Steps to build a default theme
implementation
Okay, now it's time to exorcise our lazy-developer habit and practice building
our own theme hook. From Chapter 3, you should recall that we'll need to do the
following things:
1. Register the theme hook and define default variables.
2. Build the default implementation of our theme hook.
3. Re-build the theme registry.
4. Build a render element to use the theme hook.
Our current implementation of the Recent blog posts block simply shows a list of
blog titles. But it would be nice to include the date of each post, as well as the author
(if we have multiple people creating posts). So in this third and final version of our
module, we're going to create a single-blog-block-item.tpl.php to render the
contents of each item in our list of blog posts. By convention in Drupal, any CSS,
JavaScript, or template files needed by a module should use dashes instead
of underscores in their filenames.
