Uploading a file to a remote server, help!!

[ravinghatmaker]

Hi, I'm trying to upload a file to a remote server where the following variables also have to be passed:

 

key = special md5 key based on the time

name = name of file

data = data of the file being uploaded.

 

The problem is that the remote server doesn't seem to be accepting these variables when I send them.  My code is made up of large part of code that was posted on php.net under fsockopen entry, but I've gone through it a million times and I still don't quite know what I'm doing wrong.  I have a feeling there is something easy I am missing.  Can anyone with any experience please take a look at this for me?

 

On the form page before this, I just have a simple form with this code:

 

<form enctype="multipart/form-data" action="uploadprocess.php" name="uploadvideo" method="POST">

Please choose a file: <input name="data" type="file"  /><br />
<input name="submit" type="Submit" value="Upload" />

</form>

 

and the uploadprocess.php file is:

 

<?

$api_key = '*******'; //This is my special key for md5
$keyvalue = md5(date("YmdHis") . $api_key);
$keyvalue .= date("YmdHis") . "***"; //*** is my member ID number

$file_name = $_FILES['data']['name'];
$tmp_name = $_FILES['data']['tmp_name'];
$content_type = $_FILES['data']['type'];

srand((double)microtime()*1000000);
$boundary = "---------------------".substr(md5(rand(0,32000)),0,10);
       
// Build the header
$header = "POST /api.php HTTP/1.0\r\n";
$header .= "Host: api.site.net\r\n";
$header .= "Content-type: multipart/form-data, boundary=$boundary\r\n";
// attach post vars

$data .="--$boundary\r\n";
$data .= "Content-Disposition: form-data; name=\"key\"\r\n";
$data .= "\r\n".$keyvalue."\r\n";
$data .="--$boundary\r\n";

$data .="--$boundary\r\n";
$data .= "Content-Disposition: form-data; name=\"name\"\r\n";
$data .= "\r\n".$file_name."\r\n";
$data .="--$boundary\r\n";
// and attach the file
$data .= "--$boundary\r\n";
$content_file .= join("", file($tmp_name));

$data .="Content-Disposition: form-data; name=\"data\"; filename=\"$file_name\"\r\n";
$data .= "Content-Type: $content_type\r\n\r\n";
$data .= "Content-Transfer-Encoding: binary\r\n\r\n";
$data .= "".$content_file."\r\n";
$data .="--$boundary--\r\n";
$header .= "Content-length: " . strlen($data) . "\r\n\r\n";
// Open the connection
$fp = fsockopen("api.site.net", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
// then just
fputs($fp, $header.$data);

while (!feof($fp))
	$http_dmy .= fgets($fp, 4096);
	fclose($fp);

}
