Show custom post types in dashboard activity widget

Here’s how I got to show custom post types in the dashboard activity widget.

• Copied & pasted the function wp_dashboard_recent_posts (from wp-admin/includes/dashboard.php)
• Changed it slightly to pass post_type in the argument
• Replaced the activity widget with one that calls the new function

The following can be put in functions.php or a plugin.

/**
 *
 * Show custom post types in dashboard activity widget
 *
 */

// unregister the default activity widget
add_action('wp_dashboard_setup', 'remove_dashboard_widgets' );
function remove_dashboard_widgets() {

    global $wp_meta_boxes;
    unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_activity']);

}

// register your custom activity widget
add_action('wp_dashboard_setup', 'add_custom_dashboard_activity' );
function add_custom_dashboard_activity() {
    wp_add_dashboard_widget('custom_dashboard_activity', 'Activities', 'custom_wp_dashboard_site_activity');
}

// the new function based on wp_dashboard_recent_posts (in wp-admin/includes/dashboard.php)
function wp_dashboard_recent_post_types( $args ) {

/* Chenged from here */

	if ( ! $args['post_type'] ) {
		$args['post_type'] = 'any';
	}

	$query_args = array(
		'post_type'      => $args['post_type'],

/* to here */

		'post_status'    => $args['status'],
		'orderby'        => 'date',
		'order'          => $args['order'],
		'posts_per_page' => intval( $args['max'] ),
		'no_found_rows'  => true,
		'cache_results'  => false
	);
	$posts = new WP_Query( $query_args );

	if ( $posts->have_posts() ) {

		echo '<div id="' . $args['id'] . '" class="activity-block">';

		if ( $posts->post_count > $args['display'] ) {
			echo '<small class="show-more hide-if-no-js"><a href="#">' . sprintf( __( 'See %s more…'), $posts->post_count - intval( $args['display'] ) ) . '</a></small>';
		}

		echo '<h4>' . $args['title'] . '</h4>';

		echo '<ul>';

		$i = 0;
		$today    = date( 'Y-m-d', current_time( 'timestamp' ) );
		$tomorrow = date( 'Y-m-d', strtotime( '+1 day', current_time( 'timestamp' ) ) );

		while ( $posts->have_posts() ) {
			$posts->the_post();

			$time = get_the_time( 'U' );
			if ( date( 'Y-m-d', $time ) == $today ) {
				$relative = __( 'Today' );
			} elseif ( date( 'Y-m-d', $time ) == $tomorrow ) {
				$relative = __( 'Tomorrow' );
			} else {
				/* translators: date and time format for recent posts on the dashboard, see https://php.net/date */
				$relative = date_i18n( __( 'M jS' ), $time );
			}

 			$text = sprintf(
				/* translators: 1: relative date, 2: time, 4: post title */
 				__( '<span>%1$s, %2$s</span> <a href="%3$s">%4$s</a>' ),
  				$relative,
  				get_the_time(),
  				get_edit_post_link(),
  				_draft_or_post_title()
  			);

 			$hidden = $i >= $args['display'] ? ' class="hidden"' : '';
 			echo "<li{$hidden}>$text</li>";
			$i++;
		}

		echo '</ul>';
		echo '</div>';

	} else {
		return false;
	}

	wp_reset_postdata();

	return true;
}

// The replacement widget
function custom_wp_dashboard_site_activity() {

    echo '<div id="activity-widget">';

    $future_posts = wp_dashboard_recent_post_types( array(
