1. Drupal's content administration area lists all stories, pages and blog entries on the site.
2. A phpMyAdmin view shows the records in the node table of the Drupal database.
3. This php code does the work. It was written to query the database and send back the titles (as links) of all content created within a 28-day data range. The new module consists of this file and a few others. I used a tutorial on drupal.org as guidance. After testing, the module can be installed (and enabled and configured) on any Drupal site.
4. Page source code reviewed while testing. The query is sending back a series of node titles as links, as desired. The titles are in a div (id=block-onthisdate-0).
5. The div can be styled with CSS, and the new block can be placed on any page.
