Post files using cURL

[codealfa]

It's impossible to post files by http using cURL via the WordPress API.

If you look at the code in the setup_handle method in Requests_Transport_cURL class found in the /wp-includes/Requests/Transport/cURL.php file, you'll see that the POST data is always converted to a string using the PHP http_build_query function. However, according to the PHP manual at ​http://www.php.net/manual/en/function.curl-setopt.php, the value passed to CURLOPT_POSTFIELDS must be an array if files are passed to this option.

A possible fix could be to simply add the post value to the CURLOPT_POSTFIELDS option without converting it to a string if the value is an array and the Content-Type header has been given as multipart/form-data. According to the PHP manual, this Content-Type header will be set if the post value is an array.
