CURL uploads blank file by FTP

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'];

You didn't check if the initial file upload succeeded. Checking for the presence of the remote filename is NOT an indication that it got uploaded. The 100% reliable method to ensure the upload worked is

if ($_FILES['userfile']['error'] === UPLOAD_ERR_OK) {
  ... ftp stuff ...
} else {
    die("Upload failed with error code: {$_FILES['userfile']['error']}");
}

The codes/constants are documented here: http://php.net/manual/en/features.file-upload.errors.php
