Radio

Zend\Form\Element\Radio is meant to be paired with the FormRadio helper 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('likes_chocolate');
$radio->setLabel('Do you like chocolate?');
$radio->setValueOptions([
    '0' => 'No',
    '1' => 'Yes',
]);

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

Using array notation:

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

$form = new Form('my-form');
$form->add([
    'type' => Element\Radio::class,
    'name' => 'likes_chocolate',
    'options' => [
        'label' => 'Do you like chocolate?',
        'value_options' => [
            '0' => 'No',
            '1' => 'Yes',
        ],
    ],
]);
