织梦dedecms自动给文章中的关键字加超链接完整版 。
在 include/arc.archives.class.php 这个文件中 有两个函数需要修改 ReplaceKeyword 和 _highlight 把这两个函数 第1014行开始到倒数第二行结束 修改为 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", '-]--[-', $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; $kaarr[] = "<b><a href='$key_url' target='_blank'>$key</a></b>"; } foreach ($karr as $key => $word) { $body = preg_replace("/(^|>)([^<]+)(?=<|$)/sUe", "_highlight('', $karr[$key], $kaarr[$key], '')", $body); //echo $body."<br/>"; //恢复超链接 $body = preg_replace("/(<a(.*))-]-(.*)-[-(/a>)/isU", '><', $body); //暂时屏蔽超链接 $body = preg_replace("/(<a(.*))(>)(.*)(<)(/a>)/isU", '-]--[-', $body); } //恢复超链接 $body = preg_replace("/(<a(.*))-]-(.*)-[-(/a>)/isU", '><', $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; } 保存替换就可以了。
