wordpress给文章内容站外链接添加跳转

发布于 2020-04-14  96 次阅读


方法来自于网上多个文章整合!

在你当前使用的主题的 functions.php 中加入以下代码


// 文章go外链跳转
add_filter('the_content','go_url',999);
function go_url($content){
	preg_match_all('/href="(.*?)"/',$content,$matches);
	if($matches){
		foreach($matches[1] as $val){
			if( strpos($val,home_url())===false&&strpos($val,"javascript:void(0)")===false )
				$content=str_replace("href=\"$val\"", "rel=\"nofollow\" target=\"_blank\" href=\"" . get_bloginfo('wpurl'). "/go?url=" .base64_encode($val). "\"",$content);
		}
	}
	return $content;
}

然后在网站根目录下新建个 go 的文件夹,在其中写个 index.php 的文件,内容如下(请保存为UTF-8):

<?php $url = $_GET['url']; $url = base64_decode($url); ?>
<meta charset="utf-8" />
<meta http-equiv="refresh" content="0.1;url=<?php echo $url; ?>">
跳转页

至此基本上大功告成了,但是如果让跳转页更加好看的,也可以用下面的这个index.php的代码


<?php

$url = $_GET['url'];

$url = base64_decode($url);

?>

<html>

<head>

<meta charset=utf-8 />

<meta name="robots" content="nofollow">

<meta http-equiv="refresh" content="0.1;url=<?php echo $url; ?>">

<title>正在为您跳转……</title>

<style>

尽管代码中已经用 base64 将源链接加密,并且加上了 nofollow,但恐怕蜘蛛还是能爬行,所以干脆一不做二不休,在 Robot s 禁止所有蜘蛛爬行 /go?url 目录吧!
