}

可以看出，产品和类别通过表product_to_catagory链接。

我正在使用doctrines object multi复选框来使用

获取产品的类别

$this->add(array(
            'name' => 'categories',
            'type' => 'Admin\DoctrineModule\Form\Element\ObjectMultiCheckbox',
            'options' => array(
                'label' => _('Categories:'),
                'label_attributes' => array('class' => 'required'),
                'object_manager' => $this->getEntityManager(),
                'target_class' => 'Application\Entity\Categories',
                'property' => 'category',
                'is_method' => true,
                'find_method' => array(
                    'name' => 'FindAll',
                ),
                'disable_inarray_validator' => true,
            ),
        ));

表单绑定到产品实体

提交表单后，产品实体中的类别将返回Doctrine \ Common \ Collections \ ArrayCollection

我遇到的问题是，当我清空产品实体时，product_to_catagory表中的数据库没有保存在数据库中。

有谁知道我做错了什么？

非常感谢提前。

EDIT 将拥有方改为产品，代码更新。
