怎么给dedecms的文章自动加上关键词的链接呢？

然后点击编辑查找如下代码：$query = "SELECT * FROM keywords WHERE rpurl<>'' ORDER BY rank DESC";
然后在这个代码的上面添加以下代码：

$dsql = new DedeSql(false);$query="select * from #@_keywords where rpurl<>'' ";$dsql->SetQuery($query);$dsql->Execute();while($row = $dsql->GetArray()){$key = trim($row['keyword']);$rul=trim($row['rpurl']);if($rul!="")if(!in_array($key, $kw))if(!in_array($kw,$key))if(substr_count($body,$key)<2){$karr[] = $key;$kaarr[] = "<a href='$rul'><u>$key</u></a>";}}
