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？下面就告诉大伙具体的解决方法：
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[ eplaced] = array(); //暂时屏蔽超链接 $body = preg_replace("#()(.*)()#isU", \\1-]-\\4-[-\\6, $body); /* foreach($kws as $k) { $k = trim($k); if($k!="") {if($i > $maxkey){break;}$myrow = $this->dsql->GetOne("SELECT * FROM #【分隔符】@__keywords WHERE keyword=$k AND rpurl\ ");if(is_array($myrow)){$karr[] = $k;$GLOBALS[ eplaced][$k] = 0;$kaarr[] = "$k";}$i++; } } */ $query = "SELECT * FROM #【分隔符】@__keywords WHERE rpurl\ ORDER BY rank DESC"; $this->dsql->SetQuery($query); $this->dsql->Execute(); while($row = $this->dsql->GetArray()) { $key = trim($row[keyword]); /a/dedejq/$key_url=trim($row[ purl]); $karr[] = $key; $kaarr[] = "$key"; } // 这里可能会有错误 $body = @preg_replace("#(^|>)([^<]+)(?=<|$)#sUe", "_highlight(\\2, \$karr, \$kaarr, \\1)", $body); //恢复超链接 $body = preg_replace("#()#isU", \\1>\\3<\\4, $body); return $body; }
注意查找代码的时候先手动去掉代码里面的【分隔符】字样！
找到后将其替换为如下代码：
function ReplaceKeyword($kw,&$body) { global $cfg_cmspath,$dsql; $maxkey = 5; $kws = explode(",",trim($kw)); //以分好为间隔符 $i=0; $karr = $kaarr = $GLOBALS[ eplaced] = array(); //暂时屏蔽超链接 $body = preg_replace("/()(.*)()/isU", \\1-]-\\4-[-\\6, $body); $query="SELECT * FROM #【分隔符】@__keywords WHERE rpurl\ and sta=1 ORDER BY length(keyword)desc"; $dsql->SetQuery($query); $dsql->Execute(); while($row = $dsql->GetArray()) { $key = trim($row[keyword]); /a/dedejq/$key_url=trim($row[ purl]); $karr[] = $key; $kaarr[] = "$key"; } foreach ($karr as $key => $word) { $body = preg_replace("/(^|>)([^<]+)(?=<|$)/sUe", "_highlight(\\2, \$karr[$key], \$kaarr[$key],\\1)", $body); //echo $body."
"; //恢复超链接 $body = preg_replace("/()/isU", \\1>\\3<\\4, $body);//暂时屏蔽超链接 $body = preg_replace("/()(.*)()/isU", \\1-]-\\4-[-\\6, $body); } //恢复超链接 $body = preg_replace("/()/isU", \\1>\\3 0){ $string = preg_replace("/".preg_quote($words)."/", $result, $string, $cfg_replace_num); if(strpos($string, $words) !== false) { $GLOBALS[ eplaced][$words] = 1; } }else{$string = str_replace($words, $result, $string);}return $pre.$string;}
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。
