POST with curl

[ziycon]

I'm wondering if anyone can tell me where I'm going wrong here trying to post with curl?

$url = 'https://mysite.com/submit';
$prefix = '-----';
$boundary = rand(1000000000,9999999999);
$fields_string = '';
 
$fields = array(
    'chan'=>urlencode($_POST['chan']),
    'redirect'=>urlencode($_POST['redirect']),
    'file1'=>@$_FILES['file1'],
    'file2'=>@$_FILES['file2']
);
 
$contentType = "multipart/form-data; boundary=".$boundary;
foreach($fields as $key=>$value) {
    $fields_string .= $prefix.$boundary.'\r\n
    Content-Disposition: form-data; name="'.$key.'"\r\n\r\n
    '.$value.'\r\n';
}
$fields_string .= '\r\n'.$prefix.$boundary.'--';
 
print $fields_string."<br/>";
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_ENCODING, $contentType);
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields_string);
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
if(!curl_exec($ch))    {
    trigger_error(curl_error($ch));
} 
curl_close($ch);
