Fairly simple way to match sidebar content with the main content for several pages without the need to create multiple blocks or the hassle of putting content in a block.

For example, your Home, About and Contact pages all have a sidebar with some accompanying content which is different for each.

   1. Create pages (nodes) for each of the sidebar content and note the node ID.
   2. Add a block and paste in this code snippet
   3. Edit the Switch/Case part of this snippet for your nodes
   4. Enable the block for content/* and node/*
