Hi,

I try to use Zend Expressive, but I don’t understand how use FileRenameUpload and I can’t valid my form.

```
if ($request->getMethod() === 'POST') {
            $this->imageForm->setData(array_merge($request->getParsedBody(), $request->getUploadedFiles()));
            if ($this->imageForm->isValid()) {
                dd($this->imageForm->getData());
            }
        }

```

I put this in my form class to move file after upload :

```
public function getInputFilterSpecification()
    {
        return [
            [
                'name' => 'file',
                'required' => true,
                'filters' => [
                    [
                        'name' => 'FileRenameUpload',
                        'options' => [
                            'target' => __DIR__.'../../../data/upload',
                            'useUploadName' => true,
                            'useUploadExtension' => true,
                            'overwrite' => true,
                            'randomize' => true
                        ]
                    ]
                ],
            ]
        ];
    }

```

But when I do isValid on form, just this error :

> ```
> "fileUploadFileErrorNoFile" => "File was not uploaded"
> 
> ```

I don’t understand how use a Stream and valid it

I do right ? I readed doc but nothing about upload and valid form for Expressive.

Thanks

The various file validators and input types do not currently work with PSR-7, which is what Expressive uses. You will have to handle those separately currently.

We’re working on a new validation/input filter component ([spec](https://discourse.zendframework.com/t/rfc-new-validation-component/208)), and will likely tackle file upload validation, filtering, etc. in that component.

For now, you can use `Psr7Bridge` like this:

```php
use Zend\Psr7Bridge\Psr7ServerRequest;

$zendRequest = Psr7ServerRequest::toZend($request);
$this->imageForm->setData(\array_merge_recursive(
        $zendRequest->getPost()->toArray(),
        $zendRequest->getFiles()->toArray()
));

```

Funny enough, I was just going to write a similar question. Saved some time now though I did not find a ready-to-use solution.

Hi,

thanks you for your fast replies. (and for your blog samsonasik 😃 )

I didn’t read anything about non-fonctinal validators and inputfilters.

I took Psr7Bridge and it works like a charm.

There is a cleaner how to way to do this ?

You’re welcome Ralf.

As of zend-filter 2.9, it can now be done without a bridge.  
[https://docs.zendframework.com/zend-filter/file/](https://docs.zendframework.com/zend-filter/file/)  
Look for PSR-7 section.

Configuration can now be:

```auto
use Zend\Diactoros\StreamFactory;
use Zend\Diactoros\UploadedFileFactory;

public function getInputFilterSpecification()
    {
        return [
            [
                'name' => 'file',
                'required' => true,
                'filters' => [
                    [
                        'name' => 'FileRenameUpload',
                        'options' => [
                            'target' => __DIR__.'../../../data/upload',
                            'useUploadName' => true,
                            'useUploadExtension' => true,
                            'overwrite' => true,
                            'randomize' => true,
                            'stream_factory' => new StreamFactory(),
                            'upload_file_factory' => new UploadedFileFactory(),
                        ]
                    ]
                ],
            ]
        ];
    }

```

that may only works for filter, for validation, eg: Size, MimeType, it still needs Psr7bridge, refs [https://github.com/zendframework/zend-form/issues/227](https://github.com/zendframework/zend-form/issues/227)

Ah, did not realize there were still more. Sorry for oversight, and thank you for testing. Will try to get the rest of them done.
