PHP Upload Issue

[TheMayhem]

I have a file that I am working on for an Admin CP upload of an image. I'm running into a problem on trying to get it to successfully upload the file. Here is my coding:

PHP Code:

    $vbulletin->input->clean_array_gpc('p', array(
        'name'             => TYPE_STR,
        'url'               => TYPE_STR,
        'description'      => TYPE_STR,
        'type'             => TYPE_INT,
        'enable'           => TYPE_INT,
    ));

    $vbulletin->input->clean_gpc('f', 'image', TYPE_FILE);

     if ($vbulletin->GPC['image'] == '')
    {
        print_stop_message('adright_no_image');
    }

    $dir = dirname(__FILE__);
    $dir .= "/adright/";

    if (!is_dir($dir)) {
        print_stop_message('adright_bad_directory');
    } else {
    $new_file =  $dir .  basename($vbulletin->GPC['image']['name']);
    print $new_file;
    if (!move_uploaded_file($vbulletin->GPC['image']['tmp_name'], $new_file)) {
        die('An error has occurred<br />' . $vbulletin->GPC['image']['error']);
    }
    } 


The only output I ever get is An error has occurred. The file is never uploaded and it doesn't seem to be grabbing my image file correctly for the upload process. I know the upload image form is working because I never visibly see the phrase related to not entering an image. Any help on where I am going wrong would be greatly appreciated.
