This is an example demonstrating how a module can define custom form and render elements.

Code

function form_example_phonenumber_discrete_process($element, &$form_state, $complete_form) {
  // #tree = TRUE means that the values in $form_state['values'] will be stored
  // hierarchically. In this case, the parts of the element will appear in
  // $form_state['values'] as
  // $form_state['values']['<element_name>']['areacode'],
  // $form_state['values']['<element_name>']['prefix'],
  // etc. This technique is preferred when an element has member form
  // elements.
  $element['#tree'] = TRUE;

  // Normal FAPI field definitions, except that #value is defined.
  $element['areacode'] = array(
    '#type' => 'textfield',
    '#size' => 3,
    '#maxlength' => 3,
    '#value' => $element['#value']['areacode'],
    '#required' => TRUE,
    '#prefix' => '(',
    '#suffix' => ')',
  );
  $element['prefix'] = array(
    '#type' => 'textfield',
    '#size' => 3,
    '#maxlength' => 3,
    '#required' => TRUE,
    '#value' => $element['#value']['prefix'],
  );
  $element['extension'] = array(
    '#type' => 'textfield',
    '#size' => 4,
    '#maxlength' => 4,
    '#value' => $element['#value']['extension'],
  );

  return $element;
}
