I build a BLOCK that sits on a right side of the website and is available for whole site.
Also I got a many CONTENT_TYPE NODES like (pages, news,gallery, files).
How can I modify _preprocess_xxxxx and which one, so I can let my BLOCK know which CONTENT_TYPE is currently displaying.
so then my BLOCK displays var $section = top 10 download for CONTENT_TYPE==files;
and for CONTENT_TYPE==news, I will see latest news in my block var $section.
etc, etc...
