ContactType.php

    public function getName()

        return 'contact';
    }

?>

控制器

<?php

namespace Aleksandar\IntelMarketingBundle\Controller;
use Aleksandar\IntelMarketingBundle\Form\Type\ContactType;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;


class DefaultController extends Controller
{

/**
 * @Route("contact", _name="contact")
 * @Template()
 */      

         public function contactAction()
    {
    return $this->render('AleksandarIntelMarketingBundle::contact.html.php');

    $form = $this->createForm(new ContactType());

    if ($request->isMethod('POST')) {
        $form->bind($request);

        if ($form->isValid()) {
            $message = \Swift_Message::newInstance()
                ->setSubject($form->get('subject')->getData())
                ->setFrom($form->get('email')->getData())
                ->setTo('info@intelmarketing.es')
                ->setBody(
                    $this->renderView(
                        'AleksandarIntelMarketingBundle::contact.html.php',
                        array(
                            'ip' => $request->getClientIp(),
                            'name' => $form->get('name')->getData(),
                            'message' => $form->get('message')->getData()
                        )
                    )
                );

            $this->get('mailer')->send($message);

            $request->getSession()->getFlashBag()->add('success', 'Your email has been sent! Thanks!');

            return $this->redirect($this->generateUrl('contact'));
        }
    }

    return array(
        'form' => $form->createView()
    );

    }


}

路由

aleksandar_intel_marketing_contactpage:
    pattern:  /contact
    defaults: { _controller: AleksandarIntelMarketingBundle:Default:contact }

以及view文件夹

上的contact.html.php

<?php echo $view['form']->form($form) ?>

现在，当我在contact.html.php中添加上面的代码时，我得到了结果

 Notice: Undefined variable: form in C:\wamp\www\symfony\src\Aleksandar\IntelMarketingBundle\Resources\views\contact.html.php line 1
500 Internal Server Error - ContextErrorException

我的观点代码

<!-- app/Resources/views/contact.html.php -->
<!DOCTYPE html>
<html>
    <head><?php echo $view->render('AleksandarIntelMarketingBundle:template:head.html.php') ?></head>
<body>
    <div class="wrapper">
        <div id="header"><?php echo $view->render('AleksandarIntelMarketingBundle:template:header.html.php') ?></div>
            <div id="leftside"><?php echo $view->render('AleksandarIntelMarketingBundle:template:leftside.html.php') ?></div>
            <div id="rightside"><?php echo $view->render('AleksandarIntelMarketingBundle:template:rightside.html.php') ?>
                <div class="container">



                    </div>
                    <script type="text/javascript">
                         $(document).ready(function () {
                             if (!$.browser.webkit) {
                                $('.container').jScrollPane();
                                                    }
                                                         });
                    </script>
            <div id="clear"></div>
            </div>
    <div id="footer">
    <?php echo $view->render('AleksandarIntelMarketingBundle:template:footer.html.php') ?>
    </div>
        </div>
</body>
</html>

您需要将form添加到此块：

$this->renderView('AleksandarIntelMarketingBundle::contact.html.php', array(
    'ip'      => $request->getClientIp(),
    'name'    => $form->get('name')->getData(),
    'message' => $form->get('message')->getData(),
    'form'    => $form->createView(),
));

我也注意到你有

return $this->render('AleksandarIntelMarketingBundle::contact.html.php');

作为contactAction方法中的第一行。应该删除它，因为你的代码不会超过该行，它只是返回视图。
