Add multiple custom widget areas in WordPress

This code can used to add multiple widget areas in WordPress website. In this example I am going to add Header Ads, Footer Ads and Sidebar Ads widget areas.

Note – Please use unique id for each widget area and don’t forget to replace the textdomain with the active theme’s textdomain.

function add_multiple_widget_areas() {
	register_sidebar( array(
		'name'          => __( 'Header Ads', 'textdomain' ),
		'id'            => 'header-ads',
		'before_widget' => '<div id="%1$s" class="widget %2$s">',
		'after_widget'  => '</div>',
		'before_title'  => '<h3 class="widgettitle">',
		'after_title'   => '</h3>',
	));
	
	register_sidebar( array(
		'name'          => __( 'Sidebar Ads', 'textdomain' ),
		'id'            => 'sidebar-ads',
		'before_widget' => '<div id="%1$s" class="widget %2$s">',
		'after_widget'  => '</div>',
		'before_title'  => '<h3 class="widgettitle">',
		'after_title'   => '</h3>',
	));
	
	register_sidebar( array(
		'name'          => __( 'Footer Ads', 'textdomain' ),
		'id'            => 'footer-ads',
		'before_widget' => '<div id="%1$s" class="widget %2$s">',
		'after_widget'  => '</div>',
		'before_title'  => '<h3 class="widgettitle">',
		'after_title'   => '</h3>',
	));
}
add_action( 'widgets_init', 'add_multiple_widget_areas' );
