A Drupal form radio buttons example (Drupal radios field)

Drupal radio buttons FAQ: How do I create an HTML radio button widget in a Drupal form?

Assuming that you're already comfortable with creating a Drupal form, you can create Drupal form radio buttons (technically a Drupal "radios" element) like this:

# an html radio button widget for a drupal form

# the options to display in our form radio buttons
$options = array(
  'punt' => t('Punt'),
  'field_goal' => t('Kick field goal'), 
  'run' => t('Run'),
  'pass' => t('Pass'),
);

$form['fourth_down'] = array(
  '#type' => 'radios',
  '#title' => t('What to do on fourth down'),
  '#options' => $options,
  '#description' => t('What would you like to do on fourth down?'),
  '#default_value' => $options['punt'],
);

This Drupal form element is declared to be a collection of radio buttons in this Drupal form type declaration:

  '#type' => 'radios',

This Drupal radio buttons form field ("radios") )definition renders an HTML radio buttons field that looks like this:

(If you're not comfortable with creating a Drupal module or Drupal form, please see my first Drupal form example/tutorial.)

Note: I initially wrote this tutorial for Drupal 6, and I just tested it with Drupal 7, and it works there as well.
