文章外链转内链并转入跳转页面,需要两段代码:

Function代码

// 文章外链转内链并转入跳转页面,by minirizhi.com
add_filter('the_content','goto_url',999);
function goto_url($content){
    preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$content,$matches);
    if($matches){
        foreach($matches[2] as $val){
            if(strpos($val,'://')!==false && strpos($val,home_url())===false && !preg_match('/\.(jpg|jepg|png|ico|bmp|gif|tiff)/i',$val) && !preg_match('/(ed2k|thunder|Flashget|flashget|qqdl):\/\//i',$val)){
                $content=str_replace("href=\"$val\"", "rel=\"nofollow\" target=\"_blank\" href=\"" . get_bloginfo('home'). "/goto?url=" .base64_encode($val). "\"",$content);
            }
        }
    }
    return $content;
}

function links_nofollow($url) {
    if(strpos($url,'://')!==false && strpos($url,'echo.net')===false && !preg_match('/(ed2k|thunder|Flashget|flashget|qqdl):\/\//i',$url)) {
    $url = str_replace($url, home_url()."/goto?url=".base64_encode($url),$url);
         }
    return $url;
}

新建goto.php文件,填入页面模版代码,丢入模版文件夹。然后控制后台新建跳转链接页面,内容为空,slug名为goto,选择页面模版,发布即可。
