To point out the obvious, you can pass variables to any URL by using GET: <iframe src="page.php?var1=foo&var2=bah"></iframe> iframes can be targeted with links just like a regular frame, using target="frameName" Other options would be to have variables stored in sessions, in cookies, or via POST variables (I think). But (to the best of my knowledge), since PHP is server-side, these pretty much all rely on reading/acting on the variables whilst the page is being processed and sent by the server. I get the feeling you perhaps want to have an existing page in an existing iframe react in relation to things happening elsewhere... correct? I don't think it REALLY can, since once the frame's content is server-side, it has nothing to do with PHP. You basically need to force the frame's contents to refresh, perhaps with new variables passed in with either GET, POST, sessions or Cookies. Javascript can read cookies, but I don't think this is your answer at all. You need to be more specific about what you want to achieve. Justin
