Wordpress实现go.php外链跳转二

类似http://www.***.com/go.php?url=http://www.******.com形式的跳转链接，这样是为了站点的SEO能够对各种搜索引擎更友好，更重要的是起到了保护自己域名权重的目的。而在前两天刚给大家介绍了一个，但是有人觉得不太好看，因此今天来分享新的样式，点此体验。

第一步：

复制下面的代码，新建一个.txt 粘贴保存，将文件重新命名为go.php，上传到根目录中或者下载go2.php.zip文件，解压后上传go.php到wordpress根目录下，点击此处下载go2.php.zip文件

提示：小程序点击【点击此处下载go2.php.zip文件】后打开浏览器，粘贴链接进入下载


<?php 
$t_url = preg_replace('/^url=(.*)$/i','$1',$_SERVER["QUERY_STRING"]);
if(!empty($t_url)) {
	preg_match('/(http|https):\/\//',$t_url,$matches);
	if($matches){
		$url=$t_url;
		$title='页面加载中,请稍候...';
	} else {
		$title='加载中...';
		echo "<script>setTimeout(function(){window.opener=null;window.close();}, 9000);</script>";
	}
}
?>
<html>

</head>
<body>
<div class="pageLoading">
<div class="monster">
<div class="eye">
<div class="eyeball"></div>
</div>
<div class="mouth"></div>
</div><h2>正在加载中...</h2>
<div class="loading">
<div class="bar"></div>
</div>
</div>
<script>
var percent = 0
var timer = setInterval(function(){
 document.querySelector(".bar").style.setProperty("width",percent+"%")
  percent+=1
},30)
</script>
</body>
</html>

第二步：

复制下面的代码到wordpress主题functions.php中，或者下载上面的go.php.zip文件，解压后将functions.php替代wordpress主题functions.php

/**
* WordPress实现go.php外链跳转
* https://mznzd.com/ted/249.htmll
*/
//给外部链接加上go跳转
add_filter('the_content','the_content_nofollow',999);
function the_content_nofollow($content)
{
preg_match_all('/<a(.*?)href="(.*?)"(.*?)>/',$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)){
$content=str_replace("href=\"$val\"", "href=\"".home_url()."/go.php?url=$val\" ",$content);
}
}
}
return $content;
}

完成上面两步，只需要在文章插入外链就可以啦，点击链接的效果如下图。
