Question

我实际上是在Symfony2中开发一个应用程序。我已经建立了一个具有不同角色的认证工作系统，根据官方文档的建议设置我的表格结构：http://symfony.com/doc/current/cookbook/security/entity_provider.html

我有两个页面，使用表单允许我创建新用户并编辑现有用户，现在我需要实现一个表单字段（选项）来选择与用户关联的角色。 无论如何，我发现了一些困难：＃/ p>

这是我对\ Entity \ User.php

在DB中报告如下：

----------------------------------------------------------------------
...| ...      | ...      | ...    | ...  | ...          | ...

这是我对\ Entity \ Role.php

的ORM定义

<?php

namespace Acme\MyBundle\Entity;

use Symfony\Component\Security\Core\Role\RoleInterface;

use Doctrine\Common\Collections\ArrayCollection;

/**

class Role implements RoleInterface

    // Definizione campi

    /**

     */
    private $id;

    /**

     */
    private $users;

    // Funzioni di servizio

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

    // Funzioni di tipo Get

    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Get name
     *
     * @return string
     */
    public function getName()
    {
        return $this->name;
    }

    /**
     * @see RoleInterface
     */
    public function getRole()
    {
        return $this->role;
    }

    /**
     * Set role
     *
     * @param string $role
     * @return Role
     */
    public function setRole($role)
    {
        $this->role = $role;
        return $this;
    }

    /**
     * Set name
     *
     * @param string $name

     */
    public function setName($name)
    {
        $this->name = $name;
        return $this;
    }
}

在DB中报告如下：

ID | NAME | ROLE
----------------
...| ...  | ...

此外，ORM命令自动生成（无需在我的Entity文件夹中编写自定义类），表user_roles为我管理User和Roles之间的关系。

ID_USER | ID_ROLE
-----------------
...     | ...

这是我的表格：

<?php

use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Doctrine\ORM\EntityRepository;

class UserType extends AbstractType
{

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array('data_class' => 'Acme\MyBundle\Entity\User', 'Acme\MyBundle\Entity\Role'));
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        // Crezione del form
        $builder->add('username', 'text', array('label' => 'Username: ', 'required' => false));
        $builder->add('password', 'repeated', array('first_name' => 'password', 'second_name' => 'confirm', 'type' => 'password'));
        $builder->add('attivo', 'checkbox', array('label' => 'Attivo', 'required'  => false));
        $builder->add('idTipoVisita', 'choice', array('choices' => array('1' => 'Fisiatra', '2' => 'Genetista'), 'required'  => false));
// $builder->add( ***I NEED TO INSERT HERE THE DROPODOWN FIELD TO SELECT THE ROLE*** );
            $builder->add('save', 'submit');
            $builder->add('annulla', 'submit');
        }

        public function getName()
        {
            return 'user';
        }
    }

这是我的控制器：

1）我的表单映射到User.php实体上，我不知道如何添加一个引用另一个实体（Role.php）的表单字段，与默认的'data_class'不同。

2）另一个问题是我需要提取一个字符串orray（角色的人类可重复名称）来显示我的Dropdown上的选项，但是我需要在DB中插入相关的id而不是串即可。我该怎么做？我是否应该这样做：http://symfony.com/doc/current/cookbook/form/data_transformers.html？

3）我认为表单字段实例（下拉列表）不允许我在我的数据库（关联ID_USER和ID_ROLE）中自动插入一个包含2个字段的新记录。使这成为可能的最佳方法是什么？我想我需要从我的下拉字段中提取值并在控制器中构建一个查询，但是我该怎么做呢？

非常感谢您的建议，问候。

在UserType：

中

// ...
$builder
   ->add('userroles', 'entity', array(
      'class' => 'AcmeMyBundle:Role',
      'property' => 'name'
      'multiple'  => true));
// ...

在User实体中：

// ...
public function setUserroles($roles)
{
   $this->roles = $roles;

   return $this;
}

public function getUserroles()
{
   return $this->roles;
}
// ...

在你的php模板中：

<?php if ($view['form']->errors($form['userroles'])): ?>
   <div class="error">
       <?php echo $view['form']->errors($form['userroles']) ?>
   </div>
<?php endif; ?>

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

<强>更新在User.php：

中

/**
 * @var \Doctrine\Common\Collections\Collection
 *
 * @ORM\ManyToMany(targetEntity="Role", inversedBy="users")
 * @ORM\JoinTable(name="User_Role",
 *   joinColumns={
 *     @ORM\JoinColumn(name="user_id", referencedColumnName="id")
 *   },
 *   inverseJoinColumns={
 *     @ORM\JoinColumn(name="role_id", referencedColumnName="id")
 *   }
 * )
 */
private $roles;
