Question

实际上，我正在使用Doctrine的setParame进行查询，但如果我尝试获取查询，则会看到参数未设置。

代码是这样的：

$query = $this->createQueryBuilder('l')
            ->where('l.project = :projectId')
            ->andWhere('l.state.value != :deletedState')
            ->setParameters([
                'projectId' => $project->getId(),
                'deletedState' => LandingState::STATE_DELETED,
            ]);

如果我制作一个var_dump

，这就是我得到的查询

'SELECT l0_.lan_id AS lan_id_0, l0_.lan_title AS lan_title_1, 
l0_.lan_url AS lan_url_2, l0_.lan_testimony AS lan_testimony_3, 
l0_.lan_testimony_content AS lan_testimony_content_4, 
l0_.lan_final_claim AS lan_final_claim_5, l0_.lan_service_ids AS 
lan_service_ids_6, l0_.lan_state AS lan_state_7, l0_.lan_index AS 
lan_index_8, l0_.lan_follow AS lan_follow_9, l0_.lan_script AS 
lan_script_10, l0_.lan_date_insert AS lan_date_insert_11, 
l0_.lan_date_update AS lan_date_update_12, l0_.pro_id AS pro_id_13, 
l0_.lan_image AS lan_image_14, l0_.lan_testimony_image AS 
lan_testimony_image_15 FROM landing l0_ WHERE l0_.pro_id = ? AND 
l0_.lan_state <> ?'

但是如果我试图获得$ project-＆gt; getId（）或带有echo的LandingState :: STATE_DELETED的值，我得到的值。为什么查询中没有设置的值？

Answer 1

我看到的方式没有错，看看这个简单的例子来理解：

控制器中的代码：

$search = 'test';
    $em = $this->getDoctrine()->getManager();
    $queryBuilder = $em->createQueryBuilder();
    $queryBuilder->select('d')
        ->from('BackBundle\Entity\disponibility', 'd')
        ->where('d.name like :search')
    ->setParameter('search', '%' .$search. '%');
    $query = $queryBuilder->getQuery();

    dump($query->getSQL());
    dump($query);

转储的内容：

$查询 - ＆GT; getSQL（）;

"SELECT d0_.id AS id0, d0_.name AS name1 FROM disponibility d0_ WHERE d0_.name LIKE ?"

$查询;

最后来自symfony profiler的查询：

    SELECT count(DISTINCT d0_.id) AS sclr0 FROM disponibility d0_ WHERE d0_.name LIKE ?

Parameters: ['%test%']

正如您所看到的，Doctrine的SetParameter工作正常，但dump函数不会显示参数。如果要查看参数，请在分析器中查看它们

SetParameters of doctrine不起作用
