The description of your problem is very minimal but the obvious solution is simply to output widget data only when the query is not empty: class cond_widget extends WP_Widget { public function __construct() { // widget actual processes parent::__construct( ‘test’, // Base ID ‘test’, // Name array( ‘description’ => __( ‘test’, ‘foo’)) ); } public … Read more
This is quite easy using the sidebars_widget filter. What we want to do is, in the back end, add our three widgets in the desired sidebar where we need them. This will, as always, display all the widgets in the order they appear in the backend in the sidebar. If you only need this on … Read more
