Symfony2 - 联系FormBuilder。变量形式不存在于树枝模板中。一个网站页面 [英] Symfony2 - contact FormBuilder. Variable form does not exist in twig template. One site page
问题描述
当我尝试在OneSitePage网站上制作一个简单的联系表单时,我坐在symfony2 FormBuilder下三个小时。我会注意到我主要是前端,但我需要通过跨越symfony2的Swiftmailer发送电子邮件。请不要问,为什么我使用的是symfony:)
问题:我的主页有渲染表单问题,因为Symfony说,就像在主题中一样:
变量表单在YodaHomeBundle :: layout.html.twig中不存在...
,它指向行我正在使用树枝形式(在TWIG部分中附上)
好的,那是介绍。下面我介绍PHP类的控制器和ContactType类,下面还附加了layout.html.twig文件。
首先来控制器,我有两个动作,索引和联系。
namespace Yoda\HomeBundle\Controller;
使用Symfony \ Bundle \ FrameworkBundle \Controller\Controller;
使用Symfony \Component\HttpFoundation\Request;
使用Sensio \ Bundle \FrameworkExtraBundle\Configuration\Template;
使用Symfony \Component\Routing\Annotation\Route;
使用Yoda \UserBundle \Entity \User;
使用Yoda \ HomeBundle \ Form \ContactType;
使用Symfony \Component\Form\FormInterface;
class HomeController extends Controller {
$ b $ / **
* @Route(/ home,name =homePage)
* @Template()
*
* /
public function indexAction(){
return $ this-> render('YodaHomeBundle :: layout.html 。枝条');
$ b public function contactAction(Request $ request)
{
$ form = $ this-> createForm(new ContactType ());
$ adress ='grzegorz.developer@gmail.com';
if($ request-> isMethod('POST'))
{
$ form-> submit($ request-> request-> get($形状配合>的getName()));
if($ form-> isValid())
{
$ message = \Swift_Message :: newInstance()
- > setSubject($ form - > get('subject') - > getData())
- > setFrom($ form-> get('email') - > getData())
- > setTo($ adress)
- > setBody(
$ this-> renderView('@ YodaHome / mail / contact.html.twig',
array(
'ip '=> $ request-> getClientIp(),
'name'=> $ form-> get('name') - > getData(),
'message'=> ; $ form-> get('message') - > getData()
))
);
$ this-> get('mailer') - > send($ message);
$ request-> getSession() - > getFlashBag() - > add('成功,您的邮件已发送!谢谢,我会尽快回复您\\'可能!');
返回$ this->重定向($ this-> generateUrl('homePage'));
$ b return array(
'form'=> $ form-> createView()
);
}
}
class ContactType extends AbstractType
{
public function buildForm(FormBuilderInterface $ builder,array $ options)
{
$ builder
- > add('name','text',array(
'attr'= >数组(
'placeholder'=&';'What's your name?',
'length'=>'。{2,}'
)
)
- > add('email','email',array(
'attr'=> array(
'placeholder'=>'所以我可以写回来(
)
))
- > add('subject','text',array(
'attr'=> array(
' placeholder'=>'消息的主题',
'patt ($'$'$&'; $'$'$'$'$'$' >数组(
'cols'=>'90',
'row'=>'10',
'placeholder'=>'将您的消息广告给我... '
)
));
public function setDefaultOptions(OptionsResolverInterface $ resolver)
{
$ collectionConstraint = new Collection(array(
'name'=> array(
new NotBlank(array('message'=&';'你忘了名字')),
new Length(array('min'=> 2))
),
'email'=> array(
new NotBlank(array('message'=&';'Email should not be blank。')),
new Email(array('message' =)'无效的电子邮件地址'))
),
'subject'=>数组(
new NotBlank(array('message'=&''主题不应该为空')),
new Length(array('min'=> 3))
),
'message'=>数组(
new NotBlank(array( 'message'=>'消息不应该为空')),
新的长度(数组('min'=> 5))
)
));
$ resolver-> setDefaults(array(
'constraints'=> $ collectionConstraint
));
}
public function getName()
{
return'homePage';
}
以及上次路线和TWIG:
mail_create:
路径:/ homePage
默认值:{_controller:YodaHomeBundle:Home:contact}
requirements: _method:post}
[...]
{{form_start(form)}}
{{form_widget(form))}
{{form_end(form)}}
< / form>
[...]
请支持,无论何地, ,并且我拥有一个页面上的所有内容。所有提示,欢迎您提出意见!

你需要在layout twig上渲染你的表单:
public function indexAction(){
$ form = $ this- > createForm(new ContactType());
return $ this-> render('YodaHomeBundle :: layout.html.twig',array('form'=> $ form-> createView());
}
或者你可以拆分布局,一个控制器是一个布局:
Controller:
class HomeController extends Controller {
/ **
* @Route(/ home,name =homePage)
* @Template()
*
* /
public function indexAction(){
return $ this-> render('YodaHomeBundle :: layout.html.twig');
}
public function contactAction(Request $ request)
{
$ form = $ this-> createForm(new ContactType());
//做你的代码
return array(
'YodaHomeBundle :: contactlayout.html.twig',
array('form'=> $ form-> createView());
}
}
以及TWIG:
布局。 html.twig:
[..]
