  • I was actually able to take care of it with the following code (which is similar to your own…just left open ended for other uses than my stated one) so I could just easily display the page’s last update time stamp. Whenever the client fills in and submits the form on the front it to update the custom fields the form is tied to, it updates the page’s time stamp. Can be used for any acf_form() used actually. For some reason acf_form doesn’t do this on its own. Personally, I think it should considering its intended purpose.

    // Updates FYI last update timestamp when custom field is updated
    function my_acf_save_post( $post_id ) {
      // bail out early if we don't need to update the date
      if( is_admin() || $post_id == 'new' ) {
       global $wpdb;
       $datetime = date("F j, Y g:i a");
       $query = "UPDATE $wpdb->posts
                  post_modified = '$datetime'
                  ID = '$post_id'";
        $wpdb->query( $query );
    // run after ACF saves the $_POST['acf'] data
    add_action('acf/save_post', 'my_acf_save_post', 20);
