Add Custom Layout Handles (e.g. Parent Categories)
If you ever need custom layout handles in your local.xml, it's fairly simple. In this example the observer method will make a new handle for for categories that have children or not, but you can just modify the method to make whatever handles you desire. (I realized after creating this there's already a handle for anchored categories with no subcategories, catalog_category_layered_nochildren)
First add this to your config.xml in yourcustommodule:
<config> <frontend> <events> <controller_action_layout_load_before> <observers> <yourcustomtheme_observer> <class>yourcustomtheme/observer</class> <method>addHandles</method> </yourcustomtheme_observer> </observers> </controller_action_layout_load_before> </events> </frontend> </config>
Then add this method to your observer:
class YourPackage_YourCustomTheme_Model_Observer extends CLS_Core_Model_Abstract { public function addHandles($observer) { $category = Mage::registry('current_category'); if ($category instanceof Mage_Catalog_Model_Category) { $update = Mage::getSingleton('core/layout')->getUpdate(); $fertilility = (count($category->getChildrenCategories()->getData())) ? 'parent' : 'nochildren'; $update->addHandle('catalog_category_' . $fertilility); } return $this; } }

I think
$fertilility = ($category->getChildrenCategories()->count()) ? 'parent' : 'nochildren';might work. If so, it'd be better to do it that way probably.Nice idea with the slug.

Nice idea! One bug though (in 1.5 at least): drop the ->getData() call. Just call it like this:
$fertilility = (count($category->getChildrenCategories())) ? 'parent' : 'nochildren';
An enhancement I made as well was to add another handle for specific categories:
if($slug = $category->getUrlKey()) {
$update->addHandle('catalog_category_' . $slug);
}
