Upload files in subarrays

[oscarotero]

Hi.
It seems that this library does not handle upload files in subarrays. For example, I have a form with this both fields:

<input type="file" name="images[big]" >
<input type="file" name="images[small]" >

On submit the form, I have a $_FILES like this:

Array
(
    [images] => Array
        (
            [name] => Array
                (
                    [big] => 14417316530_7c593bdff2_m.jpg
                    [small] => 14987901784_79fa14dacc_z.jpg
                )

            [type] => Array
                (
                    [big] => image/jpeg
                    [small] => image/jpeg
                )

            [tmp_name] => Array
                (
                    [big] => /private/var/tmp/phpuVQC7S
                    [small] => /private/var/tmp/phppe8WJs
                )

            [error] => Array
                (
                    [big] => 0
                    [small] => 0
                )

            [size] => Array
                (
                    [big] => 14377
                    [small] => 84186
                )
        )
)

On create a ServerRequest using ServerRequestFactory I have the following error:

<b>Fatal error</b>:  Uncaught exception 'InvalidArgumentException' with message 'Invalid leaf in uploaded files structure' in /Volumes/Documentos/www/psr7-test/vendor/zendframework/zend-diactoros/src/ServerRequest.php:293

I guess ServerRequestFactory should normalize the $_FILES array, somethink like symfony httpfoundation does

[samsonasik]

handled by #57 ?

[jonhudson]

Yes, #57 should fix this.
