To start with, your POSTFILEDS doesn't look correct. The single quote is not needed and the $filedir needs to be encoded.

You should do something like this,

$data = array(
            'MAX_FILE_SIZE'=>'33554432',
            'preview_area_id'=>'upload_file',
            'editor_area_id'=>'body',
            'js_function'=>'',
            'resource_id'=>'',
            'show_top_part'=>'no',
            'file_1'=>$filedir,
            'file_title_1'=>$filetitle,
            'file_desc_1'=>$filedesc);
$qs = http_build_query($data);

And use $qs as POSTFIELDS.
