Question

I am using this curl script to try to upload user selected files by FTP. It uploads the files to the server but they are all blank. Why is this happening?

if (!empty($_FILES['userfile']['name'])) {
    $ch = curl_init();
    $localfile = $_FILES['upload']['tmp_name'];
    $fp = fopen($localfile, 'r');
    curl_setopt($ch, CURLOPT_URL, 'ftp-addy-here'.$_FILES['userfile']['name']);
    curl_setopt($ch, CURLOPT_UPLOAD, 1);
    curl_setopt($ch, CURLOPT_INFILE, $fp);
    curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localfile));
    curl_exec ($ch);
    $error_no = curl_errno($ch);
    curl_close ($ch);
        if ($error_no == 0) {
            $error = 'File uploaded succesfully.';
        } else {
            $error = 'File upload error.';
        }
 } else {
        $error = 'Please select a file.';
 }

echo $error;

Line 3, right now it says:

$localfile = $_FILES['upload']['tmp_name'];

Change it to:

$localfile = $_FILES['userfile']['tmp_name'];
