I know this is a customization outside your support area. But I’m done to 95%.
All that is left is to save the custom taxonomy value from the frontend.
add_action(‘tribe_events_update_meta’, ‘add_tax_value’,10,1);
function add_tax_value($event_id){
global $post;
print_r($_POST);
//wp_set_object_terms( $event_id, $_POST[“tax-value”], ‘kommun’);
}
All values in $_POST is printed, but my tax-value seems to be filtered.
This is beyond my current expertise and as you mention beyond the scope of the forums.
