Question

我想制作一个表单，其中我可以使用元素来填充两个实体。我怎样才能做到这一点？其中一个对象映射到另一个对象。例如，我有这样的事情：

表用户：

id | login | password

表user_email：

id | user_id | email

user_email可以有多行映射到用户 - 用户可以拥有多个电子邮件。但是 - 当我添加用户的第一次出现时，我必须收到他的第一封电子邮件。

我知道如何映射实体，但是我从ZF2表格填充对象时遇到问题。

有谁能建议我该怎么做？我试图制作两个字段集，但我不能将对象绑定到fieldset。如果这是解决方案如何绑定对象形成哪个有两个文件集？每个fieldset都映射了doctrine2 hydrator，但是当我试图将一个实体绑定到form（而不是我不能做的fieldset）时，我有错误信息：

Zend\Stdlib\Hydrator\ArraySerializable::extract expects the provided object to implement getArrayCopy()

在我的例子之前，我必须解释我想要实现的目标。我有一个桌面摄像头 - 其中包含有关流媒体摄像头的链接和其他一些信息。第二个表：cameras_desc包含对不同语言的摄像机的描述。在我的CMS中，我想添加两行：一行在相机中，第二行在cmaeras_desc中以一种形式添加。 cameras_desc将首先使用波兰语进行翻译（这将是CMS的默认语言）。你可以看到摄像机和cameras_desc映射到其他一些entites（带检查点的摄像机和带语言的cameras_desc）。但那不是重点。我想要实现的是通过一个表单在两个表中填充两行。 cameras_desc中的lang由PHP代码设置，但是checkpoint由用户在表单中由select元素设置。一切都在下面的代码中工作，但它并不诚实。

这是我的代码：

第一个实体：

namespace Granica\Entity;

use Doctrine\ORM\Mapping as ORM;

/**

    }

    }

    /**

    public function setCheckpoint(\Granica\Entity\Checkpoints $checkpoint = null)
    {
        $this->checkpoint = $checkpoint;

        return $this;
    }

    /**

     */
    public function getCheckpoint()

        return $this->checkpoint;
    }
}

    private $id;

    }

    /**

     */
    public function getCamera()

        return $this->camera;

}

Fieldset（适用于camera_desc）：

namespace Granica\Form;

use Zend\Form\Fieldset;

use DoctrineModule\Persistence\ObjectManagerAwareInterface;
use Doctrine\Common\Persistence\ObjectManager;
use DoctrineModule\Stdlib\Hydrator\DoctrineObject as DoctrineHydrator;
use DoctrineORMModule\Stdlib\Hydrator\DoctrineEntity;

use Granica\Entity\Languages;

class CameraDescFieldset extends Fieldset implements ObjectManagerAwareInterface
{
    protected $objectManager;
    public function __construct(ObjectManager $objectManager)
    {
        parent::__construct('camera_desc');
        $this->setObjectManager($objectManager);
        $this->setHydrator(new DoctrineHydrator($this->getObjectManager(),'Granica\Entity\CameraDesc'));        

        $this->add(array(
            'name' => 'description',
            'attributes' => array(
                'type'  => 'text',
                'placeholder' => 'Opis',
                'required' => 'true',
            ),
            'options' => array(
                'label' => 'Opis kamery',
            ),
        ));

    }

    // implementacja interfajsu objectmanager
    public function setObjectManager(ObjectManager $objectManager)
    {
        $this->objectManager = $objectManager;
        return $this;
    }

    public function getObjectManager()
    {
        return $this->objectManager;
    }

}

表格（相机）：

use Zend\Form\Form;

use DoctrineModule\Persistence\ObjectManagerAwareInterface;
use Doctrine\Common\Persistence\ObjectManager;

use Granica\Form\CameraDescFieldset;

class AddCameraForm extends Form implements ObjectManagerAwareInterface
{
    protected $objectManager;
    public function __construct(ObjectManager $objectManager)
    {       
        parent::__construct('checkpoint');
        $this->setObjectManager($objectManager);

        // tworzenie formularza
        $this->setAttribute('method', 'post');

        $this->add(array(
            'name'    => 'checkpoint',
            'type'    => 'DoctrineModule\Form\Element\ObjectSelect',
            'options' => array(
                'label'          => 'Punkt graniczny',
                'object_manager' => $this->getObjectManager(),
                'target_class'   => 'Granica\Entity\Checkpoints',
                'property'       => 'name',
                'empty_option'   => '--- wybierz przejście ---'
            ),
        ));

        $this->add(array(
            'name' => 'link',
            'attributes' => array(
                'type'  => 'text',
                'placeholder' => 'Link',
                'required' => 'true',
            ),
            'options' => array(
                'label' => 'Adres URL kamery',
            ),
        ));

        $this->add(array(
            'type' => 'Zend\Form\Element\Select',
            'name' => 'direction',
            'attributes' => array(
                'required' => 'true',
            ),
            'options' => array(
                'label' => 'Kierunek',
                'empty_option' => '--- wybierz kierunek ---',
                'value_options' => array(
                    'from' => 'FROM: Wyjazd z Polski',
                    'to' =>   'TO:   Wjazd do Polski',
                ),
            )
        ));               

        $this->add(new CameraDescFieldset($this->getObjectManager()));

        $this->add(array(
            'name' => 'submit',
            'attributes' => array(
                'type'  => 'submit',
                'value' => 'Zapisz',
                'id' => 'submitbutton',
            ),
        )); 
    }

    // implementacja interfajsu objectmanager
    public function setObjectManager(ObjectManager $objectManager)
    {
        $this->objectManager = $objectManager;
        return $this;
    }

    public function getObjectManager()
    {
        return $this->objectManager;
    }       

}

添加控制器：

public function addAction()
{
    $camera = new Cameras();
    $cameraDesc = new CameraDesc();
    $lang = $this->getEntityManager()->getRepository('Granica\Entity\Languages')->find('pl');

    $form = new AddCameraForm($this->getEntityManager());
    $cameraDescFieldset = new CameraDescFieldset($this->getEntityManager());

    $form->setHydrator(new DoctrineHydrator($this->getEntityManager(),'Granica\Entity\Cameras'));

    $form->bind($camera);

    $request = $this->getRequest();
    if ($request->isPost()) {
        $form->setData($request->getPost());
        if ($form->isValid()) {
            $data = $form->getData(); 
            $cameraDesc->setLang($lang);
            $cameraDesc->setDescription($request->getPost()['camera_desc']['description']);

            $this->getEntityManager()->persist($camera);            

            $cameraDesc->setCamera($camera);            

            $this->getEntityManager()->persist($cameraDesc);            
            $this->getEntityManager()->flush();

            return $this->redirect()->toRoute('cameras');
        }
    }

    return new ViewModel(array('form' => $form));
}

正如你所看到的，我已经设法克服了我的问题 - 我已经使用我从帖子中获得的数据填充了camera_desc。这项工作，但不是最好的解决方案 - 例如过滤器不适用于cameraDesc descrition。
