#27888 (Feature request: `get_current_admin_url()` and `get_current_admin_hook()`) – WordPress Trac

It would be sweet if to be able to get the current page's url using some kind of API. And its hook, for that matter. For instance:

    public function get_current_admin_page_url()
    {
        if (!is_admin()) {
            return false;
        }
        global $pagenow;
        global $typenow;
        global $taxnow;
        global $plugin_page;
        $url = $pagenow;
        if (!empty($plugin_page)) {
            $url .= '?page='.$plugin_page;
        }
        elseif (!empty($typenow)) {
            $url .= '?post_type='.$typenow;
        }
        elseif (!empty($taxnow)) {
            $url .= '?taxonomy='.$taxnow;
        }
        return $url;
    }

And something similar for get_current_admin_hook().
