PowenKo, WordPress Tutorial 30-2, category, get all categories hierchy

GET TOP PARENT CATEGORY (WORDPRESS),

There are many times when you need to show or get the top most (root) parent category in WordPress – regardless of how many subcategories you might be deep. I have used this logic for page navigation (highlight the top parent tab) – as well as within some custom loops/sidebar code.

They way to do this:

<?php

function get_cat_hierchy($parent,$args){

	$cats = get_categories($args);
	$ret = new stdClass;

	foreach($cats as $cat){
		if($cat->parent==$parent){
			$id = $cat->cat_ID;

			$ret->$id = $cat;
			$ret->$id->children = get_cat_hierchy($id,$args);
		}
	}

	return $ret;
}
$args = array(
		'type'                     => 'post',
		'child_of'                 => 0,
		'hide_empty'               => false,
		'hierarchical'             => true,
		'exclude'                  => '1'
	);
$retarray=get_cat_hierchy(0,$args);
print_r($retarray);
echo "<p><p><p><p>";
/?>
