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():
$form->insertElementBefore($form->removeElement('foo', false), 'bar'); |
Element to insert (instance of HTML_QuickForm_element)
Name of the element before which the new one is inserted
