List Links to Posts by Category

The code below will list links to posts grouped by the category of the post.  It was developed for WP 2.9’s  default theme.

See the Codex for the Function get_terms() for documentation of the arguments that can be used to alter the terms selected.


<?php
/**
 * @package WordPress
 * @subpackage Default_Theme
 */
/*

<?php get_header(); ?>
<div id="content" role="main">

<?php
$hide_empty = true;
$hierarchical = true;
$args = array(

    This code is a sample Template. Copy it to your theme’s folder with a name like ‘listbycategory.php’. Create a new Page (not Post) and assign it as the Template. It is written for the WP Default theme, so you will need to modify it for your theme.
