How to hide empty categories automatically?

[simon1066]

Works great on ver 1.5.6a

And on ZC v1.5.6c

I've spent a while trying to also hide empty categories in my menu that uses the 'categories_ul_generator' class, this code:

require_once (DIR_WS_CLASSES . 'categories_ul_generator.php');
$zen_CategoriesUL = new zen_categories_ul_generator;
$menulist = $zen_CategoriesUL->buildTree(true);
$menulist = str_replace('"level4"','"level5"',$menulist);
$menulist = str_replace('"level3"','"level4"',$menulist);
$menulist = str_replace('"level2"','"level3"',$menulist);
$menulist = str_replace('"level1"','"level2"',$menulist);
$menulist = str_replace('<li>','<li>',$menulist);
$menulist = str_replace("</li>\n</ul>\n</li>\n</ul>\n","</li>\n</ul>\n",$menulist);
echo $menulist;} 

Thought I would post the solution:

/includes/classes/categories_ul_generator.php

$categories = $db->Execute($categories_query);
         while (!$categories->EOF) {
			// skip empty or status off categories
			if (!(CATEGORIES_PRODUCTS_INACTIVE_HIDE == 1 && zen_count_products_in_category((int)$categories->fields['categories_id']) == 0)) {
            $this->data[$categories->fields['parent_id']][$categories->fields['categories_id']] = array('name' => $categories->fields['categories_name'], 'count' => 0);
			}
            $categories->MoveNext();
        }

I was going off Ajeh's /includes/classes/site_map.php as a guide - it looks as though there might be an additional change needed in categories_ul_generator.php, looking in to it.
