FAQ Field Provides a field for frequently asked questions.

Code

function faqfield_field_presave($entity_type, $entity, $field, $instance, $langcode, &$items) {
  foreach ($items as $key => &$values) {
    if (is_array($values['answer'])) {

      // Normal textarea's and textfields put their values simply in by
      // array($name => $value); Unfortunately text_format textareas put
      // them into an array so also the format gets saved: array($name
      // => array('value' => $value, 'format' => $format)).
      // So the API will try to save normal textfields to the 'name' field
      // and text_format fields to 'answer_value' and 'answer_format'.
      // To bypass this, we pull the values out of this array and force
      // them to be saved in 'answer' and 'answer_format'.
      $values['answer_format'] = $values['answer']['format'];
      $values['answer'] = $values['answer']['value'];
    }

    // Here we test if the values are default ones, yes? -> remove them.
    if (isset($instance['default_values'])) {
      if ($values['question'] == $instance['default_values']['question']) {
        if ($values['answer'] == $instance['default_values']['answer']) {
          unset($items[$key]);
        }
      }
    }
