织梦内链失效(文档关键词维护)解决办法
当PHP版本高于5.5时,织梦DedeCMS无法使用关键词內链,下面是此问题的解决方法。
打开 /include/arc.archives.class.php 找到
$body = @preg_replace_callback("#(^|>)([^<]+)(?=<|$)#sU", "_highlight('\\2', \$karr, \$kaarr, '\\1')", $body); |
改成:
global $cfg_replace_num; if($cfg_replace_num > 0) { $query = "SELECT char_length(keyword) AS num,aid,keyword,rpurl,rank FROM zuola.net_keywords WHERE rpurl<>'' ORDER BY num DESC"; $this->dsql->SetQuery($query); $this->dsql->Execute(); while($row = $this->dsql->GetArray()) { $key = trim($row['keyword']); $key_url=trim($row['rpurl']); $body = str_replace_limit($key, "<a href='$key_url' target='_blank'><u>$key</u></a>", $body, $cfg_replace_num); } } else { $query = "SELECT char_length(keyword) AS num,aid,keyword,rpurl,rank FROM zuola.net_keywords WHERE rpurl<>'' ORDER BY num DESC"; $this->dsql->SetQuery($query); $this->dsql->Execute(); while($row = $this->dsql->GetArray()) { $key = trim($row['keyword']); $key_url=trim($row['rpurl']); $body = str_replace($key, "<a href='$key_url' target='_blank'><u>$key</u></a>", $body); } } |
继续找到:
//高亮专用, 替换多次是可能不能达到最多次 |
在它上面加入:
//指定替换次数功能 function str_replace_limit($search, $replace, $subject, $limit) { if(is_array($search)) { foreach($search as $k=>$v) { $search[$k] = '#(?<!>)(?!<)'. preg_quote($search[$k], '#'). '#'; } } else { $search = '#(?<!>)(?!<)'. preg_quote($search, '#'). '#'; } return preg_replace($search, $replace, $subject, $limit); } |
