Question

您好我的捆绑包中创建了以下帮助程序：

埃杜/ AccountBundle /服务/ Helper.php

namespace Edu\AccountBundle\Service;
use Doctrine\ODM\MongoDB\DocumentManager;
use Symfony\Bundle\FrameworkBundle\Routing\Router;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\Form\Form;
use Edu\AccountBundle\CommonFunctions\CommonFunctions;

class Helper{

private $session;
private $router;
private $documentManager;
private $commonFunctions;

/*
 * Class:Constructor
 * @DESC:its a very first method which always called whenever this call going to be instantiate
 * @param : @session,@route,@db
 * @sunilrawat@indivar.com
 * @03-06-2016
 */
public function __construct(Session $session, Router $router, DocumentManager $dm)
{
    $this->session = $session;
    $this->router = $router;
    $this->dm = $dm;
    $this->commonFunctions = new CommonFunctions();
}

/*
 * Class:checkFinancialYearLockPeriod
 * @DESC:check a particular date on which accounts Financial Year data will be Locked So that user can not make any modifications after that
 * @param : @db
 * @sunilrawat@indivar.com
 * @03-06-2016
 */
public function checkFinancialYearLockPeriod($dm){
    $currentYearIs = $this->commonFunctions()->checkFinancialYear($this->dm);
    $exploadsCurrentYear = explode("-",$currentYearIs);
    $currentFinancialYearTo = "31-03-".$exploadsCurrentYear[1];
    return $effectiveDate = date('d-m-Y', strtotime("+63 days", strtotime($currentFinancialYearTo)));        
}
}

 //My services.xml code is as following:
<service id="edu.account.helper" class="Edu\AccountBundle\Service\Helper">
            <argument type="service" id="session"/>
            <argument type="service" id="router"/>
            <argument type="service" id="doctrine_mongodb.odm.document_manager"/>
            <tag name="twig.helper" />
        </service>     
 //So now I want to call it on Twig directly. So I am calking it as   follows:
 {{ edu.account.helper.checkFinancialYearLockPeriod() }}

但它没有像抛出以下错误一样工作：＆＃34;变量＆＃34; edu＆＃34;不存在＆＃34;。

请帮助解决此问题，提前致谢：

Helper in Symfony2 not able to call on Twig 是完全正确的。

没有名为＆＃34; twig.helper＆＃34;的标签。只有一个名为＆＃34; twig.extension＆＃34;。如果要使用它，则应扩展\ Twig_Extension。请参阅http://symfony.com/doc/current/cookbook/templating/twig_extension.html。

但在您的情况下，您需要执行以下操作：

#app/config/config.yml
twig:
    globals:
        edu_account_helper: "@edu.account.helper" #key is name in twig, value is reference to your service

这意味着在Twig-Scope中，它被称为＆＃34; edu_account_helper＆＃34;。蛇套管。

{{ edu_account_helper.checkFinancialYearLockPeriod() }}

Symfony2中的助手无法呼叫Twig
