Is it possible to create a PHP page that would have a test box with different buttons (much like that of this reply box), and then a few other buttons that would say "Show HTML" and "Show PHP". What I want is the page with the text box and stuff, to be in one place, but when you click "submit" or whatever, it will edit a section of code (maybe an iframe or something) in another page. So it would edit the content of another page... Is this possible?
