Altering the Page Array

Loading...

This video walks through how to use the new hook_page_alter() in Drupal 7 by transforming an unordered list into an ordered list. Because all of the content, region & blocks are stored within a renderable array before being output to the page, then this new hook allows modules and themes to make changes to page before it is fully rendered.
