Zend Form Disable Fields

I use this little function as part of my base form class to enable me to easily lock certain form elements.

PLAIN TEXT
PHP:
  1. public function lockField($field){       
  2.         $elem = $this->getElement($field);       
  3.         $elem->setAttrib('disabled', true);
  4.         $elem->setAttrib('readonly',true);
  5.     }

usage might be like the following:

PLAIN TEXT
PHP:
  1. public function makeForm($action){
  2.     $form = new My_Form(array('action'=>$action));
  3.     $form->addElement(.. custom form add element function);
  4.     $form->lockField('fieldname');
  5.     $form->addSubmit(.. custom add submit function);
  6.     return $form;
  7. }

How could you attach this functionality to a check box? Eg. You have a form with check boxes. When you click a check box you want it to display a text box element.

An example is where you are trying to find out how a customer came to your page.
They click the 'other - please specify' check box and the text box appears so they can enter text.

I think you would be best approaching that with javascript.

you could use this function to lock the textbox and then use javascript to unlock and hide it.
