瞧，那夕阳边的云霞，好似得到了夕阳的赏赐，变得欣喜异常，时而围坐一团，倾诉衷肠；时而围着夕阳跳起了探戈；更有自我陶醉的，远离他人，自我欣赏……
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，比如我们有两个这样的词：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，那么我们怎么样才能实现字数多的词优先于字数少的词呢？下面就告诉大家具体的解决方法：
我们找到并打开/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['replaced'] = array();
//暂时屏蔽超链接
$body = preg_replace("#(<a(.*))(>)(.*)(<)(\/a>)#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;
$GLOBALS['replaced'][$k] = 0;
$kaarr[] = "<a rel="nofollow noopener noreferrer" href='{$myrow['rpurl']}'><u>$k</u></a>";
}
$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']);
$key_url=trim($row['rpurl']);
$karr[] = $key;
$kaarr[] = "<a rel="nofollow noopener noreferrer" href='$key_url' target='_blank'><u>$key</u></a>";
}
// 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("#(<a(.*))-\]-(.*)-\[-(\/a>)#isU", '\\1>\\3<\\4', $body);
return $body;
}
|
注意查找代码的时候先手动去掉代码里面的【分隔符】字样！
找到后将其替换为如下代码：
function ReplaceKeyword($kw,&$body)
{
global $cfg_cmspath,$dsql;
$maxkey = 5;
$kws = explode(",",trim($kw)); //以分好为间隔符
$i=0;
$karr = $kaarr = $GLOBALS['replaced'] = array();
//暂时屏蔽超链接
$body = preg_replace("/(<a(.*))(>)(.*)(<)(\/a>)/isU", '\\1-]-\\4-[-\\6', $body);
$query="SELECT * FROM #【分隔符】@__keywords WHERE rpurl<>'' and sta=1 ORDER BY length(keyword)desc";
$dsql->SetQuery($query);
$dsql->Execute();
while($row = $dsql->GetArray())
{
$key = trim($row['keyword']);
$key_url=trim($row['rpurl']);
$karr[] = $key;
$kaarr[] = "<u><a rel="nofollow noopener noreferrer" href='$key_url' target='_blank'>$key</a></u>";
}
foreach ($karr as $key => $word)
{
$body = preg_replace("/(^|>)([^<]+)(?=<|$)/sUe", "_highlight('\\2', \$karr[$key], \$kaarr[$key],
'\\1')", $body);
//echo $body."<br/>";
//恢复超链接
$body = preg_replace("/(<a(.*))-\]-(.*)-\[-(\/a>)/isU", '\\1>\\3<\\4', $body);//暂时屏蔽超链接
$body = preg_replace("/(<a(.*))(>)(.*)(<)(\/a>)/isU", '\\1-]-\\4-[-\\6', $body);
}
//恢复超链接
$body = preg_replace("/(<a(.*))-\]-(.*)-\[-(\/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;
}
}
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。
