Hey Adam
Turns out they have two actions after a submissions is published 🙂
So you need to add to your functions.php (the second two actions might not be necessary but first two for sure):
add_action('fes_submission_form_edit_published', 'sf_edd_fes_submission_form_published', 20, 1);
add_action('fes_submission_form_new_published', 'sf_edd_fes_submission_form_published', 20, 1);
add_action('fes_submission_form_edit_pending', 'sf_edd_fes_submission_form_published', 20, 1); // this might not be necessary
add_action('fes_submission_form_new_pending', 'sf_edd_fes_submission_form_published', 20, 1); // this might not be necessary
function sf_edd_fes_submission_form_published($post_id)
{
do_action('search_filter_update_post_cache', $post_id);
}
🙂
