WordPress 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

<span class="hljs-comment">//新建或更新文章时移除 noreferrer</span>
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>); 
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">my_targeted_link_rel_remove_noreferrer</span><span class="hljs-params">( $rel_values )</span> </span>{ 
<span class="hljs-keyword">return</span> preg_replace( <span class="hljs-string">'/noreferrers*/i'</span>, <span class="hljs-string">''</span>, $rel_values );

} 

<span class="hljs-comment">//新建或更新文章时移除 noopener</span>

function my_targeted_link_rel_remove_noreferrer( $rel_values ) {

} 

//新建或更新文章时移除 noopener
add_filter( 'wp_targeted_link_rel', 'my_targeted_link_rel_remove_noopener',999); 
function my_targeted_link_rel_remove_noopener( $rel_values ) { 
return preg_replace( '/noopeners*/i', '', $rel_values ); 
}

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>);

$replace = <span class="hljs-keyword">array</span>(<span class="hljs-string">" noreferrer"</span> => <span class="hljs-string">""</span> );
$new_content = strtr($content, $replace);
<span class="hljs-keyword">return</span> $new_content;
}
<span class="hljs-comment">//仅移除前端 noopener，编辑器中依然存在</span>

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

}

//仅移除前端 noopener，编辑器中依然存在
add_filter('the_content', 'noopener_formatter', 999);

}

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！！！
