Question

我有以下实体：

用户

/**
 * Users
 *
 * @ORM\Table(name="users")
 * @ORM\Entity(repositoryClass="Users\Entity\Repository\UsersRepository")
 * @Annotation\Name("user")
 * @Annotation\Hydrator("Zend\Stdlib\Hydrator\ClassMethods")
 */
class User
{   
/**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=100, nullable=false)
     * @Annotation\Filter({"name":"StringTrim"})
     * @Annotation\Validator({"name":"StringLength", "options":{"min":2, "max":100}})
     * @Annotation\Attributes({"type":"text","class":"form-control"})
     * @Annotation\Options({"label":"Full name:"})
     */
    private $name;

/**
     * @var User\Entity\UserItem
     *
     * @ORM\OneToMany(targetEntity="User\Entity\UserItem", mappedBy="user")
     * @Annotation\Exclude()
     */
    private $items;

    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     * @Annotation\Exclude()
     */
    private $id;

public function __construct()
    {
            $this->vessels = new ArrayCollection();
    }

 public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

    public function getName()
    {
        return $this->name;
    }

 public function getId()
    {
        return $this->id;
    }

public function getItems()
    {
            return $this->items
    }

    public function setItems($items)
    {
            $this->itemr = $items;
            return $this;
    }

项目

 /**
 * Items
 * @ORM\Entity
 * @ORM\Table(name="items")
 * @ORM\Entity(repositoryClass="User\Entity\Repository\ItemsRepository")
 * @Annotation\Name("item")
 * @Annotation\Hydrator("Zend\Stdlib\Hydrator\ClassMethods")
 */
  class Item
   {
    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=100, nullable=false)
     * @Annotation\Filter({"name":"StringTrim"})
     * @Annotation\Validator({"name":"StringLength", "options":{"min":2, "max":100}})
     * @Annotation\Attributes({"type":"text","class":"form-control"})
     * @Annotation\Options({"label":"Name:"})
     */
     private $name;

    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     * @Annotation\Exclude()
     */
     private $id;

最后实体保持这两者之间的关系 UserItem

 /**
  * UserItem
  *
  * @ORM\Table(name="users_items")
  * @ORM\Entity(repositoryClass="User\Entity\Repository\UserItemsRepository")
  * @Annotation\Name("user_item")
  * @Annotation\Hydrator("Zend\Stdlib\Hydrator\ClassMethods")
  */
 class UserItem{    
     /**
      * @var Users\Entity\User
      *
      * @ORM\ManyToOne(targetEntity="Users\Entity\User", inversedBy="items")
      * @ORM\JoinColumn(name="user_id", referencedColumnName="id")
      * @Annotation\Exclude()
      */
     private $user;

     /**
      * @var User\Entity\Item
      *
      * @ORM\ManyToOne(targetEntity="User\Entity\Item", inversedBy="users")
      * @ORM\JoinColumn(name="item_id", referencedColumnName="id")
      * @Annotation\Type("DoctrineModule\Form\Element\ObjectSelect")
      */
     private $item;

     /**
      * @var integer
      *
      * @ORM\Column(name="id", type="integer")
      * @ORM\Id
      * @ORM\GeneratedValue(strategy="AUTO")
      * @Annotation\Exclude()
      */
     private $id;

通过这些实体，我可以创建和编辑用户和项目。表单由注释生成。我的问题是我如何生成表单给用户分配项目。优选地，作为具有多个选择的选择字段。提交原则后应该保存关系。

我写了这个表单来表示要选择的项目：

class ItemsForm extends Form
{
    public function __construct($entityManager, $name = null)
    {
        parent::__construct('items');
        $this->setAttribute('method', 'post');
        $this->add(array(
            'type' => 'DoctrineModule\Form\Element\ObjectSelect',
            'name' => 'items',
            'attributes' => array(
                'id' => 'selectItems',
                'multiple' => true,
                'data-placeholder' => 'Items'
            ),
            'options' => array(
                'object_manager' => $entityManager,
                'target_class' => 'User\Entity\Item',
                'property' => 'name',
                ),
            )
        );        
    }
}

现在我不知道如何预选用户已分配的项目。

在值中的选择字段中，您必须具有来自项目的ID。提交后你可以做类似的事情

foreach($post['items'] as $itemId)
{
    $userItem = new UserItem();
    $userItem->user = $this->getEntityManager()->getReference('User', $userId);
    $userItem->item = $this->getEntityManager()->getReference('Item', $itemId);
    $this->getEntityManager()->save($userItem);
}
