dedecms关键字不需要在keyword中设置实现內链

dedecms关键词內连维护默认是需要和发布文章时匹配通过keyword中设置的关键字作为条件替换来完成的，今天分享的是不通过keyword中设置的关键字作为条件替换，而是在数据库中所有的词中索引匹配的织梦仿站方法： 测试环境为：DEDECMS v5.7 第一步：/include/arc.archives.class.php（DEDE v5.7） if($arr['type']=='htmltext' && $GLOBALS['cfg_keyword_replace']=='Y' && !empty($this->Fields['keywords'])) 改为：if($arr['type']=='htmltext' && $GLOBALS['cfg_keyword_replace']=='Y')     第二步：/include/arc.archives.class.php（DEDE v5.7）中的 ReplaceKeyword 方法改成：     function ReplaceKeyword($kw,&$body) { global $cfg_cmspath; $maxkey = 3; $kws = explode(",",trim($kw)); //以分好为间隔符 $i=0; $karr = $kaarr = $GLOBALS['replaced'] = array();   //暂时屏蔽超链接 $body = preg_replace("#(<a(.*))(>)(.*)(<)(\/a>)#isU", '\\1-]-\\4-[-\\6', $body);   /* foreach($kws as $k) { $k = trim($k); if($k!="") { if($i > $maxkey) { break; } $myrow = $this->dsql->GetOne("SELECT * FROM cn_keywords WHERE keyword='$k' AND rpurl<>'' "); if(is_array($myrow)) { $karr[] = $k; $GLOBALS['replaced'][$k] = 0; $kaarr[] = "<a href='{$myrow['rpurl']}'><u>$k</u></a>"; } $i++; } } */ $query = "SELECT * FROM cn_keywords WHERE rpurl<>'' ORDER BY rank DESC"; $this->dsql->SetQuery($query); $this->dsql->Execute(); $j = 0; while($row = $this->dsql->GetArray()) { $action = 1; if($j >= $maxkey) break; $key = trim($row['keyword']);
