WP Discourse: advanced custom filter for discourse_publish_format_html

For others, here’s how you’d modify my original block of code to work with the updated plugin, but this time with the desired oneboxed default :slight_smile::

// when publishing a post to Discourse
function cosmos_custom_publish_format_html( $output, $post_id ) {
	$post = get_post( $post_id );
	
	// if featured image is present, use it
	if ( has_post_thumbnail( $post_id ) ) {
		$image = "{thumbnail}<br><br>";
	} else {
		$image = "";
	}

    // if post is an event, get the custom field information
    if ( 'event' === $post->post_type) {
    	$startdate = get_post_meta($post->ID, '_event_start_date', true);
    	$starttime = get_post_meta($post->ID, '_event_start_time', true);
    	$enddate = get_post_meta($post->ID, '_event_end_date', true);
    	$endtime = get_post_meta($post->ID, '_event_end_time', true);
        $startdateformatted = date('j M Y', strtotime($startdate));
        $starttimeformatted = date('g:i a', strtotime($starttime));
        $enddateformatted = date('j M Y', strtotime($enddate));
        $endtimeformatted = date('g:i a', strtotime($endtime));
        $eventallday = get_post_meta($post->ID, '_event_all_day', true);
        $eventtimezone = get_post_meta($post->ID, '_event_timezone', true);
        $videoconferenceurl = get_post_meta($post->ID, 'Video Conference URL', true);
        
        if ($startdate == $enddate && $eventallday !== '1') {
          $eventinfo = "<strong>Date/Time:</strong> {$startdateformatted} @ {$starttimeformatted} - {$endtimeformatted} {$eventtimezone}";
        }
        
        if ($startdate !== $enddate && $eventallday !== '1') {
          $eventinfo = "<strong>Date/Time:</strong> {$startdateformatted} @ {$starttimeformatted} - {$enddateformatted} {$endtimeformatted} {$eventtimezone}";
        }
        
        if ($startdate == $enddate && $eventallday == '1') {
          $eventinfo = "<strong>Date/Time:</strong> {$startdateformatted} <i>All Day</i>";
        }
        
        if ($startdate !== $enddate && $eventallday == '1') {
          $eventinfo = "<strong>Date/Time:</strong> {$startdateformatted} - {$enddateformatted}";
        }
        
        if ($videoconferenceurl !== '') {
          $videoconferenceurlformatted = "<strong>Video Conference Link:</strong> {$videoconferenceurl}<br><br>";
        }
        
        if ($videoconferenceurl == '') {
          $videoconferenceurlformatted = "";
        }
                
        ob_start();
