You can get the sidebar properties using this variable. global $wp_registered_sidebars; if ( isset( $wp_registered_sidebars[‘sidebar-2’] ) ) { echo $wp_registered_sidebars[‘sidebar-2’][‘name’]; } Note that do not use it too early, either on/after widgets_init hook or in a template file.

Then we clean up in two ways: First we remove our wp_trim_words() filter, if it’s running, before the current widget is displayed. We can do that by … Read more

The built-in dashboard widgets are not marked somehow, you have to use a fixed list: ‘dashboard_right_now’, ‘dashboard_plugins’, ‘dashboard_quick_press’, ‘dashboard_recent_drafts’, ‘dashboard_recent_comments’, ‘dashboard_incoming_links’, ‘dashboard_primary’, ‘dashboard_secondary’ So your code should test if the current widget is in that list and remove the widget, if it isn’t: add_action( ‘wp_dashboard_setup’, ‘t5_remove_custom_dashboard_widgets’, 11 ); function t5_remove_custom_dashboard_widgets() { global $wp_meta_boxes; $builtin = … Read more
