示例1: insertBefore

* Inserts $newElement right before $reference.
*
* @param Zend_Form $form
* @param Zend_Form_Element $reference
* @param Zend_Form_Element $newElement
*/

if ($buttonIndex === 0) {
// Button is the first element, therefore no previous element
// whose order could be used for calculation exists.
// Choose a constant value which ensures that the calculated
// order value for the new element avoids re-ordering.

} else {

// starting with the captcha is required.
