dedecms关键词维护里面字数多的词优先字数少的词的解决办法

2023/03/11 10:14     创新屋收录网     已浏览290次

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？下面就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：




















01
function ReplaceKeyword($kw,&$body)











02
    {











03
        global $cfg_cmspath;











04
        $maxkey = 5;











05
        $kws = explode(",",trim($kw));    //以分好为间隔符











06
        $i=0;











07
        $karr = $kaarr = $GLOBALS['replaced'] = array();











08
 











09
        //暂时屏蔽超链接











10
        $body = preg_replace("#()(.*)(<)(/a>)#isU", '\1-]-\4-[-\6', $body);











11
 











12
        /*











13
        foreach($kws as $k)











14
        {











15
            $k = trim($k);











16
            if($k!="")











17
            {











18
                if($i > $maxkey)











19
                {











20
                    break;











21
                }











22
                $myrow = $this->dsql->GetOne("SELECT * FROM #【分隔符】@__keywords WHERE keyword='$k' AND rpurl<>'' ");











23
                if(is_array($myrow))











24
                {











25
                    $karr[] = $k;











26
                    $GLOBALS['replaced'][$k] = 0;











27
                    $kaarr[] = "$k";











28
                }











29
                $i++;











30
            }











31
        }











32
        */











33
        $query = "SELECT * FROM #【分隔符】@__keywords WHERE rpurl<>'' ORDER BY rank DESC";











34
        $this->dsql->SetQuery($query);











35
        $this->dsql->Execute();











36
        while($row = $this->dsql->GetArray())











37
        {











38
            $key = trim($row['keyword']);











39
            $key_url=trim($row['rpurl']);











40
            $karr[] = $key;











41
            $kaarr[] = "$key";











42
        }











43
 











44
        // 这里可能会有错误











45
        $body = @preg_replace("#(^|>)([^<]+)(?=<|$)#sUe", "_highlight('\2', $karr, $kaarr, '\1')", $body);











46
 











47
        //恢复超链接











48
        $body = preg_replace("#()#isU", '\1>\3<\4', $body);











49
        return $body;











50
    }






注意查找代码的时候先手动去掉代码里面的【分隔符】字样！



找到后将其替换为如下代码：




















01
    function ReplaceKeyword($kw,&$body)











02
    {











03
    global $cfg_cmspath,$dsql;











04
    $maxkey = 5;











05
    $kws = explode(",",trim($kw)); //以分好为间隔符











06
    $i=0;











07
    $karr = $kaarr = $GLOBALS['replaced'] = array();











08
    //暂时屏蔽超链接











09
    $body = preg_replace("/()(.*)(<)(/a>)/isU", '\1-]-\4-[-\6', $body);











10
    $query="SELECT * FROM #【分隔符】@__keywords WHERE rpurl<>'' and sta=1 ORDER BY length(keyword)desc";











11
    $dsql->SetQuery($query);











12
    $dsql->Execute();











13
    while($row = $dsql->GetArray())











14
    {











15
    $key = trim($row['keyword']);











16
    $key_url=trim($row['rpurl']);











17
    $karr[] = $key;











18
    $kaarr[] = "$key";











19
    }











20
    foreach ($karr as $key => $word)











21
    {











22
    $body = preg_replace("/(^|>)([^<]+)(?=<|$)/sUe", "_highlight('\2', $karr[$key], $kaarr[$key],











23
 











24
 











25
'\1')", $body);











26
    //echo $body."
";











27
    //恢复超链接











28
    $body = preg_replace("/()/isU", '\1>\3<\4', $body);//暂时屏蔽超链接











29
    $body = preg_replace("/()(.*)(<)(/a>)/isU", '\1-]-\4-[-\6', $body);











30
    }











31
    //恢复超链接











32
    $body = preg_replace("/()/isU", '\1>\3<\4', $body);











33
 











34
 











35
    return $body;











36
    }











37
    }











38
    //End Archives











39
    //高亮专用, 替换多次是可能不能达到最多次











40
    function _highlight($string, $words, $result, $pre)











41
    {











42
    global $cfg_replace_num;











43
    $string = str_replace('"', '"', $string);











44
if($GLOBALS['replaced'][$words] == 1){











45
    return $pre.$string;











46
    }











47
if($cfg_replace_num > 0){











48
    $string = preg_replace("/".preg_quote($words)."/", $result, $string, $cfg_replace_num);











49
    if(strpos($string, $words) !== false)











50
    {











51
        $GLOBALS['replaced'][$words] = 1;











52
        }











53
        }











54
else{$string = str_replace($words, $result, $string);











55
}











56
return $pre.$string;











57
}






注意手动去掉代码里面的【分隔符】字样！



 





替换完成后保存即可，然后生成一下文章内容试试。
