Thanks so much!! I ended up figuring it out with this (below), but your way is probably much better…
function tribe_add_thumbnail_to_single_next( $link ) {
global $post;
$next = Tribe__Events__Main::instance()->get_closest_event( $post, ‘ next’ );
if ( ! is_a( $next, ‘WP_Post’ ) || ! isset( $next->ID ) ) {
return $link;
}
return tribe_get_next_event_link(‘
ID, thumbnail, false, false ) . ‘” />
Next Event:
‘ . get_the_title( $next->ID ) . ‘
‘);// . $link;
}
add_filter( ‘tribe_the_next_event_link’, ‘tribe_add_thumbnail_to_single_next’ );
