Well by the time you are talking about PHP is out of the picture. PHP can be used to
generate a DOM but once its generated PHP (or any server side language) is out of the
picture, it then goes to the client-side stuff like you said. You can use PHP's
fopen() to grab the page and then add the form and hidden fields I was talking about.
By doing this, you are setting up the page to be handled correctly by the Javascript
code you inserted through PHP.
