any one of the language. 您可以拥有一个键值对 - 键可以是用户选择的语言,值可以是任何一种语言。
array(
'english' => 'en_US',
'deutch' => 'de_DE',
'frecnh' => 'fr_FR',
// other language
);
