织梦关键词长短优先级问题
比如有“长词”、“我是大长词”、“我是小长词”,同时在一篇文章中出现,程序会优先使用短的词。
解决关键词长短优先级问题的方法
打开 /include/arc.archives.class.php 找到
$query = "SELECT * FROM dede_keywords WHERE rpurl<>'' ORDER BY rank DESC";
改成
$query = "SELECT char_length(keyword) AS num,aid,keyword,rpurl,rank FROM dede_keywords WHERE rpurl<>'' ORDER BY num DESC";
继续找到
"#".preg_quote($word)."#"
改成
"#(?<!>)(?!<)".preg_quote($word)."#"
完成
PHP版本高于5.5无法使用关键词內链的解决方法
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 dede_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 dede_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>", $body); } }
继续找到
//高亮专用
在它上面加入
//指定替换次数功能 function str_replace_limit($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); }
