学说 2 或 Where 条件

Question

我正在尝试在我的学说查询中创建 where 条件；

条件应该是；

返回所有已发送的消息，其中：

sender = A and receiver = B

或

乙;发送者 = B 接收者 = A

以下是我的查询；查询仅返回第一个条件。

public function getMessageHistory()
    { 
        $qb = $this->getEntityManager()->createQueryBuilder();

        $qb->select(array('u'))
            ->from('Messages\Entity\Messages','u')
            ->where  ('u.senderUserId = :senderId AND u.receiverUserId = :receiverId')
            ->orWhere('u.senderUserId = :receiverId AND u.receiverUserId = :senderId')
            ->setParameter('senderId',(int)$this->getUserId())
            ->setParameter('receiverId',(int)$this->getRecipientId());  

            $query = $qb->getQuery();

            return $data = $query->getArrayResult(); 
    }

提前感谢您的帮助

我会这样构建：

$qb->select(array('u'))
    ->from('Messages\Entity\Messages','u')
    ->where(
        $qb->expr()->orX(
            $qb->expr()->andX(
                $qb->expr()->eq( 'u.senderUserId', ':senderId' ),
                $qb->expr()->eq( 'u.receiverUserId', ':receiverId' )
            ),
            $qb->expr()->andX(
                $qb->expr()->eq( 'u.senderUserId', ':receiverId' ),
                $qb->expr()->eq( 'u.receiverUserId', ':senderId' )
            ),
        )
    )
    ->setParameter('senderId',(int)$this->getUserId())
    ->setParameter('receiverId',(int)$this->getRecipientId());
