For examle:
Your file is called movie.swf (wow, you wouldn't have guessed it). When you upload it, move it somewhere from where you can read it. This is done in form processing page.
Then from that page you can call out the template.php, which is the template I metnioned in previous post, and pass out the variable like (template.php?movie=movie.swf) i.e in the GET method and then on the template.php do the following:
instead $movie_name_from_db you will write $_GET['movie'].
That's one way.
Another is like this.
Perhaps you would like to go to the template page right after the form. In this case the basic processing thing should happen in the template.php page (like moving the uploaded file) and then calling out for the file from where it is placed in the parameter instead of $movie_name_from_db.
The first way I've mentioned is to save the swf file (or just the path to it) in the databse and then to read it in the template.php.
I hope this explains more...
