How to show a empty field

Posted by hkvega01 on March 9, 2013 at 12:51pm

i've created a custom field for a content type, which not yet provided with a form let users input value while adding content. i'm just want the field show my wanted value, the following is the testing code

function codeless_discounts_field_field_formatter_view($entity_type, $entity, $field, $instance, $langcode, $items, $display) {
  $element = array();

  switch ($display['type']) {
    // This formatter simply outputs the field as text and with a color.
    case 'default':
     if (empty($items)) {
        $item = array();
        $item["codeless_discounts"] = 'test';
        $items[] = $item;
      }
      foreach ($items as $delta => $item) {
        $element['discount'] = array(
          '#type' => 'html_tag',
          '#tag' => 'p',
          '#attributes' => array(
            //'style' => 'color: ' . $item['codeless_discounts'],
          ),
          '#value' => t('The color code in this field is @code', array('@code' => $item["codeless_discounts"])),
        );
      }
      break;
  }

  return $element;
}

i discovered that, if the field is empty of the content, the field don't displays, even i hardcode the #value, anyway i can solve the problem?

You might want to look at the field example in the developers example module.
