WP_Sitemaps_Provider{} WP 5.5.0

Провайдер создается путем создания своего класса на основе этого и дальнейшей его регистрацией с помощью функции wp_register_sitemap_provider().

add_filter( 'init', 'wpkama_register_sitemap_providers' );
function wpkama_register_sitemap_providers(){

	require_once __DIR__ .'/class-My_Sitemaps_Provider.php';

	$provider = new Coredata_Sitemaps_Provider();

	wp_register_sitemap_provider( 'provider_name', $provider );
}

Использование

class My_Sitemaps_Provider extends WP_Sitemaps_Provider {

	public function __construct() {
		$this->name        = 'name'; 
		$this->object_type = 'type';
	}

	/**
	 * Gets a URL list for a sitemap.
	 *
	 * @param int    $page_num       Page of results.
	 * @param string $object_subtype Optional. Object subtype name. Default empty.
	 *
	 * @return array Array of URLs for a sitemap.
	 */
	public function get_url_list( $page_num, $object_subtype = '' ) {

		// code here

		return $url_list;
	}

	/**
	 * Gets the max number of pages available for the object type.
	 *
	 * @param string $object_subtype Optional. Object subtype. Default empty.
	 * @return int Total number of pages.
	 */
	public function get_max_num_pages( $object_subtype = '' ) {

		$total = 99999;

		return (int) ceil( $total / wp_sitemaps_get_max_urls( $this->object_type ) );
	}
}
