Unable to upload an image to a folder from a custom backoffice controller

[prak]

Hello, I want to upload an image from the backoffice, into a folder named uploads in the root directory of the module. Here is my code:

  <form action="/modules/customizeproducts/upload.php" enctype="multipart/form-data" method="POST">
      <input type="hidden" name="MAX_FILE_SIZE" value="30000" />
      Send this file: <input name="userfile" type="file" />
      <input type="submit" value="Send File" />
 </form>

my upload.php file:

$uploaddir = 'uploads/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile);
echo '<pre>';
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
    echo "File is valid, and was successfully uploaded.\n";
} else {
    echo "Possible file upload attack!\n";
}

echo 'Here is some more debugging info:';
print_r($_FILES);

print "</pre>";

Help would be greatly appreciated!!!!

Turns out that it was a size issue that prevented me from uploading some images. I increased the maximum size and removed the "move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile);" from above the echo function. It was causing the error message to display always.
