The html_title_handler_field_node_title field handler re-renders title fields to enable allowed markup that would otherwise be transformed or stripped.

Class

html_title_handler_field_node_title

Override the standard node title rendering to enable select HTML tags.

Code

function render($values) {
  $output = parent::render($values);
  $elements = variable_get('html_title_allowed_elements', array(
    'em',
    'sub',
    'sup',
  ));
  if (count($elements)) {
    static $done = FALSE;

    // Ensure this block executes only once
    if (!$done) {

      // Add permitted elements to options so they are not stripped later
      $tags = array();
      foreach ($elements as $element) {
        $tags[] = '<' . $element . '>';
      }
      $this->options['alter']['preserve_tags'] .= ' ' . implode(' ', $tags);
      $done = TRUE;
    }

    // Decode permitted HTML elements
    $pattern = "/&lt;(\\/?)(" . implode('|', $elements) . ")&gt;/i";
    $output = preg_replace($pattern, '<$1$2>', $output);

    // Decode HTML character entities
    $pattern = "/&amp;([a-z0-9#]+);/";
    $output = preg_replace($pattern, '&$1;', $output);
  }
  return $output;
