object &HTML_QuickForm::insertElementBefore ( 
      object &$element
       , string $nameAfter
     )
Inserts a new element right before the other element.
       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');
?>
&$elementElement to insert (instance of HTML_QuickForm_element)
$nameAfterName of the element before which the new one is inserted
return reference to inserted element.

|---|---|---|---|
| QUICKFORM_INVALID_ELEMENT_NAME | Several elements named $nameAfter exist in HTML_QuickForm::insertElementBefore() | 
         Several elements named $nameAfter (e.g.: radios) exist in the form. The method does not handle this case. | 
         Insert before some other element. Consider adding a dummy element with a unique name. | 
| QUICKFORM_INVALID_ELEMENT_NAME | Element '$elementName' already exists in HTML_QuickForm::insertElementBefore() | Element exists with the same name as $element but of different type | 
         Give some other name to the inserted element. | 
| QUICKFORM_NONEXIST_ELEMENT | Element $nameAfter does not exist in HTML_QuickForm::insertElementBefore() | 
         Tried to insert before a non-existant element | Check the element's name spelling |
