Dynamic, Expanding Forms with PHP?

[Trent_Hatred]

I've found an example of something done in Javascript, and was wondering if it can be done using PHP (or modified to work with PHP).

Here's the link:

What it does is create a form which allows you to enter items. Once you press "Add Item", a new form row appears allowing you to add another item.

I need to build this functionality into an order processing system to allow you to add items to a purchase order.

I'm hoping someone out there has an idea/tip/example of such a system.

Thanks much,

This is primarily simple process.

Create a table to store purchase order information but not the products for it.

Create a table for the added items such as the products and have a field that matches the POs id number

Example:
PO table fields - poID, poTitle, poDescription, etc.
Item table fields - itemID, poID, itemName, etc.

In your POs list that will display on your page, create a link to the add items page with the poID in the URL. Have a hidden tag in the following pages form for holding the poID.

This will tie the 2 tables together by referencing the POs id number.

I have built 2 of these sysytems and use the same method. Each system is different based on the clients requirements, but the method is basically the same.
