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

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(.*))(>)(.*)(<)(\/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
										
											                    $kaarr[] = "<a href='{$myrow['rpurl']}'><u>$k</u></a>";
									
											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
										
											            $kaarr[] = "<a href='$key_url' target='_blank'><u>$key</u></a>";
									
											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("#(<a(.*))-\]-(.*)-\[-(\/a>)#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(.*))(>)(.*)(<)(\/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
										
											    $kaarr[] = "<u><a href='$key_url' target='_blank'>$key</a></u>";
									
											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."<br/>";
									
											27
										
											    //恢复超链接
									
											28
										
											    $body = preg_replace("/(<a(.*))-\]-(.*)-\[-(\/a>)/isU", '\\1>\\3<\\4', $body);//暂时屏蔽超链接
									
											29
										
											    $body = preg_replace("/(<a(.*))(>)(.*)(<)(\/a>)/isU", '\\1-]-\\4-[-\\6', $body);
									
											30
										
											    }
									
											31
										
											    //恢复超链接
									
											32
										
											    $body = preg_replace("/(<a(.*))-\]-(.*)-\[-(\/a>)/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。
