Hello,
The tooltip uses the excerpt, but not the_excerpt.
The function:
tribe_events_template_data()
Is what grabs the data for the tooltip and encodes it.
That function uses this for the excerpt:
if ( has_excerpt( $event->ID ) ) {
$excerpt = $event->post_excerpt;
} else {
$excerpt = $event->post_content;
}
Found around line 1161 of this file:
the-events-calendar\public\template-tags\general.php
You can get some insight on how the tooltip is created by seeing these two pages:
the-events-calendar\views\month\single-event.php
the-events-calendar\views\month\tooltip.php
Let me know if you have any follow up questions.
Thanks
