Radio

Zend\Form\Element\Radio is meant to be paired with the Zend\Form\View\Helper\FormRadio for HTML inputs with type radio. This element adds an InArray validator to its input filter specification in order to validate on the server if the value is contains within the radio value elements.

Basic Usage

This element automatically adds a "type" attribute of value "radio" for every radio.

    use Zend\Form\Element;
    use Zend\Form\Form;

    $radio = new Element\Radio('gender');
    $radio->setLabel('What is your gender ?');
    $radio->setValueOptions(array(
        '0' => 'Female',
        '1' => 'Male',
    ));

    $form = new Form('my-form');
    $form->add($radio);

Using the array notation:

 use Zend\Form\Form;

    $form = new Form('my-form');
    $form->add(array(
        'type' => 'Zend\Form\Element\Radio',
        'name' => 'gender',
        'options' => array(
            'label' => 'What is your gender ?',
            'value_options' => array(
                '0' => 'Female',
                '1' => 'Male',
            ),
        ),
    ));
