  -> condition('t.entity_id', $nid);
$t = $query->execute()->fetchAll();
$tids = '';
$d = '';
foreach ($t as $ob)
{ 
$tids .= $d . $ob -> field_tags_tid;
$d = ',';
} 
$tids = explode(",", $tids); 
 
$query = db_select('taxonomy_term_data','t')
      -> fields('t', array('tid','name'))
          -> condition('t.tid', $tids, 'IN')
  -> condition('t.vid', 1);
$t = $query->execute()->fetchAll();
$tags = '';
foreach ($t as $ob)
{ 
   //$name = trim($ob -> name);//去掉头尾空格
   //$name = preg_replace('/\s(?=\s)/', '', $name);//去掉重复空格
   //$name = preg_replace('/[\n\r\t]/', ' ', $name);//将非空格变成空格
   //$name = str_replace(' ', '-', $name);
$name = $ob -> name;
$tags .= l($ob -> name, 't/'.$name, array('attributes' => array('class' => 'post-tag')));
} 
return $tags; 
}
