File

Tweaks signatures in ways inspired by other traditional forum software:

Code

function signature_forum_node_view($node, $view_mode, $langcode) {
  if (variable_get('user_signatures') && !empty($node->uid)) {

    // Fast return if the signature is disabled per post.
    if (isset($node->signature_forum_status) && !$node->signature_forum_status) {
      return $node;
    }

    // Add signature_forum to the render array.
    $user = user_load($node->uid);
    $node->content['signature_forum'] = array(
      '#signature' => check_markup($user->signature, $user->signature_format, '', TRUE),
      '#theme' => 'user_signature',
      '#pre_render' => array(
        'signature_forum_pre_render_user_signature',
      ),
      '#user' => $user,
    );
    $body = field_get_items('node', $node, 'body', $langcode);
    if ($body) {

      // Some body fields appear not to have a 'safe_value'.
      if (!empty($body[0]['safe_value'])) {
        $content = $body[0]['safe_value'];
      }
      else {
        $content = $body[0]['value'];
      }
      $node->content['signature_forum']['#content_length'] = drupal_strlen(strip_tags($content));
    }
    else {
      $node->content['signature_forum']['#content_length'] = 0;
    }
    $node->content['signature_forum']['#node'] = $node;
  }
  return $node;
}
