Theme function for a CAPTCHA element.

File

./captcha.module, line 368

This module enables basic CAPTCHA functionality: administrators can add a CAPTCHA to desired forms that users without the 'skip CAPTCHA' permission (typically anonymous visitors) have to solve.

Code

function theme_captcha($variables) {
  $element = $variables['element'];
  if (empty($element['#description']) && !empty($element['#attributes']['title'])) {

    // Fix for Bootstrap-based themes.
    $element['#description'] = $element['#attributes']['title'];
  }
  if (!empty($element['#description']) && isset($element['captcha_widgets'])) {
    $fieldset = array(
      '#type' => 'fieldset',
      '#title' => t('CAPTCHA'),
      '#description' => $element['#description'],
      '#children' => drupal_render_children($element),
      '#attributes' => array(
        'class' => array(
          'captcha',
        ),
      ),
    );
    return theme('fieldset', array(
      'element' => $fieldset,
    ));
  }
  else {
    return '<div class="captcha">' . drupal_render_children($element) . '</div>';
  }
