Curl file upload with multipart/form-data

I have a problem with the file upload with curl. I want to upload a file of my server on a video hosting site. The script needs the Content-type: multipart/form-data and Content-type: video/mp4, but I dont know how I can do it. After the upload the file have the content type application/octet-stream.

Here is the script

class curl
{
         function __construct($use = 1)
         {
         $this->ch = curl_init();
                 if($use = 1)
                 {
                         curl_setopt ($this->ch, CURLOPT_POST, 1);
                         curl_setopt ($this->ch, CURLOPT_COOKIEJAR, 'cookie.txt');
                         curl_setopt ($this->ch, CURLOPT_FOLLOWLOCATION, 1);
                         curl_setopt ($this->ch, CURLOPT_RETURNTRANSFER, 1);
                 }
                 else
                 {
                         return 'There is the possibility, that this script wont work';
                 }
         }
         function first_connect($loginform,$logindata)
         {
                 curl_setopt($this->ch, CURLOPT_URL, $loginform);
                 curl_setopt($this->ch, CURLOPT_POSTFIELDS, $logindata);
         }
         function store()
         {
                 $this->content = curl_exec ($this->ch);
         }
         function execute($page)
         {
                 curl_setopt($this->ch, CURLOPT_URL, $page);
                 $this->content = curl_exec ($this->ch);
         }
         function close()
         {
                 curl_close ($this->ch);
         }

         function __toString()
         {
         return $this->content;
         }

         function upload($file)
         {
            curl_setopt($this->ch, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data"));
            curl_setopt($this->ch, CURLOPT_URL, 'http://uploadsite.com/index.php?act=files&do=upload');
            $postdata = array("file[]" => "@/".realpath($file));
            echo $postdata;
            curl_setopt($this->ch, CURLOPT_POSTFIELDS, $postdata);
            curl_exec ($this->ch);
         }
}


$getit = new curl();
$getit->first_connect('http://uploadsite.com/index.php?act=login&login=true','login=true&file_session=&email=xxx%40yahoo.de&password=xxx&upload=Login');
$getit->store();
$getit->execute('http://uploadsite.com/index.php?act=user&do=home');
$getit->upload('Sample.mp4');

And the package from livehttpheaders

I've used curl for connecting with a web service and upload a file using a similar idea of this post, but it didn't work. The reasons where different to the previous answer, so I will describe my solution; maybe my experience is useful to others.

I had two problems. The first one is that my web service didn't like absolute path in the filename. If $file in the OP code has a path, then using:

$postdata = array('file[]' => "@/".realpath($file));

becomes:

Content-Disposition: form-data; name="file[]"; filename="/tmp/iy56ham"

and that path generated a BAD REQUEST. So I had to use chdir, basename and dirname in order to avoid using paths in the $postdata.

On the other hand, curl sent an extra header, not shown in the OP:

Expect: 100-continue

My web service didn't like it (neither twitter WS) and it answered with a:

417 Expectation Failed

To avoid curl sending that offending header you can use:

curl_setopt( $curlHandler, CURLOPT_HTTPHEADER, array('Expect:') );

so you set an empty Expect header and curl will not overwritten with 100-continue.

Hope this help someone...

Replace this line:

$postdata = array("file[]" => "@/".realpath($file));

with:

$postdata = array("file[]" => "@/".realpath($file).";type=video/mp4");

and it should work.
