Displaying taxonomy filters hierarchically

I thought I would add to this as I think my question adds to this. Is it possible to manually sort a taxonomy? Currently it just lists the taxonomy terms alphabetically.

I made the category drop-down hierarchical, with counts for categories and tags, with these mods to template.php:

Look for:
# Taxonomy dropdown:

Replace the $terms = get_terms… with:

$terms = get_terms( $key, array(
	'hide_empty' => true,
	'pad_counts' => true
) );
sort_terms_hierarchy($terms);

Then add this sort_terms_hierarchy function somewhere:

function sort_terms_hierarchy(Array &$terms) {
	$result = array();
	$parent = 0;
	$depth = 0;
	$i = 0;
	do {
		$temp = array();
		foreach($terms as $j => $term) {
			if ($term->parent == $parent) {
				$term->depth = $depth;
				$term->name = str_repeat('?',$depth*4).$term->name.' ('.$term->count.')';
				array_push($temp, $term);
				unset($terms[$j]);
			}
		}
		array_splice($result, $i, 0, $temp);
		$parent = $result[$i]->term_id;
		$depth = $result[$i]->depth + 1;
	} while ($i++ < count($result));
	$terms = $result;
}

Hope somebody can help me out here – I tried tbird12’s solution & it works fine! (thank you very much!)

What I wanted to do is to indent the sub-taxonomies down the list, like:

tax_1
– sub_1
– sub_2
tax2
– sub_3
…

(and btw: that should be a feature!)
so I started playing around with it. this almost did the job:

function sort_terms_hierarchy(Array &$terms) {
	$result = array();
	$parent = 0;
	$depth = 0;
	$i = 0;
	do {
		$temp = array();
		foreach($terms as $j => $term) {
			if ($term->parent == $parent) {
				$term->depth = $depth;
				$term->name = str_repeat(' ',$depth).$term->name.' ('.$term->count.')';
				array_push($temp, $term);
				unset($terms[$j]);
			}
			elseif ($term->parent != $parent) {
				$term->name = ('- ').$term->name;
			}
		}
		array_splice($result, $i, 0, $temp);
		$parent = $result[$i]->term_id;
		$depth = $result[$i]->depth + 1;
	} while ($i++ < count($result));
	$terms = $result;
}

… the only flaw is that with every taxonomy down the list, it will add 4 more – – – – to every sub-tax;
(moving the array_push and the unset underneath my elseif will lead to the desired layout, but the items will be sorted alphabetically again)

– what am I missing? any suggestion is appreciated!

and yes, my php is very basic indeed ??

Ted,

Whatever character you want for the indent, put in place of the ‘ ‘ in this line in my code:
$term->name = str_repeat(‘ ‘,$depth*4).$term->name.’ (‘.$term->count.’)’;

If you want a dash, use:
$term->name = str_repeat(‘-‘,$depth*4).$term->name.’ (‘.$term->count.’)’;

oh wow, I didnt expect such a quick response - im flabbergasted, thank you so much!

if I insert an &nbsp it looks well organized already (so I could live with that), but if I insert a dash it still gets repeated 4 times (but doesnt stack anymore) can you tell me whats the reason for that?

Does this do what you want?:

$term->name = str_repeat('- ',$depth).$term->name.' ('.$term->count.')';

But, that won’t work if you have sub-sub cats, where you just want one dash even when a cat is 2 or more deep.

Oh! My original code should have &-n-b-s-p-; where it shows a space. But, it doesn’t show. I just noticed that.

perfect! that did the trick, thank you so much!
