WordPre 5禁止编辑器自动添加noopener noreferrer

因为本站使用了go跳转链接，为安全方面考虑需添加referrer判断合法来源，$_SERVER[HTTP_REFERER]一直取不到值，原因是因为所以链接编辑器自动添加了“noopener noreferrer”属性，应该是WordPress 5.1 版本之后强制为每一个外部链接添加“noopener noreferrer”属性。为禁止编辑器自动为外部链接添加“noopener noreferrer”属性可以使用以下方法添加到当前主题的functions.php文件中：

方法 1：禁止自动添加 noopener noreferrer

add_filter( <span class="hljs-string">wp_targeted_link_rel</span>, <span class="hljs-string">my_targeted_link_rel_remove_noreferrer</span>,<span class="hljs-number">999</span>);

方法 2：禁止自动添加 noopener noreferrer

<span class="hljs-comment">//仅移除前端 noreferrer，编辑器中依然存在</span>
add_filter(<span class="hljs-string">the_content</span>, <span class="hljs-string">my_formatter</span>, <span class="hljs-number">999</span>);

$new_content = strtr($content, $replace);
<span class="hljs-keyword">return</span> $new_content;
}

以前添加的rel=”noopener noreferrer”属性怎么去除?

登录phpmyadmin执行sql语句:

<span class="hljs-keyword">UPDATE</span> wp_posts <span class="hljs-keyword">SET</span> post_content = <span class="hljs-keyword">REPLACE</span>( post_content, <span class="hljs-string">noopener noreferrer</span>, <span class="hljs-string"></span> )
<span class="hljs-keyword">UPDATE</span> wp_posts <span class="hljs-keyword">SET</span> post_content = <span class="hljs-keyword">REPLACE</span>( post_content, <span class="hljs-string">noopener noreferrer</span>, <span class="hljs-string"></span> )
UPDATE wp_posts SET post_content = REPLACE( post_content, noopener noreferrer,  )

特别提醒：执行前切记备份数据库！！！
