相信经常使用dedecms的朋友遇到过这样的问题。例如,我在文档关键词中设置锚文本链接的时候,“站长基地”与“站长”同时都指向于http://www.genban.org。当文档中出现站长基地的时候,这时只有“站长”含有链接,而我们希望的则是“站长基地”带有链接,那么如何解决呢?教程如下:
解决方法(先备份)
第一步:打开目录include中的arc.archivew.class.php
找到以下代码:
- function ReplaceKeyword($kw,&$body)
从这里然后一直到最下面。替换这段代码:
- 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);
- global $dsql;
- $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;
- //echo $words;
- }
- }
- else
- {
- $string = str_replace($words, $result, $string);
- }
- return $pre.$string;
- }
