织梦当前文档内容自动关联tag标签做内链

实现教程

1、后台-系统-核心设置-关键字替换，选择【是】

2、后台-系统-其他选项-关键词替换次数，填【1】或者【0】

1：表示文档内容里有多个关键词，只让1个是内链

0：表示文档内容里有多个关键词，都是内链

根据自己的需要填

3、打开 /include/arc.archives.class.php 找到，大概在1187行至1241行，整个函数

function ReplaceKeyword($kw,&$body){...中间代码省略}

整个改成

function ReplaceKeyword($kw,&$body){global $cfg_replace_num;//如果当前文档没有tag直接不内链，需要匹配所有tag的话，删除下面行if(GetTags($this->Fields['aid']) == '') return $body;$search = "/(alts*=s*|titles*=s*|srcs*=s*)["|'](.+?)["|']/is";$body = preg_replace_callback($search, array('Archives', '_base64_encode'), $body);$addsql = '';$this->dsql->SetQuery("SELECT tid FROM `58pic_taglist` WHERE aid = '{$this->Fields['aid']}' ");$this->dsql->Execute();$ids = '';while($row = $this->dsql->GetArray()){$ids .= ( $ids=='' ? $row['tid'] : ','.$row['tid'] );}if($ids != ''){$addsql = " WHERE id IN($ids) ";}$query = "SELECT * FROM `58pic_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'] = $cfg_cmsurl."/tags.php?/".urlencode($row['tag'])."/";$linkdatas[] = $row;}if($linkdatas) {$word = $replacement = array();foreach($linkdatas as $v) {$word0[] = "/<a[^>]*>{$v['keyword']}</a>/is";$word1[] = '/'.$v['keyword'].'/is';$word2[] = $v['keyword'];$replacement[] = '<a href="'.$v['rpurl'].'" target="_blank">'.$v['keyword'].'</a>';}if($cfg_replace_num) {$body = preg_replace($word0, $word2, $body, $cfg_replace_num);$body = preg_replace($word1, $replacement, $body, $cfg_replace_num);} else {$body = str_replace($word2, $replacement, $body);}}$body = preg_replace_callback($search, array('Archives', '_base64_decode'), $body);return $body;}function _base64_encode($matches) {return $matches[1].""".base64_encode($matches[2]).""";}function _base64_decode($matches) {return $matches[1].""".base64_decode($matches[2]).""";} 

如图

如果你的tag链接是伪静态或者静态链接，把里面的

$cfg_cmsurl."/tags.php?/".urlencode($row['tag'])."/";

改成与include/taglib/tag.lib.php里面的一致即可

4、完成，动态的直接看效果，静态的记得重新生成文档看效果
