    Basic Example

    If added to a child theme’s functions.php file, this will remove the footer sidebars registered by the TwentyTen theme.

    function remove_some_widgets(){
    	// Unregister some of the TwentyTen sidebars
    	unregister_sidebar( 'first-footer-widget-area' );
    	unregister_sidebar( 'second-footer-widget-area' );
    	unregister_sidebar( 'third-footer-widget-area' );
    	unregister_sidebar( 'fourth-footer-widget-area' );
    add_action( 'widgets_init', 'remove_some_widgets', 11 );


    In the example, note that we assign a priority of 11 when registering the widgets_init hook. This is because a child theme’s functions.php file is called before the parent theme’s, which means that our call to unregister_sidebar() would accomplish nothing since the sidebar has not yet been registered.

    By lowering the priority of our action, we ensure that it is called after the parent theme’s functions.php file is loaded.
