ZF2上具有集合的FilePrg

我需要使用fileprg插件提交包含一些字段以及最多3张图像的表格，以保存上载的文件，以防出现一些验证错误。

我不想切换到其他解决方案（例如将表单拆分为子表单，或删除集合以支持三个不同的文件字段）。我遇到的主要问题是，当用户提交无效文件（太大或mimetype无效）时，我想报告该错误并允许上传其他文件。相反，发生的事情是该集合从表单中消失了。

如果用户根本不提交文件（即使需要文件），也会发生相同的情况。在使用自己的代码进行测试之后，我决定对cgmartin代码进行测试，无论如何都会发生这种情况。

我知道这可能像该问题的重复部分一样被禁止，但是我在这一问题上停留了几天。

这是我的cgmartin代码的“分支”（实际上，我在控制器中添加了fileprg，视图和表单都保持不变）。谢谢。一种。

public function collectionAction()
{
    $form = new Form\CollectionUpload('file-form');
    $prg = $this->fileprg($form);


    if ($prg instanceof \Zend\Http\PhpEnvironment\Response) {
        $this->getServiceLocator()->get('Zend/Log')->debug("Redirect to Get!");
        return $prg; // Return PRG redirect response
    } elseif (is_array($prg)) {


            if ($form->isValid()) {
                //
                // ...Save the form...
                //
                return $this->redirectToSuccessPage($form->getData());
            }

    }

    return array('form' => $form);
}
