invisible element

I have a sign-up form with multiple boxes. The customer will put their username in a text box. After they submit the form they will be taken to a payment screen. On this payment screen there is a text box and an add to cart buttom for adding products to their cart. (this is done via paypal. My question is, I need the text box on the second page to automaticly fill in the member name they put in on the first screen, and make it invisible. Is there anyway to do this? Thanks for your help

A hidden textbox in HTML can be made by including a tag like this inside the form field:

<input type=hidden name="memname" value="John Netherfarm">

So if you are using a PHP-script to generate the second page, in that script you will need to write

echo '<input type=hidden name="memname" value="'.$_POST['membername'].'">';

That is assuming that the member name input field on the first page is

<input name="membername" value="">

and that the form field uses POST method.
On the second page, a tag like the first one in this post will be printed.

I hope that helps!
