1 外链转成内链优势
WordPress如何将外链转内链?
文章外链自动转成内链代码
有时候我们因为做谷歌SEO排名,在WordPress网站分享一些被中国网络封锁的海外网站或论坛,这样的链接有被墙风险。
innity_adZoneAsync.q.push(function(){innity_adZoneAsync.display(“ee389847678a3a9d1ce9e4ca69200d06″,”96572”,{“target”:”div-ad-innity-96572/0″,”origin”:”MY”});});
所以,我们要将文章中某些外链自动转换成内链。
WordPress文章外链自动转成内链的代码,有2个版本:
将以下 PHP 代码保存为 go.php 并上传到网站根目录。

innity_adZoneAsync.q.push(function(){innity_adZoneAsync.display(“ee389847678a3a9d1ce9e4ca69200d06″,”96574”,{“target”:”div-ad-innity-96574/0″,”origin”:”MY”});});
PHP 版本和 JS 版本的功能是一样的,区别在于:
注意:如果测试JS版本的跳转代码无效,就用PHP的跳转代码。
上传跳转页面后,接着就是将外链跳转代码,添加到WordPress主题的 function.php 文件里。
2 选 1 代码:
// 外链跳转无加密go.html?url
add_filter('the_content','link_to_jump',999);
function link_to_jump($content){
preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$content,$matches);
if($matches){
foreach($matches[2]
as $val){
if(strpos($val,'://')!==false && strpos($val,home_url())===false&& strpos($val,'wordpressx.com')===false
&& strpos($val,'ufo.org.in')===false && strpos($val,'etufo.org')===false && !preg_match('/.(jpg|jepg|png|ico|bmp|gif|tiff)/i',$val) && !preg_match('/(ed2k|thunder|Flashget|flashget|qqdl):///i',$val))
{
$content=str_replace("href="$val"", "rel="nofollow" target="_blank" href="go.html?url=$val" ",$content);
}
}
}
return $content;
}
// 外链跳转base64加密go.html?url add_filter('the_content','link_to_jump',999); function link_to_jump($content){ preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$content,$matches); if($matches){ foreach($matches[2] as $val){ if(strpos($val,'://')!==false && strpos($val,home_url())===false && strpos($val,'wordpressx.com')===false && strpos($val,'ufo.org.in')===false && strpos($val,'etufo.org')===false && !preg_match('/.(jpg|jepg|png|ico|bmp|gif|tiff)/i',$val) && !preg_match('/(ed2k|thunder|Flashget|flashget|qqdl):///i',$val)) { $content=str_replace("href="$val"", "rel="nofollow" target="_blank" href="go.html?url=" .base64_encode($val). "" ",$content); } } } return $content; }
排除指定某个外链域名不自动转成内链(域名白名单):
&& strpos($val,'你的域名')===false
为了避免搜索引擎蜘蛛抓取到跳转链接,我们可以 robots.txt 文件里,添加禁止搜索引擎蜘蛛抓取的规则:
User-agent: * Disallow: /go.html?url=* Disallow: /go.php?url=*
