How to open and count a PDF-File

Hi,

I want to open different PDF Files while counting the opening process.

I would like send an email, once a specific PDF opens. (Simple.) I do have the problem though that I don't seem to get it opened:

The help-file might be opened with an URL like redirect.php?id=123456

<?php
$id = $_REQUEST['id'];

// The PDF File with the number as the name is stored in a folder.

$pdf_file = "folder/".$id.".pdf";

//If I open the header like this:
header("Location: http://www.url.com/.$pdf_file");

//it doesn't work.

//If I do

header('Content-type: application/pdf');
readfile($file);

//it doesn't work either.

How can I open a pdf-document using PHP?

Please help me out here. Thank you very much.

//If I open the header like this:
header("Location: http://www.url.com/.$pdf_file");

The dot between the / and $pdf_file should not be there. If that is not the problem, are you getting any error messages like "headers already sent"?

Hi,

no, I don't get any message at all. It doesn't show anything and nothing happens. Do you know another solution for the opening of PDF-Files?

Thank you,
Kelley
