FDF - Open PDF Problem

[savagenoob]

I can create the file using the PDF template, but cant open the FDF file. When you open the FDF it actually opens the PDF template with the data filled it, and when I try to open this with the script it says it cannot find the file and I assume it is talking about the PDF template...

How do I modify this to open the PDF with the FDF data....

<?php
$data['date']=date('Y-m-d H:i:s');                        
require_once 'createFDF.php';                                    
$fdf_file=time().'.fdf';              
$fdf_dir=dirname(__FILE__).'/Forms'; 
$pdf_doc='/BrokerAgreement.pdf';           
$fdf_data=createFDF($pdf_doc,$data);             
if($fp=fopen($fdf_dir.'/'.$fdf_file,'w')){                
fwrite($fp,$fdf_data,strlen($fdf_data));                
echo $fdf_file,' written successfully.';
header("Content-Disposition: attachment; filename=$fdf_file");
Header("Content-type: application/pdf");
$fd = fopen($fdf_dir.'/'.$fdf_file , "r");
   fpassthru($fd);
   unlink($fdf_file);
?>

No one knows how to open an FDF file after its been created? I really need to figure this out...
