If I understand you correctly, you want to add custom error messages: http://framework.zend.com/manual/en/zend.form.elements.html#zend.form.elements.validators.errors
$name = new Zend_Form_Element_Text('name', array(
'label' => 'Név',
'maxlength' => 50,
'required' => true,
'validators' => array(
array('NotEmpty', true, array('messages' => array('isEmpty' =>
'Meg kell adnod a program nevét.'))),
),
));
