Advanced info on free downloads in a gallery

This custom code tracks users who have downloaded a free image. It will show you a list of their email address and which images they downloaded. This relies on having the Digital Downloads and Analytics add-on enabled on your site.

add_action( 'sunshine_download_free_image', 'sunshine_customer_track_download_free_image_emails' );
function sunshine_customer_track_download_free_image_emails( $image ) {
	global $current_user;

	if ( is_user_logged_in() ) {
		$email = $current_user->user_email;
	} else {
		$email = SPC()->session->get( 'email' );
	}
	if ( $email ) {
		$events = $image->gallery->get_meta_value( 'free_download_events' );
		if ( empty( $entries ) ) {
			$events = array();
		}
		$events[] = array(
			'email'    => $email,
			'image_id' => $image->get_id(),
		);
		$image->gallery->update_meta_value( 'free_download_events', $events );
	}

}

add_action( 'sunshine_meta_gallery_analytics_display', 'sunshine_customer_track_download_free_image_emails_display', 99 );
function sunshine_customer_track_download_free_image_emails_display() {
	global $post;

	$gallery = sunshine_get_gallery( $post->ID );
	$events  = $gallery->get_meta_value( 'free_download_events' );
	if ( ! empty( $events ) ) {
		echo '<p><strong>' . __( 'Free Downloads', 'sunshine-photo-cart' ) . '</strong></p>';
		echo '<ul>';
		$downloads = array();
		foreach ( $events as $event ) {
			$image = sunshine_get_image( $event['image_id'] );
			if ( empty( $downloads[ $event['email'] ] ) ) {
				$downloads[ $event['email'] ] = array();

		}
		foreach ( $downloads as $email => $images ) {
