How reload Twig cache in Symfony 2
提问by Azhar
I have a application which is developed in PHP using the Symfony 2 framework. I have changed a HTML file, but the change is not reflecting when I refresh the page.
我有一个使用 Symfony 2 框架在 PHP 中开发的应用程序。我更改了 HTML 文件,但刷新页面时未反映更改。
I restarted the server. No luck.
I tried to remove the Twig folder from the
/protected/cache/
page itself. This is not loading.
我重新启动了服务器。没运气。
我试图从
/protected/cache/
页面本身中删除 Twig 文件夹。这不是加载。
How can I reload the Twig cache?

- I am using tomcat server to deploy.
- I don't have the Symfony 2 command line configured on the server.
- I am new to PHP.
- 我正在使用 tomcat 服务器进行部署。
- 我没有在服务器上配置 Symfony 2 命令行。

The most simple way, type the command :
最简单的方法,输入命令:
rm -rf app/cache/*
The point is: all files in app/cache/
can be removed freely, they are regenerated when needed.
重点是:里面的所有文件app/cache/
都可以自由删除,需要的时候重新生成。
If you really want to clear only twig cache :
如果您真的只想清除树枝缓存:
rm -rf app/cache/<environment>/twig
Replace <environment>
by dev
, prod
, or test
according to your requirements.
替换<environment>
为dev
、prod
或test
根据您的要求。

When creating a new Twig_Environment instance, you can pass an array of options as the constructor second argument. One of them is auto_reload
. When developing with Twig, it's useful to recompile the template whenever the source code changes. If you don't provide a value for the auto_reload
option, it will be determined automatically based on the debug
value.
创建新的 Twig_Environment 实例时,您可以传递一个选项数组作为构造函数的第二个参数。其中之一是auto_reload
。使用 Twig 进行开发时,每当源代码更改时重新编译模板很有用。如果您不为该auto_reload
选项提供值,它将根据该debug
值自动确定。
Set auto_reload
to be true
:
设置auto_reload
为true
:
$twig = new Twig_Environment($loader, array('auto_reload' => true));

I had a similar problem, but deleting the cache-folder did not have any impact on my template and I don't know why. What seems to solve my problem now is the following code in my config_dev.yml:
我遇到了类似的问题,但删除缓存文件夹对我的模板没有任何影响,我不知道为什么。现在似乎可以解决我的问题的是我的 config_dev.yml 中的以下代码:
twig:
cache: false
Maybe this is also a solution for you, so that you don't need to use the command all the time.
或许这也是你的一个解决方案,这样你就不用一直使用命令了。

If you are using opcache/other similar caching, deleting twig's cache folder won't refresh templates as twig cache consist of only .php files. You need to delete twig's cache folder + execute php file which contains:
如果您使用 opcache/其他类似缓存,删除 twig 的缓存文件夹不会刷新模板,因为 twig 缓存仅包含 .php 文件。您需要删除 Twig 的缓存文件夹 + 执行包含以下内容的 php 文件:
opcache_reset();

You have to do some changes in app.php file located in web folder.
您必须对位于 web 文件夹中的 app.php 文件进行一些更改。
Change:
改变:
$kernel = new AppKernel('prod', false);
to:
到:
$kernel = new AppKernel('prod', true);
and clear the cache if you want.
并根据需要清除缓存。

If you are using OPcache make sure to comment out opcache.validate_timestamps=0
in dev environment.
如果您使用 OPcache,请确保opcache.validate_timestamps=0
在开发环境中注释掉。

you can add a function like this :
您可以添加这样的功能:
public function renderView($view, array $parameters = array())
{
$loader = new \Twig_Loader_Filesystem($this->container->getParameter("template_path"));
$twig = new \Twig_Environment($loader, array('auto_reload' => true,
'cache' => false
));
/////////////////////add a translate filter///////////////////////
$getTextdomain = new \Twig_SimpleFilter('trans',function ($string){
return $this->container->get('translator')->trans($string);
});
$twig->addFilter($getTextdomain);
//////////////////////////////////////////////////////////////////
///////////////////////////Add an extension twig//////////////////
$twig->addExtension(new Extension());
//////////////////////////////////////////////////////////////////
return $twig->render($view, $parameters);
}
