[SOLVED] File extension not shown on downloads

[Mutley]

I use the following to get files off the server as downloads...

 

$file = spreadsheet.xls;

 

It popsup as an Unknown file? It seems with Microsoft Office documents it does this but I've tried PDF and PSD and they display fine and open with the correct application.

 

		header('Content-Description: File Transfer');
	header('Content-Type: application/octet-stream');
	header('Content-Disposition: attachment; filename='.basename($file));
	header('Content-Transfer-Encoding: binary');
	header('Expires: 0');
	header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
	header('Pragma: public');
	header('Content-Length: ' . filesize($file));
	ob_clean();
	flush();
	readfile($file);
	exit;		

 

Any ideas?

 

Thanks,

Nick.

does the downloaded file have the extension .xls ?

if so then its a problem on the client (downloaders) PC  ie office not installed

There is no extension. Which is odd, as PDF/PSD works fine.

 

Office is installed on the machine.

[MadTechie]

in that case your need to check where your getting $file from

as its $file = "spreadsheet"; not $file = "spreadsheet.xls";

It echos the extension.

 

It says on the Save As popup: application/octet-stream

 

As I said, it picks up the .PSD or .PDF file extensions fine.

Try this, if it fails then you could uncomment the 2 commented lines

 

      ini_set('zlib.output_compression','Off'); 
      header('Content-Description: File Transfer');
      header('Content-Type: application/octet-stream');
      header('Content-Disposition: attachment; filename="'.basename($file).'"');
      header('Content-Transfer-Encoding: binary');
      header('Expires: 0');
      header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
      header('Pragma: public');
      header('Content-Length: ' . filesize($file));
      #header('Content-Type: application/vnd.ms-excel;');
      #header("Content-Type: application/x-msexcel");

      ob_clean();
      flush();
      readfile($file);
      exit;

Thanks alot! That worked! Do you know why?

Add the quotes to the file time, may of worked

but by telling the browser the Content-Type should work
