Php 在Symfony2中分解实体对象

我正在尝试在我的Symfony2 Web应用程序中创建图库

每一篇文章可能有也可能没有图库。我的图库是文本映射类型，位于Post实体/类下：

#Post.orm.yml

MyProject\MyProjectBundle\Entity\Post:
type: entity
table: post
repositoryClass: MyProject\MyProjectBundle\Entity\PostRepository
    id:
        id:
            type: integer
            generator: { strategy: AUTO }
    fields:
        # ...
        gallery:
            type: text
            nullable: true
        #...

由于图库中有许多图像，我认为通过我的数据装置用逗号分隔每个图像是有意义的：

image1.png, image2.jpg, examplename-3rdimage.gif, 4thandfinal.jpg

但是，我希望在查看库时将其输出如下：

<li>image1.png</li>
<li>image2.jpg</li>
<li>examplename-3rdimage.gif</li>
<li>4thandfinal.jpg</li>

您可能已经注意到，我从我的存储库类中引用了函数：

getGallery（）

：

PostRepository

：

/* PostRepository.php */

class PostRepository extends EntityRepository
{
    public function getGallery()
    {
        $postGallery = $this->createQueryBuilder('e')
                            ->select('e.gallery')
                            ->getQuery()
                            ->getResult();

        $gallery = array();
        foreach ($postGallery as $postGal)
        {
            $gallery = array_merge(explode(",", $postGal['gallery']), $gallery);
        }

        foreach ($gallery as &$gal)
        {
            $gal = trim($gal);
        }

        return $gallery;
    }
}

最后，我的细枝文件：

postshow.html.twig

，如下所示：

{% for gallery in gallery %}
    <li>{{ gallery }}</li>
{% endfor %}

/* PostController.php */

public function postshowAction($id)
{
    $em = $this->getDoctrine()->getManager();

    $entities = $em->getRepository('MPMPBBundle:Post')->find($id);

    $gallery = null;
    if (null !== $entities->getGallery())
    {
        $gallery = explode(",", $entities->getGallery());
        $gallery = array_map("trim", $gallery);
    }

    if (!$entities) {
        throw $this->createNotFoundException('Unable to find Post entity.');
    }

    return $this->render('MPMPBBundle:Post:postshow.html.twig', array(
        'entities'      => $entities,
        'gallery'       => $gallery
    ));
}

---

gallery

字段位于

Post

表中，因此您无需在数据库中再次查询，只需从当前实体中获取

gallery

，然后按如下方式进行分解（）

{% for gallery in gallery %}
    <li>{{ gallery }}</li>
{% endfor %}

/* PostController.php */

public function postshowAction($id)
{
    $em = $this->getDoctrine()->getManager();

    $entities = $em->getRepository('MPMPBBundle:Post')->find($id);

    $gallery = null;
    if (null !== $entities->getGallery())
    {
        $gallery = explode(",", $entities->getGallery());
        $gallery = array_map("trim", $gallery);
    }

    if (!$entities) {
        throw $this->createNotFoundException('Unable to find Post entity.');
    }

    return $this->render('MPMPBBundle:Post:postshow.html.twig', array(
        'entities'      => $entities,
        'gallery'       => $gallery
    ));
}

我太。。。我太慢了。我确信这是显而易见的，但我不认为这是显而易见的。谢谢。我很感激。

/* PostController.php */

public function postshowAction($id)
{
    $em = $this->getDoctrine()->getManager();

    $entities = $em->getRepository('MPMPBBundle:Post')->find($id);

    $gallery = null;
    if (null !== $entities->getGallery())
    {
        $gallery = explode(",", $entities->getGallery());
        $gallery = array_map("trim", $gallery);
    }

    if (!$entities) {
        throw $this->createNotFoundException('Unable to find Post entity.');
    }

    return $this->render('MPMPBBundle:Post:postshow.html.twig', array(
        'entities'      => $entities,
        'gallery'       => $gallery
    ));
}
