Symfony和主义-ParameterBag无法转换为字符串 [英] Symfony and Doctrine - ParameterBag could not be converted to string

问题描述

我收到此错误：

可捕获的致命错误：类
的对象Symfony\Component\HttpFoundation\无法将ParameterBag
转换为字符串

Catchable Fatal Error: Object of class Symfony\Component\HttpFoundation\ParameterBag could not be converted to string

我使用Symfony 3和Doctrine Query Builder

I use Symfony 3 and Doctrine Query Builder

$qb = $this->getEntityManager()->createQueryBuilder();
        $qb->select('c')
                ->from('AppBundle:Certificate', 'c')
                ->where(' c.enabled = 1')
                ->where(' c.title LIKE :search')
                ->orderBy('c.title', $order)
                ->setParameter('search', '%' . $search . '%' );

        $query = $qb->getQuery();

        return $query->getResult();

我尝试像这样将_toString添加到我的实体中：

I try add _toString to my Entity like this:

public function __toString() {
        return $this->title;
    }

但我没有更改它，我将需要使用c列与LIKE相同的搜索其中（cc1相似：搜索或cc2相似：搜索）

but I have not changed it, I will need to use c columns for the same search with LIKE where(cc1 LIKE: search OR cc2 LIKE: search)

有什么解决方案吗？我需要用LIKE搜索两列，其中有给定的搜索字符串，并且必须使用％：search％

Is there any solution? I need to search with LIKE two columns in which the given search string and I must use %:search%

谢谢

推荐答案

ParameterBag对象必须用于请求对象检索的$ order或$ search参数。尝试在查询之前将其转储，以查看内部内容。

The ParameterBag object must be for your $order or $search parameters retrieve by the request object. Try to dump it before the query in order to see what there is inside.
