Question

I need to change the requirment of an input when a select change. I have this declaration on my form:

$name = $this->addElement('text', 'name', array(
                'required' => true,
                'label' => 'Name',
                'filters'    => array('StringTrim'),
            ));

I try with jquery in phtml file (view) :

$('#select').change(function(){
    $('#name').prop('disabled', true);
})

but not work, the input continue to be required. Anyone can heklp me?

You must remove required from the PHP side.

I can propose you this:

1. In your form, add an hidden element like this:

   $change_select = new Zend_Form_Element_Hidden('change_select');
    $this->addElement($change_select);
   

2. In your javascript :

   $('#select').change(function(){
       $("#change_select").val("change");
   })
   

3. In your controller, try something like this:

   // $form  is your form in your controller like : 
   // this $form = new Application_Form_Album();
   
   if ($this->getRequest()->isPost()) {
       $formData = $this->getRequest()->getPost();
       if ($formData['change_select'] == 'change'){
           $form->getElement('name')->setRequired(false);
       }
       if ($form->isValid($formData)) {
           ....
