Total beginner with Magento... I've installed magento, and followed this article to the T. I have no issue with the article, it basically creates a custom admin menu item, and when you click on it you get a blank page.
I've gotten that far, but now I'd like to show something instead of the blank page. My end goal is to call some custom php code to show in the admin section when the custom admin menu item is clicked.
I'm a little lost on what the next steps are to achieve this goal. Do I need to setup templates / layouts for this, or is there a way to just route directly to my own custom php page? Are there any good tutorials for this? I've tried searching around but I'm not sure if I am using the right terminology etc.
I'm using the latest version of Magento. Thanks!
