Get Hierarchal list of categories?

  • Is there a function to get a hierarchal list of a categories children/grandchildren/greatgrandchildren?

    For example, let’s say I have the categories like Things > Living Things > Animals > Cows, Pigs, Sheep

  • Hi Oguruma,

    sure:

    1. Just go to Post -> Add New Category -> Creat Parent Category
    2. Go to Post -> Add new category -> choose Parent Category in the Dropdown

    And so on…

    <?php
	hierarchical_category_tree_09hy7( 0 ); // the function call; 0 for all categories; or cat ID  
	function hierarchical_category_tree_09hy7( $cat ) {
		$next = get_categories('hide_empty=0&orderby=name&order=ASC&parent=' . $cat);
		if( $next ){   
			foreach( $next as $cat ){
				echo '<ul><li>' . $cat->name . '';
				hierarchical_category_tree_09hy7( $cat->term_id );
			}	
		}
		echo '</li></ul>'; echo "\n";
	}  
?>

    seems to work on my localhost. Note the hide_empty=0 I’m using locally so it shows all even empty categories.
