Описание

It is not possible to check whether the $element
is already added to the form, therefore if you want to move the existing form
element to a new position, you'll have to use
removeElement():
<?php
$form->insertElementBefore($form->removeElement('foo', false), 'bar');
?>
Parameter
- object
&$element -
Element to insert (instance of HTML_QuickForm_element)
- string

Name of the element before which the new one is inserted
Return value
