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

# 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',
