Hello Everyone, In this blog I teach you How to remove parent widget and sidebar in child theme wordpress. Below code is the parent theme sidebar code.

class PWidgetName extends WP-Widget {
    // your widget code
}

You can remove this code or overwrite the widget code in child theme, just copy the below code and put into your child theme functions.php file

add-action( 'widgets-init', 'wp-tuts-parent-unregister-widgets', 10 );

function yoga-parent-unregister-widgets() {

    unregister-widget( 'PWidgetName' );
    register-widget( 'MyCustomWidget' );
}

class MyCustomWidget extends WP-Widget {
    // Child Custom Widget code
}

Below code is the parent theme sidebar code.

class ParentWidgetName extends WP-Widget {
    // your widget code
}
function yoga-widgets-init()
{
    register-sidebar( array(
        'name' => _-( 'Main Sidebar', 'yoga' ),
        'id' => 'sidebar-1',
        'description' => _-( 'Widgets in this area will be shown on all posts and pages.' ),
        'before-widget' => '<div class="widget %2$s">',
        'after-widget'  => '</div>',
        'before-title'  => '<p>',
        'after-title'   => '</p>',
    ) );
}
/** Register sidebars by running pinboard-widgets-init() on the widgets-init hook. */
add-action( 'widgets-init', 'yoga-widgets-init' );

You can remove this code or overwrite the sidebar code in child theme, just copy the below code and put into your child theme functions.php file

add-action( 'widgets-init', 'wp-tuts-parent-unregister-sidebars', 10 );

function yoga-parent-unregister-sidebars() {

    unregister-sidebar( 'sidebar-1' );
}

Hope it helps you. Thank-you readers!
