force php script exection from headers

[crafter]

I wish for the client to click on a link that will run a php script and then do a forced download. I can easily do this if I make the client have to click on two links
(link 1 to create jpg from php script, link 2 to download the jpg file).
I wish to do so with just one link though.

My php script to force download is here:

<?php
header("Content-type:application/jpg");
header("Content-Disposition:attachment;filename=bobo.jpg");
readfile('bobo.jpg');
?>

This works, but I want this same php script to force the execution of another php script (the one that creates the bobo.jpg).

Please Help!
Thanks,
Doug

use a link to the same file you're in, and the link looks like:

http://www.yoursite.com/something.php?c=1

<php
if(!empty($_GET["c"]))
{
header("Content-type:application/jpg");
header("Content-Disposition:attachment;filename=bobo.jpg");
readfile('bobo.jpg');
die();
}

And other contents comes here.

So a separate PHP script generates the image? Why not something as simple as:

<?php

include 'some_other_script.php'; // script that creates image

// now add the rest of the code you have already
?>
