The problem will be somewhere else, it doesn't matter if hidden is after the button.

@dg

in post.php ，how get posted hidden field 'id' value by $form ?

   if ($form->isSubmitted() && $form->isValid()) {
        $values = $form->getValues();

       print_r($values);exit;
   }

Array ( [name] =>test [content_html] => xxx
$values has no 'id' field value
