Reproducing hierarchical list output from wp_list_categories(), using get_categories()

by

I need more control over the category listing output, so I’m using get_categories(), instead of wp_list_categories().

This function returns a flat array of objects ordered by a certain attribute. How can I build a hierarchical list from it like wp_list_categories() does?

The most ideal solution for walking over the data is to use the WordPress walker class.

You won’t find many an example around the web for using it, but one was given by Scribu here.

You can also look to the classes WordPress uses to extend the walker as further examples.

Hope that helps..
