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方法：测试环境为：DEDECMS v5.7第一步：/include/arc.archives.class.php（DEDE v5.7） line 231：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’]);
