php - ZF2 文件上传合集

Question

我无法使我的文件上传集合正常工作。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 本身是有效的。但是一旦 InputFilter 运行数据，所有数据都会丢失。显然 FileRenameUpload 做了一些可疑的事情，我无法弄清楚到底是什么。我只知道我的数据丢失了......

写权限不是问题。我目前正在通过 PHP 5.5 CLI 在 Windows 上的 devbox 上对此进行测试

看起来问题出在元素的集合上。过去，仅支持将 Fieldset 放入集合中。也许稍后会添加元素支持，但我很确定它有问题，因此不会以这种方式为您工作。我重新编写了您的代码以使用 Fieldsets，并验证了它，并正确地重命名和移动了上传的文件。问题出在 CollectionInputFilter 内部，似乎没有正确更新以支持元素集合。

可能很明显:确保在验证之前准备好集合。

这是我修改后的代码分支:https://gist.github.com/netiul/efaf8bd4545d216fd26c

Controller

public function indexAction()
{
    $request = $this->getRequest();

    if($request->isPost())
    {
        $post = array_merge_recursive(
            $request->getPost()->toArray(),
            $request->getFiles()->toArray()
        );

        $this->incidentForm->prepare();

        $this->incidentForm->setData($post);

        if($this->incidentForm->isValid()) {
            \Zend\Debug\Debug::dump($this->incidentForm->getData());
            die();
        }
    }

    return [
        'form' => $this->incidentForm
    ];
}

TheFilter(没有改变，一个小的改变)

    $singleFileFilter = new InputFilter();
    $singleFileFilter->add(
        [
            'name'     => 'attachment',
            'required' => false,
            'filters'  => [
                [
                    'name'    => 'filerenameupload',
                    'options' => [
                        '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');

形式

    $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([
            'class' => 'form-control'
        ]);

    $collectionTarget = new Form\Fieldset('uploadItem');
    $collectionTarget->add($fileElement);

    $this->add(
        [
            'name'    => 'attachedFiles',
            'type'    => 'collection',
            'options' => [
                'count'          => 3,
                'target_element' => $collectionTarget
            ]
        ]
    );

验证后的输出

  'attachedFiles' => 
    array (size=3)
      0 => 
        array (size=1)
