I am working with Drupal 7.17.
I have a custom content type I created called Sidebar Ad (machine name sidebar_ad) that I want to add Javascript and PHP to. From what I understand, in the templates directory of the theme I am working with, I need to create a file called 'page--sidebar_ad.tpl.php' and I can put PHP and Javascript code in there, and it will only run in blocks and pages that contain the custom content type Sidebar Ad.
I am trying this out with one of the stock themes, Bartik, and it is not working for me. I tried it by copying the page.tpl.php file, renaming it page--sidebar_ad.tpl.php, and adding a bit of text in a few places - at the top of the php file, and in the content div. But I don't see anything change on the pages on my site that contain that custom content type.
Is there something I am missing?
