Having trouble using the header() function

I want to setup 2 different pages that will be used for reading and downloading files.   I'm not sure on how to use the header function to differentiate from reading and downloading, or if there is a better way to do this then i'm for that as well.  The files will be a mixture of pdf files and msword files.  
What i'm getting the user to do is pick the file they want to read or download and then open it in the browser for reading if that is what they chose or open up a save box if they want to download.

Hopefully i've explained this well enough
thanks in advance

Have this in its own file in the folder you want to download from.
and the link is:
    /filename.php?f=fileToDL&t=TypeOfFileToDL

<?php
$apptype=$_GET["t"];
$dlFile=$_GET["f"];
header("Content-type: application/".$apptype);
header("Content-Disposition: attachment; filename=".$dlFile);
readfile($dlFile);
?>

Good luck and happy coding - the $_GET might not be right, I haven't had a chance to test the file since I learned of the removal of http_get_vars from php 5.0 so if you are not running that you can put that in and I know it will work.

Enjoy,

Thanks for the response Red010Knight


I just had a few more quick question for you if you don't mind... How do you get the filetype of a file again??? and is there any way to execute code after you download the file ?? I've tried to place just print commands afterwards but i get nothing unless the downloading fails.

Much appreciated red010knight

the filetype is basically the extension. Sometimes you can get away without it, but I like it just the same because sometimes browsers have conflicts dling files they know how to read.

so for your link if it is a word document the type is doc if it is a adobe acrobat it is pdf and so forth. That should help.

The best way to execute code afterwords is just have a :
header("Location: http://www.example.com/"); //will redirect the browser so that should help

But I haven't tried that before, as the issue never came up so my apologies for not being able to help with that.

and just goto that page...

Sorry I can't be more help in that regard,
