How do I set the default value for a Zend_Form radio element?


I have a radio element with two options. I want to set one as the default value in case the user forgets to check it. How can I do this?


$this->addElement('radio', 'choose', array(
    'required'   => true,
    'multiOptions' => array(
        'yes' => 'heck yes',
        'no' => 'please no'
    'value' => 'yes' //key of multiOption

use setValue with key. For example:

$enablestate=new Zend_Form_Element_Radio('enablestate');
