织梦关键词维护里面字数多的词优先字数少的词自动内链

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[&＃39;replaced&＃39;] = array(); //暂时屏蔽超链接 $body = preg_replace("#()(.*)(<)(/a>)#isU", &＃39;1-]-4-[-6&＃39;, $body); /* foreach($kws as $k) { $k = trim($k); if($k!="") { if($i > $maxkey) { break; } $myrow = $this->dsql->GetOne("SELECT * FROM dede_keywords WHERE keyword=&＃39;$k&＃39; AND rpurl<>&＃39;&＃39; "); if(is_array($myrow)) { $karr[] = $k; $GLOBALS[&＃39;replaced&＃39;][$k] = 0; $kaarr[] = "$k"; } $i++; } } */ $query = "SELECT * FROM dede_keywords WHERE rpurl<>&＃39;&＃39; ORDER BY rank DESC"; $this->dsql->SetQuery($query); $this->dsql->Execute(); while($row = $this->dsql->GetArray()) { $key = trim($row[&＃39;keyword&＃39;]); $key_url=trim($row[&＃39;rpurl&＃39;]); $karr[] = $key; $kaarr[] = "$key"; } // 这里可能会有错误 六久阁http://www.lol9.cn $body = @preg_replace("#(^|>)([^<]+)(?=<|$)#sUe", "_highlight(&＃39;2&＃39;, $karr, $kaarr, &＃39;1&＃39;)", $body); //恢复超链接 $body = preg_replace("#()#isU", &＃39;1>3<4&＃39;, $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[&＃39;replaced&＃39;] = array(); //暂时屏蔽超链接 $body = preg_replace("/()(.*)(<)(/a>)/isU", &＃39;1-]-4-[-6&＃39;, $body); $query="SELECT * FROM dede_keywords WHERE rpurl<>&＃39;&＃39; and sta=1 ORDER BY length(keyword)desc"; $dsql->SetQuery($query); $dsql->Execute(); while($row = $dsql->GetArray()) { $key = trim($row[&＃39;keyword&＃39;]); $key_url=trim($row[&＃39;rpurl&＃39;]); $karr[] = $key; $kaarr[] = "$key"; } foreach ($karr as $key => $word) { $body = preg_replace("/(^|>)([^<]+)(?=<|$)/sUe", "_highlight(&＃39;2&＃39;, $karr[$key], $kaarr[$key], &＃39;1&＃39;)", $body); //echo $body."
