Widgets – ACF adding -2 to the end of widget ID

I’m instantiating a widget using the Widget API code directly from codex, my constructor looks like this:

		function __construct() {
			parent::__construct(
				'some_widget',
				esc_html__( 'Some Widget', 'text-domain' ),
				array( 'description' => esc_html__( 'A Widget', 'text-domain' ) )
			);
		}

Yet if I check for rows like this:

if ( have_rows( 'featured_pages_widget', 'widget_some_widget' ) ) :

I get nothing. But if I add -2

if ( have_rows( 'featured_pages_widget', 'widget_some_widget-2' ) ) :

It works fine. Any ideas?

I ended up figuring this out on my own, and without a filter as described in the docs. In my case, I was using the widget API ‘foo’ example from codex. if you are following along and have similar issues use:

$args[‘widget_id’]

As the widget id. It wants the id of the instance, not just the widget itself. A fuller example using a repeater:

		public function widget( $args, $instance ) {
			echo $args['before_widget'];
			if ( ! empty( $instance['title'] ) ) {
				echo $args['before_title'] . apply_filters( 'widget_title', $instance['title'] ) . $args['after_title'];
			}
			if ( have_rows( 'some_fields', 'widget_' . $args['widget_id'] ) ) {
	while ( have_rows( 'some_fields', 'widget_' . $args['widget_id'] ) ) {
         the_row();
         // do stuff in here
        }

}
			echo $args['after_widget'];
		}
