form help please

[lupes]

Hi, im trying to make this thing where once a user submits their information, they can download this zip file.

But i want the form to first submit, and then for the download to begin.

i can make the form on its own, but can anyone please tell me how i can make the download begin only after the form has been sent?

Thanks.

DO this:
[code=php:0]if(isset($_POST['submit']))
{
  // perform download
}
else
{
    // show form
}[/code]
