[wp-hackers] POSTing a file via wp_remote_post

[Dion Hulse (dd32)]

Short story: WP_HTTP Doesn't handle posting of files.

You may be able to do it by building the HTTP Payload yourself and
passing it as a string to the 'body' param:
wp_remote_post( $url, array(
   'body' => $payload
) );

You'd need to somehow manage to get the multipart/form-data
Content-Type working, I'm not sure how easy that would be to achieve
using only the body parameter though.

I'd pull up Wireshark and grab a HTTP payload to see if it can be
done, but I don't have access to it right now..
