Restrict results from the current author archive page

Custom code to display only results from the current author - when on the author archive page

What is this, and where do I put this custom code?

add_action('asp_layout_in_form', 'asp_layout_in_form_author_archive_input', 10);
function asp_layout_in_form_author_archive_input() {
	if ( is_author() ) {
		?>
		<input type="hidden" styl="display:none;" name="asp_author_archive" value="<?php echo get_queried_object_id(); ?>">
		<?php
	}
}


add_filter( 'asp_query_args', 'asp_archive_page_category_restriction', 10, 3 );
function asp_archive_page_category_restriction($args, $search_id, $options) {
	if ( isset($options['asp_author_archive']) ) {
		if ( !isset($args['post_user_filter']['include']) ) {
			$args['post_user_filter']['include'] = array();
		}
		$args['post_user_filter']['include'] = array_unique(array_merge(
			$args['post_user_filter']['include'],
			array($options['asp_author_archive'])
		));
	}
	return $args;
}
