Symfony查询结果返回空字符串以进行工作查询（查询结果来自DB）

Question

我正在为我的应用程序构建自定义搜索查询。问题是查询结果是空的，但是当我在phpMyAdmin中运行相同的查询（来自debug的runnable query）时，我得到了预期的结果。

someoen知道问题出在哪里：

这是代码：

class ProductRepository extends EntityRepository
{
  public function findByParameters($searchParameters)
  {
      $condition = $this->createQueryBuilder('p')
        ->where('p.state LIKE :state')
        ->setParameter('state', 0);
      if(isset ($searchParameters["title"])){
        $condition
          ->andWhere('p.title LIKE :title')
          ->setParameter('title', $searchParameters["title"]);
      }
      if(isset ($searchParameters["categories"])){
        $condition
          ->andWhere('p.categories IN (:categories)')
          ->setParameter('categories', $searchParameters["categories"]);
      }
      if(isset ($searchParameters["productCondition"])){
        $condition
          ->andWhere('p.productCondition = :productCondition')
          ->setParameter('productCondition', $searchParameters["productCondition"]);
      }
      $condition
        ->getQuery()
        ->getResult();
    return $condition;
  }
}

Symfony debug doctrine log：

SELECT t0.id AS id_1, t0.name AS name_2, t0.surname AS surname_3, t0.username AS username_4, t0.password AS password_5, t0.email AS email_6, t0.created AS created_7, t0.roles AS roles_8 FROM users t0 WHERE t0.id = ?
Parameters: [0 => 5]

  t0.id AS id_1, 
  t0.name AS name_2, 
  t0.surname AS surname_3, 
  t0.username AS username_4, 
  t0.password AS password_5, 
  t0.email AS email_6, 
  t0.created AS created_7, 
  t0.roles AS roles_8 
FROM 
  users t0 
WHERE 
  t0.id = ?
SELECT t0.id AS id_1, t0.name AS name_2, t0.surname AS surname_3, t0.username AS username_4, t0.password AS password_5, t0.email AS email_6, t0.created AS created_7, t0.roles AS roles_8 FROM users t0 WHERE t0.id = 5;

修改

这是来自symfony debug的runnable查询，它在phpMyAdmin中工作：

SELECT p0_.id AS id_0, p0_.state AS state_1, p0_.title AS title_2, p0_.content AS content_3, p0_.price AS price_4, p0_.images AS images_5, p0_.created_at AS created_at_6, p0_.updated_at AS updated_at_7, p0_.expires_at AS expires_at_8, p0_.condition_id AS condition_id_9, p0_.user_id AS user_id_10 FROM product p0_ WHERE p0_.state LIKE 0 AND p0_.title LIKE 'Pc';

更新：

I checked Doctrine logs and I am getting this error too:

AppBundle\Entity\Product    
The association AppBundle\Entity\Product#productCondition refers to the inverse side field AppBundle\Entity\ProductCondition#products which does not exist.
The association AppBundle\Entity\Product#user refers to the inverse side field AppBundle\Entity\User#products which does not exist.

您在此处提到的调试查询与您的实际教义查询不匹配。 如果你去Symfony profiler＆gt; Doctrine，会有一个查询列表。

如果您可以找到与您的学说匹配的一个并在phpmyadmin中运行它或将其粘贴到此处，那么找到问题会很有帮助。
