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']);
