有没有办法从实体存储库写入闪存消息。我有一个标签和类别实体。我正在通过类别表单添加标签,我在其中添加了一个自定义输入字段,该字段接收用“,”分隔的标签。每次我提交表单时,我都会检查输入中的标签是否已经存在,如果不存在,我会将它们添加到数据库中,然后将它们添加到 Category 实体中。
这是我的标签存储库,我试图在其中编写 flashmessage:
namespace Kpr\CentarZdravljaBundle\Entity;
use Doctrine\ORM\EntityRepository;
use Doctrine\Common\Collections\ArrayCollection;
use Kpr\CentarZdravljaBundle\Entity\Tags;
use Symfony\Component\HttpFoundation\Request;
class TagsRepository extends EntityRepository
{
public function findByTagInput($arg)
{
$request = Request::createFromGlobals();
$args = explode(", ", $arg);
$em = $this->getEntityManager();
$tagArray = array();
$addaedTags = "";
foreach($args as $name){
$tag = $this->findByName($name);
if(!$tag){
$addaedTags .= $name.", ";
$newTag = new Tags();
$newTag->setName($name);
$newTag->setApproved(1);
$em->persist($newTag);
$tagArray[] = $newTag;
}
}
if($addaedTags!="") $request->get('session')->getFlashBag()->add('info', substr($addaedTags,0,strlen($addaedTags)-2));
$qb = $em->createQueryBuilder();
$qb->add('select', 'tag')
->add('from', 'KprCentarZdravljaBundle:Tags tag')
->add('where', $qb->expr()->in('tag.name', $args));
// $qb instanceof QueryBuilder
$query = $qb->getQuery();
// Set additional Query options
$query->useResultCache('my_cache_id');
$results = $query->getResult();
/*
$sql = "SELECT * FROM categories WHERE $whereS";
$stmt = $this->getEntityManager()->getConnection()->prepare($sql);
$results = $stmt->execute();
*/
$totalResults = array_merge($tagArray, $results);
$tags = new ArrayCollection($totalResults);
return $tags;
}
public function findByName($name)
{
$qb = $this->getEntityManager()->createQueryBuilder();
$qb->add('select', 'tag')
->add('from', 'KprCentarZdravljaBundle:Tags tag')
->add('where', 'tag.name = :namearg')
->setParameter('namearg', $name);
// $qb instanceof QueryBuilder
$query = $qb->getQuery();
$result = $query->getResult();
return $result;
}
}
我得到的错误:
FatalErrorException: Error: Call to a member function getFlashBag()
on a non-object in /home/kprhr/public_html/CZ_Symfony/src/Kpr/CentarZdravljaBundle/Entity/TagsRepository.php line 31
