名站网址导航为大驾家提供DedeCMS站点程序站点教程相关的知识，比如织梦程序安装教程,织梦程序系统故障等教程。织梦程序网站的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，比如咱们有两个这样的词：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，那么咱们怎么样才能实现字数多的词优先于字数少的词呢？下面就告诉大驾家具体的解决相关具体操作方法：
咱们找到并打开/include/arc.archives.class.php网站文件，在里面找到如下相关具体代码如下：
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;
$kaarr[] = "<a href='{$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;
$kaarr[] = "<a href='$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(.*))-\]-(.*)-\[-(\/a>)#isU", '\\1>\\3<\\4', $body);
return $body;
}
|
注意查找相关具体代码如下的时候先手动去掉相关具体代码如下里面的【分隔符】字样！
找到后将其替换为如下相关具体代码如下：
function ReplaceKeyword($kw,&$body)
{
global $cfg_cmspath,$dsql;
$maxkey = 5;
$kws = explode(",",trim($kw)); //以分好为间隔符
$i=0;
$karr = $kaarr = $GLOBALS['replaced'] = array();
//暂时屏蔽超链接
$body = preg_replace("/(<a(.*))(>)(.*)(<)(\/a>)/isU", '\\1-]-\\4-[-\\6', $body);
$query="SELECT * FROM #【分隔符】@__keywords WhERE rpurl<>'' and sta=1 ORDER BY length(keyword)desc";
$dsql->SetQuery($query);
$dsql->Execute();
while($row = $dsql->GetArray())
{
$key = trim($row['keyword']);
$key_url=trim($row['rpurl']);
$karr[] = $key;
$kaarr[] = "<u><a href='$key_url' target='_blank'>$key</a></u>";
}
foreach ($karr as $key => $word)
{
$body = preg_replace("/(^|>)([^<] )(?=<|$)/sUe", "_highlight('\\2', \$karr[$key], \$kaarr[$key],
'\\1')", $body);
//echo $body."<br/>";
//恢复超链接
$body = preg_replace("/(<a(.*))-\]-(.*)-\[-(\/a>)/isU", '\\1>\\3<\\4', $body);//暂时屏蔽超链接
$body = preg_replace("/(<a(.*))(>)(.*)(<)(\/a>)/isU", '\\1-]-\\4-[-\\6', $body);
}
//恢复超链接
$body = preg_replace("/(<a(.*))-\]-(.*)-\[-(\/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;
} |
注意手动去掉相关具体代码如下里面的【分隔符】字样！
