这是 modiffilmAction() 的一部分，用于编辑电影名称和演员。电影和演员之间存在多对多关联。只有标题填写表格。如果此代码可以根据您的要求工作，您能告诉我如何填写表格吗？或者这段代码有什么问题。我没有找到任何例子。

    $em = $this->getEntityManager();

    $qb = $em->createQueryBuilder();

    $qb ->select(array('f','a'))
        ->from('Cine\Entity\Films', 'f')
        ->where($qb->expr()->eq('f.id', '?1'))
        ->innerJoin('f.actors', 'a')
        ->setParameter(1, $id);
    $query = $qb->getQuery();
    $film = $query->getResult();

    $form = new FilmForm($em);
    $form->bind($film);
    ...

如果我替换查询， $film = $em->find('Cine\Entity\Films', $id); 在关联中使用 fetch="eager" ，结果相同：没有绑定数据。

我想我还没有理解一些非常简单的东西，但我是 zf2 和学说 2 的新手......谢谢你的帮助

尝试这样的事情；

控制器动作：

public function editAction()
{
    $film = new Film;

    if ($this->params('id') > 0) {
        $film = $this->getEntityManager()->getRepository('Cine\Entity\Film')->find($this->params('id'));
    }

    $form = new FilmForm($this->getEntityManager());
    $form->setHydrator(new DoctrineEntity($this->getEntityManager(),'Cine\Entity\Film'));
    $form->bind($film);

    $request = $this->getRequest();
    if ($request->isPost()) {
        $form->setInputFilter($film->getInputFilter());
        $form->setData($request->getPost());

        if ($form->isValid()) {
            $em = $this->getEntityManager();
            $em->persist($film);
            $em->flush();

            $this->flashMessenger()->addSuccessMessage('Film Saved');

            return $this->redirect()->toRoute('cine/default', array('controller' => 'film','action' =>  'index'));
        }
    }

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

形式：

<?php
namespace Cine\Form;

use Doctrine\ORM\EntityManager;
use Zend\Form\Form;
use Zend\Form\Element;

class FilmForm extends Form
{
public function __construct(EntityManager $em)
{
    parent::__construct('film');

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

    $this->add(array(
        'name' => 'id',
        'attributes' => array(
            'type'  => 'hidden',
        ),
    ));

    $this->add(array(
        'name' => 'title',
        'type'  => 'text',
        'options' => array('label' => 'Film Title'),
        'attributes' => array(
            'class' => 'input-xxlarge'
        )
    ));


    $this->add(array(
        'name' => 'actors',
        'type' => 'DoctrineModule\Form\Element\ObjectSelect',
        'options' => array(
            'label' => 'Actors',
            'empty_option'    => 'Select Actors',
            'object_manager' => $em,
            'target_class' => 'Cine\Entity\Actor',
            'property' => 'name'
        ),
        'attributes' => array(
            'multiple' => 'multiple',
            'required' => false,
            'class' => 'chosen'
        )
    ));

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

看法：

<?php

$title = 'Edit Film';
$this->headTitle($title);
?>
<h1><?php echo $this->escapeHtml($title); ?></h1>

<?php   $form->setAttribute('action', $this->url('cine/default', array('controller' => 'film', 'action' => 'edit', 'id' => $film->getId())));
$form->setAttribute('class', 'form-horizontal');

$form->prepare();


echo $this->form()->openTag($form);
echo $this->formHidden($form->get('id'));

//Film Title
echo $this->formRow($form->get('title'));

echo $this->formRow($form->get('actors'));

echo $this->formSubmit($form->get('submit'));
echo $this->form()->closeTag();


?>
