我无法让我的fileupload集合正常工作。这就是我所做的：
基本上$request->getFiles()包含正确的信息。所以上传到PHP本身就可以了。但是一旦InputFilter运行数据，它就会丢失。显然FileRenameUpload做了一些蠢事，我无法弄清楚到底是什么。我所知道的是我的数据丢失了......
写权限不是问题。我正在通过PHP 5.5 CLI在Windows上的devbox上测试这个

看起来问题是元素的集合。过去，只有Fieldsets支持在Collection中。也许稍后会添加Element支持，但我很确定它是错误的，因此不会以这种方式为您工作。我重新编写了代码以使用Fieldsets，我对其进行了验证，并且上传的文件已正确重命名并移动。问题出在CollectionInputFilter中，似乎没有正确更新以支持元素集合。
可能很明显：确保在验证前准备好这个集合。

TheFilter（没有改变，改变很小）
$singleFileFilter = new InputFilter();
$singleFileFilter->add(

[
'name' => 'filerenameupload',

'target' => 'data/incident_attachments/', /* small change here, removed the slash in front of data to make the path relative */
'randomize' => true,
'use_upload_name' => false,
'overwrite' => false
]
]
]
]
);
$attachedFilesFilter = new CollectionInputFilter();
$attachedFilesFilter->setInputFilter($singleFileFilter);
$this->add($attachedFilesFilter, 'attachedFiles');
<强> TheForm
$this->setAttribute('enctype', "multipart/form-data");
$fileElement = new Form\Element\File('attachment');
$fileElement->setOptions(
[
'label' => 'Add Attachment',
'label_attributes' => [
'class' => 'control-label col-sm-3'

$fileElement->setAttributes([

$collectionTarget = new Form\Fieldset('uploadItem');
$collectionTarget->add($fileElement);
$this->add(
[
'name' => 'attachedFiles',
'type' => 'collection',

验证后输出
