,让系统自动把外链都加上nofollow属性,修改方法如下：,,1. 打开目录source/function/function_discuzcode.php文件，查找parseurl函数，对照以下代码进行修改：,
function parseurl($url, $text, $scheme) {
global $_G;
if(!$url && preg_match("/((https?|ftp|gopher|news|telnet|rtsp|mms|callto|bctp|thunder|qqdl|synacast){1}:\/\/|www\.)[^\[\"']+/i", trim($text), $matches)) {
$url = $matches[0];
$length = 65;
if(strlen($url) > $length) {
$text = substr($url, 0, intval($length * 0.5)).' ... '.substr($url, - intval($length * 0.3));
}
$url = nofollow($url);
return ''.$text.'';
} else {
$url = substr($url, 1);
if(substr(strtolower($url), 0, 4) == 'www.') {
$url = 'http://'.$url;
}
$url = !$scheme ? $_G['siteurl'].$url : $url;
return ''.$text.'';
}
}
,复制代码,,2. 在parseurl函数后面新增nofollow函数，代码如下：,
function nofollow($url = '')
{
$temp = array();
if( ! empty($url))
{
$temp = parse_url($url);
if(isset($temp['host']) && $temp['host'] != $_SERVER['HTTP_HOST'])
{
$url .= '" rel="nofollow"';
}
}
unset($temp);
return $url;
}