< div> { {render(controller('YodaHomeBundle:Home:contact'))}}< / div>
[..]
contactlayout.html.twig:
[..]
{{form_start(form)}}
{{form_widget(form))}
{{form_end(form)}}
< / form>
[..]
I am sitting three hours under symfony2 FormBuilder, when I try to make a simple contact form, on my OneSitePage website. I will notice that I am mostly frontend, but I need send emails via Swiftmailer across symfony2. Please do not ask, why I am using symfony:)
PROBLEM: I have issue with render form on my homePage, because Symfony says, like in subject:
"Variable "form" does not exist in YodaHomeBundle::layout.html.twig..." and it point for line where I am useing twig form(attached below in TWIG section)
Ok, that was introduction. Below I present PHP class of controller and ContactType class, also below I had attached layout.html.twig file.
First comes controller, where I have two actions, index and contact.
namespace Yoda\HomeBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Symfony\Component\Routing\Annotation\Route;
use Yoda\UserBundle\Entity\User;
use Yoda\HomeBundle\Form\ContactType;
use Symfony\Component\Form\FormInterface;
class HomeController extends Controller{
/**
* @Route("/home", name="homePage")
* @Template()
*
*/
public function indexAction(){
return $this->render('YodaHomeBundle::layout.html.twig');
}
public function contactAction(Request $request)
{
$form = $this->createForm(new ContactType());
$adress = 'grzegorz.developer@gmail.com';
if($request->isMethod('POST'))
{
$form->submit($request->request->get($form->getName()));
if($form->isValid())
{
$message = \Swift_Message::newInstance()
->setSubject($form->get('subject')->getData())
->setFrom($form->get('email')->getData())
->setTo($adress)
->setBody(
$this->renderView('@YodaHome/mail/contact.html.twig',
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 mail has been send! Thank you, I will back to you, as soon as it\'s possible!');
return $this->redirect($this->generateUrl('homePage'));
}
}
return array(
'form' => $form->createView()
);
}
}
now builder, Simple builder which is used on many tuts.
class ContactType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name', 'text', array(
'attr' => array(
'placeholder' => 'What\'s your name?',
'length' => '.{2,}'
)
))
->add('email', 'email', array(
'attr' => array(
'placeholder' => 'So I can write back to you'
)
))
->add('subject', 'text', array(
'attr' => array(
'placeholder' => 'Subject of your message',
'pattern' => '.{5,}'
)
))
->add('message', 'text', array(
'attr' => array(
'cols' => '90',
'row' => '10',
'placeholder' => 'And ad your message to me...'
)
));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$collectionConstraint = new Collection(array(
'name' => array(
new NotBlank(array('message' => 'You forgot about the Name.')),
new Length(array('min' => 2))
),
'email' => array(
new NotBlank(array('message' => 'Email should not be blank.')),
new Email(array('message' => 'Invalid email address.'))
),
'subject' => array(
new NotBlank(array('message' => 'Subject should not be blank.')),
new Length(array('min' => 3))
),
'message' => array(
new NotBlank(array('message' => 'Message should not be blank.')),
new Length(array('min' => 5))
)
));
$resolver->setDefaults(array(
'constraints' => $collectionConstraint
));
}
public function getName()
{
return 'homePage';
}
And for last place routing and TWIG:
mail_create:
path: /homePage
defaults: { _controller: "YodaHomeBundle:Home:contact" }
requirements: { _method: post }
[...]
<form action="{{ path('mail_create') }}" method="post">
{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}
</form>
[...]
Please for support, everywhere are solutions for different routes for contact, and I have everything on one page. All hints are welcome, please for comments!

you need render your form on layout twig by:
public function indexAction(){
$form = $this->createForm(new ContactType());
return $this->render('YodaHomeBundle::layout.html.twig',array('form' => $form->createView());
}
Or you can split layout, one controller is one layout:
Controller:
class HomeController extends Controller{
/**
* @Route("/home", name="homePage")
* @Template()
*
*/
public function indexAction(){
return $this->render('YodaHomeBundle::layout.html.twig');
}
public function contactAction(Request $request)
{
$form = $this->createForm(new ContactType());
// do your code
return array(
'YodaHomeBundle::contactlayout.html.twig',
array('form' => $form->createView());
}
}
And for TWIG: layout.html.twig:
[..]
<div>{{ render(controller('YodaHomeBundle:Home:contact')) }}</div>
[..]
contactlayout.html.twig:
[..]
<form action="{{ path('mail_create') }}" method="post">
{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}
</form>
[..]
