php query string in an iframe

[cdj]

Is it possible to include a php query string in an iframe on vbulletin? Essentially I'm trying to embed a php page into an article/static page and be able to call variables from it. Here's what I'm trying to set the src as for the iframe.

or

If I hardcode the channel name into the php and then put it into an iframe, everything works fine but when I change it to

PHP Code:

$_GET['channel'] 


and pass the variable, it renders a blank page in the iframe.

Am I going about this all wrong? I read this guide a bit but since I'm not a developer, I'm not sure if that's the route I need to go.


I'll readily admit that I'm not that savvy when it comes to development. I can tweak and modify something that someone else built but I certainly can't build something form scratch. That said, I was rather proud of me dissecting the Twitch API to be add extra elements that weren't originally included where I copied this code from. I'm hoping to be able to show them off dynamically.
