A module that adds one of the ShareThis widget to your website.

Code

  // Don't display if searched
  if ($view_mode == 'search_result' || $view_mode == 'search_index') {
    return;
  }

  // First get all of the options for the sharethis widget from the database:
  $data_options = get_options_array();

  // This looks to see if the path variable has been posted by some rewrite module.
  // This is not super efficient, O(N), but N is often less than 20.
  $is_path = FALSE;

    if ($data_options['viewMode'] == "1" && $view_mode == "teaser") {

      // Do nothing.
    }
    else {

      // This puts the buttons on the node and adds the necessary scripts.
      // You can change the weight to change whether the buttons are near the top or bottom of the node.
      // Default is at the bottom:
      $node->content['my_additional_field'] = array(
        '#markup' => get_button_HTML($data_options, $mPath, $mTitle),
        '#weight' => 10,
