A Drupal form checkboxes example (HTML check boxes)

Drupal form FAQ: How do I create an HTML checkbox in a Drupal form?

Assuming that you're comfortable with creating a Drupal form, you can create a Drupal form checkbox (technically a Drupal checkboxes element) as easily as this:

# an html checkbox for our drupal form

# the options to display in our checkboxes
$toppings = array(
  'pepperoni' => t('Pepperoni'),
  'black_olives' => t('Black olives'), 
  'veggies' => t('Veggies')
);

# the drupal checkboxes form field definition
$form['pizza'] = array(
  '#title' => t('Pizza Toppings'),
  '#type' => 'checkboxes',
  '#description' => t('Select the pizza toppings you would like.'),
  '#options' => $toppings,
);

The checkbox is specified in this line of code:

  '#type' => 'checkboxes',

Note: I originally wrote this tutorial for Drupal 6, and I just confirmed that it works for Drupal 7 as well.

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

You can add even more fields to your Drupal checkbox definition. The fields you can add are defined in the grid at this Drupal Form API reference page.
