Alter all webform fields

Question

If we want to alter webform item e.g. add a colon : to a label of a specific field, we use this:

$form['submitted']['my_form_component']['#title'] = $form['submitted']['my_form_component']['#title'] . ":";

But what if we want to apply that colon to all field labels and not just that one my_form_component?

Current code:

function MYTHEME_form_alter( &$form, &$form_state, $form_id ){
  if (strpos($form_id, 'webform_client_form_') === 0) {
    $form['submitted']['my_form_component']['#title'] = $form['submitted']['my_form_component']['#title'] . ":";
  }
}

Answer 1

You should be able to do it with a recursive function, looping through the render array and adding a colon to any elements that have a #title element.

function addColonsToTitles(&$element) {
  if (isset($element['#title'])) {
    $element['#title'] .= ':';
  }

  foreach (element_children($element) as $index) {
    addColonsToTitles($element[$index]);
  }
}

function MYTHEME_form_alter( &$form, &$form_state, $form_id ){
  if (strpos($form_id, 'webform_client_form_') === 0) {
    addColonsToTitles($form['submitted']);
  }
}
