For passing back values to PHP you need a script that does 2 things:

- Ask for the email address
- Handle the address with PHP

Because PHP will not wait for a user to put in it's e-mail address,
these are two separate pieces of code.

You can do this for example by checking if the email address has
been entered:

<?php // myscript.phtml

        if ($email)
                // Part 1
        } else
                // Part 2

Part 1 handles the email address the way you want

Part 2 can be done in a number of ways, as long as the e-mail address
gets entered and send back to the script.

A simple way is using a form:

<FORM ACTION="myscript.phtml">

But you could also use JavaScript to create a dialog
and 'redirect' to your script, passing the email address
in the URL, probably something like:

  email = prompt("Please enter your address");
  document.window.location.href = "myscript.phtml?email=" + escape(email);
