相信经常使用 织梦dedecms的朋友遇到过这样的问题。例如,我在文档关键词中设置锚文本链接的时候,“站长基地”与“站长”同时都指向于http://www. ldhost.cn。
当文档中出现站长基地的时候,这时只有“站长”含有链接,而我们希望的则是“站长基地”带有链接,那么如何解决呢? 教程如下:
解决方法(先备份)
第一步:打开目录include中的arc.archivew.class.php
找到以下代码:
function ReplaceKeyword($kw,&$body)
从这里然后一直到最下面。替换这段代码:
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);
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;
$kaarr[] = "<u><a href='$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;
//echo $words;
}
}
else
{
$string = str_replace($words, $result, $string);
}
return $pre.$string;
}
进入后台生成,至此大功告成。
