Yoast SEO: Changing the Enhanced Slack sharing output

As of Yoast SEO 15.2 we've added the option to enhance the way URLs are displayed when they're shared on Slack. For more info on that feature, please see the help page: enhanced Slack sharing.

The data shown is a set of two labels with attached data, which will be output as string. You can filter this data by simply filtering the array through the wpseo_enhanced_slack_data filter.

For example:

class Yoast_SEO_Enhance_Slack_Data {

	/**
	 * Class constructor
	 */
	public function __construct() {
		add_filter( 'wpseo_enhanced_slack_data', [ $this, 'generate_slack_data' ], 10, 2 );
	}

	/**
	 * Change Enhanced Slack sharing data labels.
	 *
	 * @param array                  $data         The Slack labels + data.
	 * @param Indexable_Presentation $presentation The indexable presentation object.
	 *
	 * @return array The Slack labels + data.
	 */
	public function generate_slack_data( array $data, Indexable_Presentation $presentation ) {
		if ( is_singular( 'jobs' ) ) {
			$hours    = get_post_meta( $presentation->model->object_id, 'jobs_hours', true );
			$location = get_post_meta( $presentation->model->object_id, 'jobs_location', true );
			$data = [
				'Location' => $location,
				'Hours'    => $hours,
			];
		}

		return $data;
	}
