AdminCP Upload Function

[Andrew]

I'm currently trying to update one of my clients custom hacks to work with vB3.5 however I am running into issues with this one last bit of code:

PHP Code:

    $vbulletin->input->clean_array_gpc('p', array(
            'imagefile' => TYPE_FILE
    ));
    
    $imagefile =& $vbulletin->input->clean_gpc('p', 'imagefile', TYPE_FILE);

    if (empty($imagefile)) { print_stop_message('please_complete_required_fields'); } 


It was originally using the globalize() function but after looking on vB.com I saw that I needed to use the clean_array_gpc() function instead. This method worked on the other portions of the hack but they were only sending strings and ints and not files. Any ideas on what I'm doing wrong ?
