Make Addthis Button to check whether node is published

There will be more advanced admin settings in AddThis 3.0 and maybe this will be one of them. But for now you can check the node status in AddThis theme function.

Copy the function from module to you themes template.php and add an if to beginning. For example:

/**
 * Theme the AddThis button.
 */
function YOURTHEME_addthis_button($node, $teaser) {
  
  // Check that node is published.
  if($node->status == 0) {
    return;
  }
  
  global $_addthis_counter;

  // Fix IE's bug.
  if (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== FALSE) {
    drupal_add_link(array(
      'rel' => 'stylesheet',
      'type' => 'text/css',
      'href' => "http://s7.addthis.com/static/r07/widget02.css",
    ));
  }

  if (variable_get('addthis_dropdown_disabled', '0')) {
    $button = sprintf('
      <a class="addthis-button" href="http://www.addthis.com/bookmark.php"
        onclick="addthis_url   = location.href; addthis_title = document.title; return addthis_click(this);">
      <img src="%s" width="%d" height="%d" alt="%s" class="%s" /></a>',
      $_SERVER['HTTPS'] == 'on' ? addslashes(check_plain(variable_get('addthis_image_secure', 'https://secure.addthis.com/button1-share.gif'))) : addslashes(check_plain(variable_get('addthis_image', 'http://s9.addthis.com/button1-share.gif'))),
      variable_get('addthis_image_width', '125'),
      variable_get('addthis_image_height', '16'),
      trim(check_plain(strip_tags(variable_get('addthis_image_attributes_alt', 'share')))),
      trim(check_plain(strip_tags(variable_get('addthis_image_attributes_class', 'addthisimage'))))
    );
  }
  else {
    $button = sprintf('
      <a class="addthis-button" href="http://www.addthis.com/bookmark.php"
        onmouseover="return addthis_open(this, \'\', \'%s\', \'%s\')"
        onmouseout="addthis_close()"
        onclick="return addthis_sendto()"><img src="%s" width="%d" height="%d" alt="%s" class="%s" /></a>',
      $teaser ? url('node/'. $node->nid, array('absolute' => 1) ) : '[URL]',
      $teaser ? addslashes($node->title) : '[TITLE]',
      $_SERVER['HTTPS'] == 'on' ? addslashes(check_plain(variable_get('addthis_image_secure', 'https://secure.addthis.com/button1-share.gif'))) : addslashes(check_plain(variable_get('addthis_image', 'http://s9.addthis.com/button1-share.gif'))),
      variable_get('addthis_image_width', '125'),
      variable_get('addthis_image_height', '16'),
      trim(check_plain(strip_tags(variable_get('addthis_image_attributes_alt', 'share')))),
      trim(check_plain(strip_tags(variable_get('addthis_image_attributes_class', 'addthisimage'))))
    );
    if ($_addthis_counter == 1) {
      $button .= sprintf('<script type="text/javascript" src="%s/js/%d/addthis_widget.js">',
        $_SERVER['HTTPS'] == 'on' ? 'https://secure.addthis.com' : 'http://s7.addthis.com',
        variable_get('addthis_widget_version', '152')
      );
      $button .= '</script>';    
    }
  }
  return $button;
}

Would be nice to see this as an option (7.x)
