dedecms织梦文档内容自动关联tag标签加入内链的方法
最终实现效果如下图：内容生成之后会自动加上本篇文章的tags标签（文档生成时候自动加入，编辑器中内容实际没加入，更有利）
function ReplaceKeyword($kw,&$body) { ...中间代码省略 } 整个改成
function ReplaceKeyword($kw,&$body){global $cfg_replace_num;$search = "/(alts*=s*|titles*=s*|srcs*=s*)["|'](.+?)["|']/is";$body = preg_replace_callback($search, array('Archives', '_base64_encode'), $body);$addsql = '';if(isset($this->Fields['tags']) && !empty($this->Fields['aid'])){$this->dsql->SetQuery("SELECT tid FROM `dede_taglist` WHERE aid = '{$this->Fields['aid']}' ");$this->dsql->Execute();$ids = '';while($row = $this->dsql->GetArray()){$ids .= ( $ids=='' ? $row['tid'] : ','.$row['tid'] );}if($ids != ''){$addsql = " WHERE id IN($ids) ";}if($addsql=='') return $body;}$query = "SELECT * FROM `dede_tagindex` $addsql ORDER BY addtime DESC";$this->dsql->SetQuery($query);$this->dsql->Execute();$linkdatas = array();while($row = $this->dsql->GetArray()){$row['keyword'] = $row['tag'];$row['rpurl'] = $cfg_cmsurl."/".urlencode($row['tag'])."/";$linkdatas[] = $row;}if($linkdatas) {$word = $replacement = array();foreach($linkdatas as $v) {$word1[] = '/(?!(<a.*?))' . preg_quote($v['keyword'], '/') .
