ZF2-将变量从Module.php渲染到树枝布局 [英] ZF2 - Rendering variables from Module.php to twig layout
问题描述
我正在将ZF2网站从使用默认模板转换为树枝版本的过程中，到目前为止，主要方面，一切进展顺利，除了我在Bootstrap方法中在Module.php中定义了一些变量外我现在无法进入layout.twig模板.
I'm in the midst of converting a ZF2 site from using default templates into twig versions, and so far, for the main part, everything is going well, except I have some variables in Module.php defined from a bootstrap method that I'm now unable to get into the layout.twig template.
适用于默认模板的原始代码如下:
The original code that worked fine for the default templates is as:
public function bootstrapLayout(MvcEvent $e)
{
$config = $e->getApplication()->getServiceManager()->get('applicationconfig');
$authService = $e->getApplication()->getServiceManager()->get('AuthService');
$version = new \stdClass();
$version->major = $config['version']['major'];
$version->minor = $config['version']['minor'];
$dt = new \DateTime();
$thisYear = $dt->format('Y');
$dt->setTimestamp($config['version']['build_date']);
$version->buildDate = $dt->format('d/m/Y H:i');
$user = new \stdClass();
$user->hasIdentity = $authService->hasIdentity();
$user->username = $authService->getStorage()->read('username');
$e->getViewModel()->setVariables(array(
'version' => $version,
'thisYear' => $thisYear,
'user' => $user,
));
}
但是，版本"，"thisYear"或用户"都不会对树枝布局模板有所了解.我在这里进行搜索，找到的最接近的分辨率是通过以下方式获取ZfcTwigRenderer:
However, neither 'version', 'thisYear' nor 'user' make itself known to the twig layout template. I've searched on here and the closest resolution I came to finding was to obtain the ZfcTwigRenderer by:
$zfcTwigRenderer = $e->getApplication()->getServiceManager()->get('ZfcTwigRenderer');
但是现在我不知如何使用它，并将定义的var通过它传递到布局.
but now I'm at a loss how I can utilise this and pass my defined vars through it to the layout.
这是布局文件的内容:

尽管在过去的几个小时中尝试了各种各样的事情，但我确实遇到了一个死胡同，因此在这方面的任何帮助将不胜感激.
Any help on this would be greatly appreciated as I've really come up against a dead end, despite trying all sorts of things for the past couple of hours.
推荐答案
对于在所有布局中都可用的真实全局变量，您需要在Module.php的onBootstrap函数中执行以下操作，因此您的示例将是
For true global variables that are available inside all layouts you need to do the following inside a onBootstrap function in Module.php so you example would be
public function bootstrapLayout(MvcEvent $e)
{
$config = $e->getApplication()->getServiceManager()->get('applicationconfig');
$authService = $e->getApplication()->getServiceManager()->get('AuthService');
$version = new \stdClass();
$version->major = $config['version']['major'];
$version->minor = $config['version']['minor'];
$dt = new \DateTime();
$thisYear = $dt->format('Y');
$dt->setTimestamp($config['version']['build_date']);
$version->buildDate = $dt->format('d/m/Y H:i');
$user = new \stdClass();
$user->hasIdentity = $authService->hasIdentity();
$user->username = $authService->getStorage()->read('username');
$enviroment = $e->getApplication()->getServiceManager()->get('ZfcTwigEnvironment');
$enviroment->addGlobal('version', $version);
$enviroment->addGlobal('thisYear', $thisYear);
$enviroment->addGlobal('user', $user);
}
然后，您将可以像上面所述那样使用上面的模板.
This would then allow you to use your above template like you have set out.
