为什么 Doctrine Query 会抛出 "Too many parameters" QueryException

Question

这是在控制器中

$candidats = $repository->findList(
$data["recherche_candidat"]["diplomes"],
$data["recherche_candidat"]["categories"]);

这在存储库中

public function findList($diplomes,$categories,)
{
    $qb=$this->createQueryBuilder('c');

    if($categories!=null){
        $qb->andWhere('c.categorie IN (:value)')
            ->setParameter(':value', $categories);
    }

    if($diplomes!=null) {
        $qb->andWhere('c.diplome IN (:value)')
            ->setParameter(':value', $diplomes);
    }

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

问题是当 diplomes 和 categories 不为空时我看到一个错误：

Too many parameters: the query defines 1 parameters and you bound 2

With one null its work; for example diplomes==null and categories!=null it work without error

您为两个参数指定了相同的名称，因此 Doctrine 无法区分并且只能识别 1 个参数。做这样的事情：

public function findList($diplomes,$categories,) {
    $qb=$this->createQueryBuilder('c');

    if($categories!=null){
        $qb->andWhere('c.categorie IN (:categories)')
            ->setParameter(':categories', $categories);
    }

    if($diplomes!=null) {
        $qb->andWhere('c.diplome IN (:diplomes)')
            ->setParameter(':diplomes', $diplomes);
    }

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