我的twig模板" backoffice.html.twig" 位于 Egov / AdminBundle 并扩展 baseBO.html.twig
它包含此块
{% block notificationD %} {% endblock %}
并在 Egov / PosteBundle / Controller / CcpAdminController.php 我有这个功能
public function getDemandeEnCourAction()
{
$repo = $this ->getDoctrine()
->getManager()
->getRepository('EgovCoreBundle:DemandeCCP');
$qb = $repo->createQueryBuilder('d');
$qb->select('COUNT(d)');
$qb->where('d.statut = :statut');
$qb->setParameter('statut', 'en cour');
$count = $qb->getQuery()->getSingleScalarResult();
return $this->render('@EgovAdmin/Default/backoffice.html.twig', array(
'count' => (int) $count,
));
}
所以当我这样做时
{% block notificationD %} {{ count }} {% endblock %}
我有这个例外:
Variable "count" does not exist in @EgovAdmin/Default/backoffice.html.twig
如果我像这样使用渲染控制器,则无需更改:
render(controller("EgovPosteBundle:CcpAdmin:getDemandeEnCour"))

海报表明,枝条扩展工作太多,但无论如何这是一个例子:
class MyExtension extends \Twig_Extension
{
private $em;
public function __construct($em)
{
$this->em = $em;
}
public function getFunctions()
{
return [
new \Twig_SimpleFunction('demande_count',[$this, 'getDemandeCount']),
];
}
public function getDemandeCount()
{
$repo = $this->em->getRepository('EgovCoreBundle:DemandeCCP');
$qb = $repo->createQueryBuilder('d');
$qb->select('COUNT(d)');
$qb->where('d.statut = :statut');
$qb->setParameter('statut', 'en cour');
return $qb->getQuery()->getSingleScalarResult();
}
定义为服务:
services:
demande_count:
class: MyExtension
arguments: ['@doctrine.orm.default_entity_manager']
tags: [{ name: twig.extension }]
然后在任何需要它的模板中使用它:
{{ demande_count() }}
不用大惊小怪。没有麻烦;

首先,您需要将var注入您的树枝模板
/**
* @Route("/test", name="test")
* @Template("target.html.twig")
*/
public function getDemandeEnCourAction()
{
$repo = $this ->getDoctrine()
->getManager()
->getRepository('EgovCoreBundle:DemandeCCP');
$qb = $repo->createQueryBuilder('d');
$qb->select('COUNT(d)');
$qb->where('d.statut = :statut');
$qb->setParameter('statut', 'en cour');
$count = $qb->getQuery()->getSingleScalarResult();
return array( 'count' => $count);
}
并将var访问到twig模板
{% block notificationD %} {{count}} {% endblock %}

您的控制器:
// AcmeDemoBundle:YourController:getDemandeEnCour
/**
* @Route("/test")
*/
public function getDemandeEnCourAction()
{
$repo = $this->getDoctrine()
->getManager()
->getRepository('EgovCoreBundle:DemandeCCP');
$qb = $repo->createQueryBuilder('d');
$qb->select('COUNT(d)');
$qb->where('d.statut = :statut');
$qb->setParameter('statut', 'en cour');
$count = $qb->getQuery()->getSingleScalarResult();
return $this->render('AcmeDemoBundle:YourController:count.html.twig', array(
'count' => (int) $count,
));
}
您的模板:
{% block notificationD %} {{count}} {% endblock %}
如果您只想调用特定控制器的操作并在任何树枝模板中呈现结果,您可以使用render twig功能。
您的控制器:
// AcmeDemoBundle:YourController:getDemandeEnCour
public function getDemandeEnCourAction()
{
$repo = $this->getDoctrine()
->getManager()
->getRepository('EgovCoreBundle:DemandeCCP');
$qb = $repo->createQueryBuilder('d');
$qb->select('COUNT(d)');
$qb->where('d.statut = :statut');
$qb->setParameter('statut', 'en cour');
$count = $qb->getQuery()->getSingleScalarResult();
return $this->render('AcmeDemoBundle:YourController:count.html.twig', array(
'count' => (int) $count,
));
}
AcmeDemoBundle:YourController:count.html.twig template :
{{ count }}
在其他模板中,您现在可以呈现控制器的操作:
{% block notificationD %} {{ render(controller("AcmeDemoBundle:YourController:getDemandeEnCour")) }} {% endblock %}
