Symfony 2根据用户代理属性加载不同的模板 [英] Symfony 2 load different template depending on user agent properties
问题描述
是否可能(以及如何)
- 确定用户是否正在使用移动设备
- 在这种情况下,强制symfony 2加载不同的模板
- (并使用默认的html模板)
id想要做的是在不修改任何控制器的情况下加载不同的模板.
What id like to do is, to load different templates without modifying any controller.
更新
这并不是真正的问题所在,它与symfony无关.可以在控制器级别上完成(加载不同的模板):
It wasn't the detection part the real issue here, it's really nothing to do with symfony. It can be done (load different template) on a controller level:
public function indexAction()
{
$format = $this->isMobile() ? 'mob' : 'html';
return $this->render('AcmeBlogBundle:Blog:index.'.$format.'.twig');
}
但是可以在全球范围内完成吗?就像服务一样,或者是在每次请求之前执行的东西,并在模板规则中进行更改.
But can it be done globally? Like a service, or something that execute before every request, and make changes in the templating rules.
推荐答案
好,所以我没有完整的解决方案,但只不过在哪里可以找到一个:)
Ok, so I don't have a full solution but a little more than where to look for one :)
您可以在app/config/config.yml中指定用于模板化项目的加载程序(服务)
You can specify loaders (services) for templating item in app/config/config.yml
framework:
esi: { enabled: true }
#translator: { fallback: %locale% }
secret: %secret%
router:
resource: "%kernel.root_dir%/config/routing.yml"
strict_requirements: %kernel.debug%
form: true
csrf_protection: true
validation: { enable_annotations: true }
templating:
engines:
- twig
loaders: [moby.loader]
default_locale: %locale%
trust_proxy_headers: false
session: ~
然后定义所提到的加载程序服务:
Then define the mentioned loader service:
services:
moby.loader:
class: Acme\AppBundle\Twig\Loader\MobyFilesystemLoader
arguments: ["@templating.locator", "@service_container"]
之后,定义您的加载程序服务类:
After that define your loader service class:
namespace Acme\AppBundle\Twig\Loader;
use Symfony\Bundle\FrameworkBundle\Templating\Loader\FilesystemLoader;
use Symfony\Component\Templating\Storage\FileStorage;
class MobyFilesystemLoader extends FilesystemLoader
{
protected $container;
public function __construct($templatePathPatterns, $container)
{
parent::__construct($templatePathPatterns);
$this->container = $container;
}
public function load(\Symfony\Component\Templating\TemplateReferenceInterface $template)
{
// Here you can filter what you actually want to change from html
// to mob format
// ->get('controller') returns the name of a controller
// ->get('name') returns the name of the template
if($template->get('bundle') == 'AcmeAppBundle')
{
$request = $this->container->get('request');
$format = $this->isMobile($request) ? 'mob' : 'html';
$template->set('format', $format);
}
try {
$file = $this->locator->locate($template);
} catch (\InvalidArgumentException $e) {
return false;
}
return new FileStorage($file);
}
/**
* Implement your check to see if request is made from mobile platform
*/
private function isMobile($request)
{
return true;
}
}
如您所见,这并不是完整的解决方案,但我希望至少可以为您指明正确的方向.
As you can see this isn't the full solution, but I hope that this, at least, points you to the right direction.
刚发现有一个捆绑包具有移动检测功能,带有自定义的树枝引擎,该引擎根据发送请求的设备来呈现模板文件 ZenstruckMobileBundle ,尽管我从没用过... :)
Just found out that there is a bundle with mobile detection capabilities, with custom twig engine that renders template file depending on a device that sent request ZenstruckMobileBundle, although I never used it so... :)
