I have a wordpress blog, with an iframe included in sidebar.php. I have some wordpress specific code inside of this iframe, and it does not seem to "interact" with the rest of the wordpress code. Is it normal? Is there any way to get around this one?
The purpose of an iframe is to have a different "webpage" inside a box on another page. If they are related it is either because you make it so on the server, or either in your mind. For the browser and the server as such: they are 2 independent requests.
So the question you probably should pose yourself is : why did I use an iframe ?
