Extending WordPress With Custom Content Types — by Brian Onorio

One of the best attributes of WordPress is its ease of use. It’s easy because there’s not a significant amount of bloat with endless bells and whistles that steepen the learning curve. On the flip side, some might find WordPress a little... well, light. It does a lot, but not quite enough. If you find yourself hacking WordPress to do the things you wish it would do, then the chances are high that this article is for you.

WordPress can be easily extended to fit the requirements of a custom data architecture. We’re going to explore the process of registering new data types in a fully compliant manner.

Excerpt From Chapter 4

Customizing Tree-Like Data Structures In WordPress With The Walker Class — by Carlo Daniele

In WordPress, a navigation menu, a list of categories or pages, and a list of comments all share one common characteristic: They are the visual representation of tree-like data structures. This means that a relationship of superordination and subordination exists among the elements of each data tree.

There will be elements that are parents of other elements and, conversely, elements that are children of other elements. A reply to a comment depends logically on its parent, in the same way that a submenu item depends logically on the root element of the tree (or subtree).
