I can hardly understand what you are saying, here is help for what I can read. Iframes are a HTML issue, they have nothing to do with PHP. And to send data from one Iframe to another requires javascript as far as I know.

You would probably be better to use ajax to update the content. With ajax you can update the content in a div dynamically. Iframes are messy and probably should be avoided unless you have to use them.

Also, if you want anyone to put any real time into helping you, you should put a little more time into making your posts in decent English.
