Question

您好我正在尝试使用Annonce和一些图像之间的oneToMany关系进行文件上传;因此，Annonce可以包含0个或更多图像，并且图像仍然附加到Annonce。我认为我的实体一切正常，但是当我提交表单时我收到了这个错误。

}

ImageType.php

<?php

namespace MDB\PlatformBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class ImageType extends AbstractType {

    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder
                ->add('file')
        ;
    }

    /**
     * @param OptionsResolverInterface $resolver
     */
    public function setDefaultOptions(OptionsResolverInterface $resolver) {
        $resolver->setDefaults(array(
            'data_class' => 'MDB\PlatformBundle\Entity\Image'
        ));
    }

    /**
     * @return string
     */
    public function getName() {
        return 'mdb_platformbundle_image';
    }

}

我在表单提交时出现以下错误：

属性“images”和其中一种方法都没有 “addImag（）”/“removeImag（）”，“addImage（）”/“removeImage（）”， “setImages（）”，“images（）”，“__ set（）”或“__call（）”存在并具有 “MDB \ AnnonceBundle \ Entity \ Annonce”中的公共访问。

我不明白因为我的实体中存在这些getter。有人有想法吗？

谢谢

此错误是逻辑错误。只需使用集合字段类型解决问题
