织梦cms内容页如何调用当前页面url地址

if(!function_exists('GetArcUrl'))
{
    function GetArcUrl($id)
   {
      global $dsql;
      $arcRow = $dsql->GetOne("SELECt * FROM dede_archives WHERe `id` = '{$id}'");
      $typeRow = $dsql->GetOne("SELECt * FROM dede_arctype WHERe `id` = '{$arcRow['typeid']}'");
      $arcurl = GetFileUrl($id,$arcRow['typeid'],$arcRow['senddate'],$arcRow['title'],$arcRow['ismake'],
      $arcRow['arcrank'],$typeRow['namerule'],$typeRow['typedir']
     ,$arcRow['money'],$arcRow['filename'],$typeRow['moresite'],$typeRow['siteurl'],
      $typeRow['sitepath']);
      return $arcurl;
  }
}

然后在内容页通过{dede:field.id function="GetArcUrl(@me)"/}进行调用
