WordPress文章自动外链go跳转避免权重丢失

在functions.php文件中加入以下代码，这样就可以自动进行外链替换。

/**
* WordPress外链新窗口打开并使用php页面go跳转
* https://www.wuyouw.com
*/
function the_content_nofollow($content){
preg_match_all('/<a(.?)href="(.?)"(.*?)>/',$content,$matches);
if($matches){
foreach($matches[2] as $val){
if(strpos($val,'://')!==false &amp;&amp; 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;
}
add_filter('the_content','the_content_nofollow',999);

但还需要去建立一个外链跳转提示页面模板，跳转的模板这里有三套模板

款式一:

<?php
if(strlen($_SERVER['REQUEST_URI']) > 255 ||
strpos($_SERVER['REQUEST_URI'], "eval(") ||
strpos($_SERVER['REQUEST_URI'], "base64")) {
@header("HTTP/1.1 414 Request-URI Too Long");
@header("Status: 414 Request-URI Too Long");
@header("Connection: Close");
@exit;
}
//通过 QUERY_STRING 取得完整的传入数据，然后取得 url=之后的所有值，兼容性更好
$t_url = preg_replace('/^url=(.*)$/i','$1',$_SERVER["QUERY_STRING"]);
//此处可以自定义一些特别的外链，不需要可以删除以下 5 行
if($t_url=="wuyouw" ) {
$t_url="https://www.wuyouw.com";
} elseif($t_url=="baidu") {
$t_url="https://www.baidu.com/";
}
//数据处理
if(!empty($t_url)) {
//判断取值是否加密
if ($t_url == base64_encode(base64_decode($t_url))) {
$t_url = base64_decode($t_url);
}
//对取值进行网址校验和判断
preg_match('/^(http|https|thunder|qqdl|ed2k|Flashget|qbrowser):///i',$t_url,$matches);
if($matches){
$url=$t_url;
$title='页面加载中,请稍候...';
} else {
preg_match('/./i',$t_url,$matche);
if($matche){
$url='http://'.$t_url;
$title='页面加载中,请稍候...';
} else {
$url = 'http://'.$_SERVER['HTTP_HOST'];
$title='参数错误，正在返回首页...';
}
}
} else {
$title = '参数缺失，正在返回首页...';
$url = 'http://'.$_SERVER['HTTP_HOST'];
}

使用教程:

1.把识别代码放入主题function.php即可

2.然后再根目录下面(wp-content同级，非主题目录)创建一个go文件夹 文件，然后在go文件夹里面再创建一个index.php文件，把以上三种模板任意一种放进index.php里面即可实现外链自动跳转了
