wordpress网站外链自动转内链代码

1，自动给文章的外链转内链并添加nofollow属性，将如下代码加到wordpress主题文件夹下function.php文件里：

/*
*自动给文章的外部链接添加nofollow属性
*/ 
add_filter('the_content','web589_the_content_nofollow',999);
function web589_the_content_nofollow($content){
 preg_match_all('/href="(http.*?)"/',$content,$matches);
 if($matches){
 foreach($matches[1] as $val){
 if( strpos($val,home_url())===false ) 
 $content=str_replace("href=\"$val\"", "rel=\"nofollow\" href=\"" . get_bloginfo('wpurl'). "/go?url=" .base64_encode($val). "\"",$content);
 }
 }
 return $content;
}

2，跳go内链，在网站根目录下创建名为”go“的文件夹，在go文件夹下创建index.php文件，并在文件里写入如下代码：

<?php 
$url = $_GET['url'];
$a = '';
if( $a==$url ) {
 $b = "https://www.网站.com/";
// echo 'true';
} else {
 $b = $url;
 $b = base64_decode($b);
}
//Template Name:链接跳转（有过度）
?>
 
<html>
<head>
<meta charset=utf-8 />
<meta name="robots" content="nofollow">
<meta http-equiv="refresh" content="0.1;url=<?php echo $b; ?>">
<title>正在为您跳转……</title>
