update one web page from another

[haskins]

I want to find a way to update several pieces of information in a web page from a form on another webpage.(both on the same server).

Any ideas?

you need server-side programming

Assuming both document are open in different windows, and the first window opened the second, the second window can communicate information back to the first:

window.opener.document .... etc
