Question

我想在查询构建器中添加orWhere条件。 params将来自阵列。但我不知道如何添加等于计数数组元素的orWhere语句的数量。这是一些代码：

 public function selectRelatedTrips($assoc)
{
    $params = array('k' => 'Kiev');
    $query = $this
        ->getEntityManager()
        ->createQueryBuilder()
        ->select('t')
        ->from('VputiTripBundle:Trip', 't')
        ->where('t.startCity = :k');

    foreach ($assoc as $k => $v) {
         //            $query->orWhere('t.startCity = ' . $v);
        $query->where('t.startCity = :param' . $k);
        $params['param' . $k] = $v;
    }

    return $query->setParameters($params)
        ->setMaxResults(20)
        ->orderBy('t.id', 'desc')
        ->getQuery()
        ->getResult();
}

有人可以帮帮我吗？

Answer 1

您可以使用in()功能：

class AcmeRepository extends EntityRepository
{
    public function selectRelatedTrips($assoc)
    {
        $qb = $this->createQueryBuilder('e');

        $qb = $qb
            ->where(
                $qb->expr()->in('e.field2', array_keys($assoc))
            );

        return($qb->getQuery()->getResult());
    }
}

请参阅How to use WHERE IN with Doctrine 2和Doctrine2 Query Builder以获取参考资料。

Answer 2

尝试根据您的数组动态构建查询：

$params = array('param1' => 123);

$query = $this
     ->createQueryBuilder('e')
     ->select('e')
     ->where('e.field = :param1')

foreach ($assoc as $k => $v) {
    $query->orWhere('e.field2 = :param'.$k);
    $params['param'.$k] = $v;
}

$query->setParameters($params);

EntityRepository Symfony2中的多个条件
