WordPress手工添加外链转内链的功能（附完整源代码）

2021-1-3 80 1/3

给网站添加外链go提升效果既美观又可避免权重流失，一个简单的SEO优化确实是一个不错的功能。看很多朋友来消息求这个功能，那就是在这里分享一下本站部署的方法和操作，其实也还蛮简单的。
有纯手工修改实现及插件，支持替换页，nofollow，加密原链接功能。

方法一，纯手工修改源代码

纯手工修改源代码Wordpress外链转内链，操作起来略麻烦，并且每次主题更新后得再次操作一遍，适合对源代码有一定经验的朋友，优点是不需要安装插件，内链替代链接美观。

步骤一：

修改主题的functions.php文件，路径为：/网站路径/ wp-content / themes /主题文件夹/functions.php，然后添加以下代码：


add_filter('the_content','baezone_the_go_url',999);
function baezone_the_go_url($content){
preg_match_all('/href="(.*?)"/',$content,$matches);
if($matches){
foreach($matches[1] as $val){
if( strpos($val,home_url())===false ) $content=str_replace("href=\"$val\"", "href=\"" . get_bloginfo('wpurl'). "/go.php?url=" .base64_encode($val). "\"",$content);
}
}
return $content;
}

步骤二：

在网站根目录新建一个go.php文件，并输入如下内容并保存。

直接下载go.php文件：蓝奏云

方法二，Wordpress外链转内链替换插件

使用Wordpress外链转内链替换插件实现外链转内链，操作替换，并且主题升题更换后并不影响功能使用，适合对源代码不懂的小白，缺点是内链替换链接不够美观。

WordPress外链转内链扩展插件下载：蓝奏云 密码：f25d

方法三，Wordpress外链转内链替换插件+手工修改源代码

本方法仅适用于又懒又有强迫症的患者，综合了Wordpress外链转内链替换插件及手工修改方法，实现了不用每次更新主题都重新修改的囧况！

操作步骤

  • 下载WordPress外链转内链插入插件（密码：f25d），上传并安装启用。
  • 面板文件管理下：找到并打开/网站路径/可湿性粉剂内容/插件/ wpgo /目录下的index.php的文件
    或者在WordPress的后台插件编辑器里面找到外链转内链跳转插件，找到并编辑索引.php文件
  • 将“ /wp-content/plugins/wpgo/go.php?url=”修改成“ /go.php?url=”
  • 将go.php文件上传到网站根目录，完成！

其他：关于将文章来源网址也转成内链的方法

如果我们的文章引用于他处，保留了引用来源网站名称和来源网址，如何优化既保留了版权引用又外观，并且SEO优化后不流失权重，修改方法如下，
本站以D8主题为例，其他主题大同小异，参照修改即可。仅
适合上面手工修改方法。

源代码修改：

修改主题的functions.php文件，路径为：/网站路径/ wp-content / themes /主题文件夹/functions.php，找到如下代码：
