Description:
Add support for base64 Content-Transfer-Encoding in "multipart/form-data" posts.

When I try to use the following:

I get this error:
<?xml version="1.0"?><api servedby="mw38"><error code="verification-error" info="This file did not pass file verification"><details><detail>filetype-mime-mismatch</detail><detail>gif</detail><detail>text/plain</detail></details></error></api>

This is properly base64 encoded, and will decode to a gif.

Version: unspecified
Severity: enhancement

In your Content-Disposition you specify that the original filename has a jpg extension, while you claim that it is a give. Are you sure that the filename parameter that you specify has the correct extension?

Unfortunately closing this report as no further information has been provided.

Smallman: Please feel free to reopen this report if you can provide the information asked for in comment 1. Thanks!

I can verify that: The mime is set to png and I upload a png (without using BASE64 it works).

Anomie changed the task status from Open to Stalled.Feb 20 2015, 4:12 PM

Anomie added a project: Upstream.

Anomie set Security to None.

PHP doesn't decode this data, or even tell us whether there was a Content-Transfer-Encoding header. And it's not entirely clear whether RFC 2616 § 19.4.5 stating that HTTP doesn't use Content-Transfer-Encoding applies to all subparts of multipart/form-data or not.

See PHP bug 48219 for details. Until something happens there, there's nothing we're likely to do here.
