如何使用Doctrines Query Builder定义多个查询或在哪里查询

我想使用Doctrines QueryBuilder创建查询。

用户可以选择将通过选中或取消选中HTML表单中的复选框来搜索的数据库字段。这就是$_POST contains 'filters'和“喜欢”的原因。

$_POST['filters']看起来像这样:

array(2) { [0]=> string(4) "rack" [1]=> string(5) "shelf" } 

我正在尝试获得以下查询结果

SELECT * FROM `inventories` WHERE (`rack` OR `shelf` LIKE '%01%') AND `checkedOutAt` IS NULL ORDER BY `lastChangedAt`

我在版本2.5.5中使用Doctrine,在版本7中使用PHP。我的控制器如下所示:

public function searchAction()
{
    $filters = array();
    $em = $this->getEntityManager();
    $vendors = $em->getRepository('Entities\Vendor')->findAll();

    if ($_POST)
    {
        $filters = $_POST['filters'];
        $like = trim($_POST['like']);
        $inventories = $em
            ->getRepository('Entities\Inventory')
            ->findInventoriesBySearch($like, $filters)
        ;
        $this->addContext('like', $like);
    }
    else
    {
        $inventories = $em
            ->getRepository('Entities\Inventory')
            ->findInventories()
        ;
    }

    $count = count($inventories);

    $this->addContext('filters', $filters);
    $this->addContext('vendors', $vendors);
    $this->addContext('inventories', $inventories);
    $this->addContext('count', $count);
    $this->setTemplate('inventoryAction');
}

然后是相应的存储库(“ findInventories()”存储库功能可以正常工作):

public function findInventoriesBySearch($like, $filters)
{
    $em = $this->getEntityManager();
    $orExpr = $qb->expr()->orX();

    foreach ($filters as $filter)
    {
        $orExpr->add($qb->expr()->like($filter, $like));
    }

    $qb ->andWhere('i.checkedOutAt is NULL');
    $qb->setParameter('like', '%' . $like . '%');
    $qb->select('i')->where($orExpr)->addOrderBy('i.lastChangedAt', 'DESC');

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

运行脚本时,我收到以下错误消息:

尝试检查并更改它。

  1. (仅是一个建议)请勿与$_POST /请求类型/访问权限等一起使用。通过“您的方式”。使用带有类型提示的Request,例如:

    public function searchAction(Request $request){
    
       if ($request->isMethod('POST')) {
         $filters = $request->request->get('filters');
    
         //.....
       }else{
    
       }
    }
    
  2. 猜猜,这里存在问题:

    //...
    foreach ($filters as $filter)
    {
       $filter = 'i.'.$filter; // <== 'i.rack','i.shelf', so on
       $orExpr->add($qb->expr()->like($filter, $like));
    }
