 I was looking for a way to get the parent ID of the current subpage recently and could not find an available function on the codex pages. I needed this function in order to create a navigation that is always based on the current page. The site I was working on has no more than 3 levels of navigation, so I needed a way for the deepest sub-pages to generate the same side navigation as the 2nd level pages. I wrote this short simple function.

Hopefully someone may find it usefull.

//Gets the parent ID of a post or page
function get_parent($parent) {
global $wp_query;
$return = $wp_query->post->post_parent;

return $return;
}
