PDF Comments? Can they be included?

[MikeNye]

Hi all,

I have a script that calls and displays PDFs from a folder either as single or compiled into a book.

The problem I have is that the original PDFs have comments attatched, when PHP processes them it loses the comment information? Anyone know how I can retain this?

heres my script;

header("content-type: application/pdf");
$userid=$_GET['uid'];
$filename=buildPdfFromCart($userid);
$fh = fopen($filename,'r');
$data = fread($fh,filesize($filename));
print ($data);

function buildPdfFromCart($userid){
global $theDb;
$items=sql("select from cart where userid=".$userid." order by id");
if ((mysql_affected_rows($theDb)>0) ){
while($itemRecord=mysql_fetch_array($items)){
$country=$itemRecord["country"];
$airfield=$itemRecord["airfield"];
$plate=$itemRecord["plate"];
$source=$itemRecord["source"];
if($plate==(integer)-50){
//its a user defined product - so get all the items in this product - they can be either plates or booklets
//country holds the product id
$myproductid=$itemRecord["country"];
$strSQL="select from myproductitems where myProductId=$myproductid order by id";
$productData=sql($strSQL);
while($itemRecord=mysql_fetch_array($productData)){
$country=$itemRecord["country"];
$airfield=$itemRecord["airfield"];
$plate=$itemRecord["chart"];
$source=$itemRecord["source"];
if($plate==(integer)-99){
//The airfield booklet has been selected - loop through airfield and add all plates
$strSQL="select hy_title from hybrid_charts where hy_country=\"$country\" and hy_airfield=\"$airfield\" order by hy_title";
$plateLink=sql($strSQL);
while($plateData=mysql_fetch_array($plateLink)){
//echo getPlateFilename($country,$airfield,$plateData['chart'],$source)."<br/>";
$platesArry[]= trim(getPlateFilename($country,$airfield,$plateData['hy_title'],$source));
}
}
else{
//echo "'$country','$airfield','$plate','$source'"."$".trim(getPlateFilename($country,$airfield,$plate,$source)).".pdf$<br>";
$platesArry[]= trim(getPlateFilename($country,$airfield,$plate,$source))."";
}
}

        }else{
           if($plate==(integer)-99){
              //The airfield booklet has been selected - loop through airfield and add all plates
              $strSQL="select hy_title from hybrid_charts where hy_country=\"$country\" and hy_airfield=\"$airfield\" order by hy_title";
              $plateLink=sql($strSQL);
              while($plateData=mysql_fetch_array($plateLink)){
                 //echo getPlateFilename($country,$airfield,$plateData['hy_title'],$source)."<br/>";
                 $platesArry[]= trim(getPlateFilename($country,$airfield,$plateData['hy_title'],$source));
              }
           }
           else{
              //echo trim(getPlateFilename($country,$airfield,$plate)).".pdf<br>";
              $platesArry[]= trim(getPlateFilename($country,$airfield,$plate,$source))."";
           }
        }
     }
   }else{
  }
  $pdf =& new concat_pdf('P','mm','A5');
  //print_r($platesArry);
  $pdf->setFiles($platesArry);
  $pdf->concat();
  $filename="./outputCharts/test_".$userid.".pdf";
  $pdf->Output($filename, 'F');

  //Now delete the cart and copy the current contents to the history table
  $strSQL="delete from cart where userid=$userid";
  sql($strSQL);

  return $filename;

If anyone could help it would be greatly appreciated as im hitting a blank...and im under a bit of pressure to get this working...as we all are 😃

Any help or advice would be more than greatly welcomed.

thanks
Mike
