Multiple files in POST

[sladdky]

If you try to upload two files in POST and one is empty (in case of both being empty, the issue occurs as well, but I'm not sure now),

Contributte\Psr7\Psr7ServerRequest::normalizeNetteFiles

will throw exception

InvalidArgumentException('Invalid value in files specification').

If you try to upload multiple files in POST as array (type='file[1]', type='file[2]'), it throws exception again because parameter array $files contains inner arrays.

intended or am I doing anything wrong?

for now I modified method of Contributte\Psr7\Psr7ServerRequest to accept recursive arrays and ignore empty files:

public static function normalizeNetteFiles(array $files)
    {
        $normalized = [];

        foreach ($files as $file) {
            if ($file instanceof FileUpload) {
                $normalized[] = new Psr7UploadedFile(
                    $file->getTemporaryFile(),
                    intval($file->getSize()),
                    $file->getError(),
                    $file->getName(),
                    $file->getContentType()
                );
            } else if (is_array($file)) {
                $normalized = array_merge($normalized, self::normalizeNetteFiles($file));
            } else if ($file === null) {
                continue;
            } else {
                throw new InvalidArgumentException('Invalid value in files specification');
            }
        }

        return $normalized;
    }

Hi, thanks for an issue. I need to check it manually. Could you please describe when file is empty?

This package is being used in apitte. Here's my code of a controller and a form.

/**
 * @Controller
 * @ControllerPath("/test")
 */
final class TestController extends BaseController
{
    /**
     * @Path("/")
     * @Method("POST")
     */
    public function index(ApiRequest $request, ApiResponse $response)
    {
        $files = [];

        foreach ($request->getUploadedFiles() as $file) {
            $files[] = $file;
        }

        return $response->withStatus(420, strval(count($request->getUploadedFiles())));
    }
}

<form action="http://localhost/test" method="POST" enctype="multipart/form-data">
    <input type="file" name="file1">
    <input type="submit">
</form>

if sent without image, exception is thrown that cannot be caught in the controller.

By empty file I meant empty field, thus no file being send.

You be fixed. Could you please test it @Odoaker-Alaric ?

I'll have to try it somewhere separately, the project I am working on uses apitte/core, apitte/debug, apitte/middlewares and all require lower versions of this library and I didn't manage to forceupdate psr7-http-message to version 0.5, it always kicks it back to 0.3. If it's the same code I suggested, it should be fine tho. Works for me in my personal project. 2018-06-28 7:39 GMT+02:00 Milan Felix Šulc <notifications@github.com>:

Yep, it will be in apitte v0.4. We will release v0.3 with some tiny improvements and then v0.4 will be with PHP 7.1

You can trick it with contributte/psr-7-http-message: "dev-master as 0.3.

It should use dev-master branch and for the rest of the packages it looks like same old v0.3.

Cool trick, so far so good.
Works as intended.
