Question

我是symfony的初学者，我必须使用收集表格建立一个网站来预订节目门票。

界面很简单，用户选择他想要的门票数量，然后显示尽可能多的表格原型（姓名和姓氏输入）作为所需的门票。这部分适合我。

每次提交=新预订

我有2张桌子＆＃34;预订＆＃34;和＆＃34;票＆＃34;在mysql中，我希望在提交表单后获得此渲染：

表格预订：

预订ID =＆＃34; 1＆＃34;

预订ID =＆＃34; 2＆＃34;

表坯：

方坯ID =＆＃34; 1＆＃34; name =＆＃34; thomas＆＃34;，surname =＆＃34; good＆＃34;，reservation_id =＆＃34; 1＆＃34;

方坯ID =＆＃34; 2＆＃34; name =＆＃34; laura＆＃34;，surname =＆＃34; senior＆＃34;，reservation_id =＆＃34; 1＆＃34;

方坯ID =＆＃34; 3＆＃34; name =＆＃34; pierre＆＃34;，surname =＆＃34; martin＆＃34;，reservation_id =＆＃34; 2＆＃34;

问题是我得到了这个结果：

方坯ID =＆＃34; 1＆＃34; name =＆＃34; thomas＆＃34;，surname =＆＃34; good＆＃34;，reservation_id =＆＃34; Null＆＃34;

方坯ID =＆＃34; 2＆＃34; name =＆＃34; laura＆＃34;，surname =＆＃34; senior＆＃34;，reservation_id =＆＃34; Null＆＃34;

这是我的实体：

你的命名有点困惑......

我建议：

class Billet
{
/**
 * @var int
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @ORM\ManyToOne(targetEntity="Reservation", inversedBy="billets")
 * @ORM\JoinColumn(name="reservation_id", referencedColumnName="id")
 */
protected $reservation;

/**
 * @var string
 *
 * @ORM\Column(name="prenom", type="string", length=255)
 */
private $prenom;

/**
 * @var string
 *
 * @ORM\Column(name="nom", type="string", length=255)
 */
private $nom;


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

/**
 * Set prenom
 *
 * @param string $prenom
 * @return Billet
 */
public function setPrenom($prenom)
{
    $this->prenom = $prenom;

    return $this;
}

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

/**
 * Set nom
 *
 * @param string $nom
 * @return Billet
 */
public function setNom($nom)
{
    $this->nom = $nom;

    return $this;
}

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

public function setReservation(Reservation $reservation)
{
    $this->reservation = $reservation;

    return $this;
}

public function getReservation()
{
    return $this->reservation;
}
}

Reservation实体

/**
 * Reservation
 *
 * @ORM\Table(name="reservations")
 * @ORM\Entity(repositoryClass="Louvre\PagesBundle\Repository\ReservationsRepository")
 */
class Reservation
{
/**
 * @var int
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;


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


/**
 * @ORM\OneToMany(targetEntity="Billet", mappedBy="reservations", cascade={"persist","remove"})
 */
protected $billets;


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

public function getBillets()
{
    return $this->billets;
}

public function addBillet(Billet $billet)
{
    if (!$this->billets->contains($billet))
    {
        $this->billets->add($billet);
        $billet->setReservation($this);
    }

    return $this;
}

public function removeBillet(Billet $billet)
{
    // you can implement for collection
}

public function setBillets($billets)
{
    $this->billets = new ArrayCollection();

    foreach ($billets as $billet)
    {
        $this->addBillet($billet)
    }

    return $this;
}

}

Doctrine加入表以获取相同的ID
