问题
您好，我正在使用 Symfony CMF 1.2、liip/imagine-bundle 1.3、symfony-cmf/media-bundle 1.2。我想向我的扩展 ImagineBlock 的块添加 2 个额外的图像字段，因为对于我上传的每张图像，都会有一个移动和平板电脑版本的图像，这不是简单的调整大小、纵横比或诸如此类的东西不相似。我不能在不影响图像质量的情况下裁剪/调整大小。

if (null === $this->getParentFieldDescription()) {
$imageRequired = ($this->getSubject() && $this->getSubject()->getParentDocument()) ? false : true;
$formMapper
->with('form.group_general')
->remove('parentDocument')
->remove('filter')
->add('parentDocument', 'hidden', ['required' => false, 'data' => 'filler'])
->add('name', 'hidden', ['required' => false, 'data' => 'filler'])
->add('imageMobile', 'cmf_media_image', array('required' => $imageRequired))
->add('imageTablet', 'cmf_media_image', array('required' => $imageRequired))
->end();
// Append common fields to FormMapper
$commonFormMapper = new CommonFormMapper($formMapper);
$formMapper = $commonFormMapper->getPublishingFields();
}
}
}
注意我无法将服务容器注入到这个类（通过构造函数/方法），这就是为什么我现在使用硬编码的节点路径和实例化的 Slugify 类而不是使用它的服务。我也很乐意解决这个问题。参考 -
xx.main.admin.pageadmin.container:
class: xx\MainBundle\Admin\PageAdmin
calls:
- [setContainer,[ @service_container ]]
# arguments: ["@service_container"]
图像字段上的注释基于我在中找到的以下配置
\vendor\symfony-cmf\block-bundle\Resources\config\doctrine-phpcr\ImagineBlock.phpcr.xml：
<doctrine-mapping
xmlns="http://doctrine-project.org/schemas/phpcr-odm/phpcr-mapping"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://doctrine-project.org/schemas/phpcr-odm/phpcr-mapping
https://github.com/doctrine/phpcr-odm/raw/master/doctrine-phpcr-odm-mapping.xsd"
>
<document
name="Symfony\Cmf\Bundle\BlockBundle\Doctrine\Phpcr\ImagineBlock"
referenceable="true"
translator="attribute"
>
<node name="node"/>
<locale name="locale"/>
<field name="label" type="string" translated="true" nullable="true"/>
<field name="linkUrl" type="string" translated="true" nullable="true"/>
<field name="filter" type="string" nullable="true"/>
<child name="image" node-name="image">
<cascade>
<cascade-persist/>
</cascade>
</child>
</document>
</doctrine-mapping>
结果
虽然默认的“图像”字段正常保留，但没有考虑其他两个添加的图像字段，因为当我在 prePersist 上进行调试时，我看到两个字段都为空，而图像字段包含其上传的文件。
我尝试添加一个正常的文本字段，该字段在我的页面上正常保存和显示。
我在我的项目中使用 YAML，所以我不确定给定的 XML 是如何翻译的，如果它是要定义的正确映射。
请帮忙。:)
