织梦后台的关键词维护默认的情况是字数少的词优先于字数多的词，比如我们有两个这样的词：创业、创业方向，第二个词包含了第一个词，在文章中如果出现“创业方向”这个词，默认情况下只会给创业两个字添加关键词超链接，而不是整个词，那么我们怎么样才能实现字数多的词优先于字数少的词呢？织梦97告诉大家具体的解决方法：
 
我们找到并打开/include/arc.archives.class.php文件，在里面找到如下代码：
function ReplaceKeyword($kw,&$body)     {         global $cfg_cmspath;         $maxkey = 5;         $kws = explode(",",trim($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 = $this->dsql->GetOne("SELECT * FROM dede_keywords WHERE keyword='$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 dede_keywords WHERE rpurl<>'' ORDER BY rank DESC";         $this->dsql->SetQuery($query);         $this->dsql->Execute();         while($row = $this->dsql->GetArray())         {             $key = trim($row['keyword']);             $key_url=trim($row['rpurl']);             $karr[] = $key;             $kaarr[] = "<a href='$key_url' target='_blank'><u>$key</u></a>";         }         // 这里可能会有错误 织梦58http://www.dede58.com         $body = @preg_replace("#(^|>)([^<]+)(?=<|$)#sUe", "_highlight('2', $karr, $kaarr, '1')", $body);         //恢复超链接         $body = preg_replace("#(<a(.*))-]-(.*)-[-(/a>)#isU", '1>3<4', $body);         return $body;     }
 
找到后将其替换为如下代码：
 
    function ReplaceKeyword($kw,&$body)     {     global $cfg_cmspath,$dsql;     $maxkey = 5;     $kws = explode(",",trim($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);     $query="SELECT * FROM dede_keywords WHERE rpurl<>'' and sta=1 ORDER BY length(keyword)desc";     $dsql->SetQuery($query);     $dsql->Execute();     while($row = $dsql->GetArray())     {     $key = trim($row['keyword']);     $key_url=trim($row['rpurl']);     $karr[] = $key;     $kaarr[] = "<u><a href='$key_url' target='_blank'>$key</a></u>";     }     foreach ($karr as $key => $word)     {     $body = preg_replace("/(^|>)([^<]+)(?=<|$)/sUe", "_highlight('2', $karr[$key], $kaarr[$key], '1')", $body);     //echo $body."<br/>";     //恢复超链接     $body = preg_replace("/(<a(.*))-]-(.*)-[-(/a>)/isU", '1>3<4', $body);//暂时屏蔽超链接     $body = preg_replace("/(<a(.*))(>)(.*)(<)(/a>)/isU", '1-]-4-[-6', $body);     }     //恢复超链接     $body = preg_replace("/(<a(.*))-]-(.*)-[-(/a>)/isU", '1>3<4', $body);     return $body;     }     }     //End Archives     //高亮专用, 替换多次是可能不能达到最多次     function _highlight($string, $words, $result, $pre)     {     global $cfg_replace_num;     $string = str_replace('"', '"', $string); if($GLOBALS['replaced'][$words] == 1){     return $pre.$string;     } if($cfg_replace_num > 0){     $string = preg_replace("/".preg_quote($words)."/", $result, $string, $cfg_replace_num);     if(strpos($string, $words) !== false)     {         $GLOBALS['replaced'][$words] = 1;         }         } else{$string = str_replace($words, $result, $string); } return $pre.$string; }
 
替换完成后保存即可，然后重新生成整站
