去除WordPress header 的 link 标签 rel 属性

WordPress 在 2.8 版本之后,增加了几个新的 link 标签 rel 属性,例如:

<link rel="index" title="Sino Blog" href="http://www.sinoblog.org" />
<link rel="start" title="Hello World" href="http://www.sinoblog.org/2007/09/hello-world.html" />
<link rel="prev" title="QQ邮箱支持域名邮箱个性化邮件服务" href="http://www.sinoblog.org/2009/09/qq-domainmail.html" />

如果要去掉 WordPress 博客 header 部分的这些 rel 属性,可以通过修改主题支持函数(functions.php)来实现,规则是:

remove_action( $tag, $function_to_add, $priority, $accepted_args );

例如,要去掉下面的这些 link 标签:

<link rel="alternate" type="application/rss+xml" title="WP Engineer RSS Feed" href="http://www.aliyoga.com/yujia/feed/" />
<link rel="alternate" type="application/atom+xml" title="WP Engineer Atom Feed" href="http://www.aliyoga.com/yujia/feed/atom/" />
<link rel="pingback" href="http://www.aliyoga.com/yujia/xmlrpc.php" />
<link rel="EditURI" type="application/rsd+xml" title="RSD" href="http://www.aliyoga.com/xmlrpc.php?rsd" />
<link rel="index" title="WP Engineer" href="http://www.aliyoga.com" />
<link rel="start" title="Use WordPress 2.7 Offline" href="http://www.aliyoga.com/shop/" />
<link rel="prev" title="Recents Drafts All Authors" href="http://www.aliyoga.com/bbs/" />

分别对应的 remove_action 代码是:

remove_action( 'wp_head', 'feed_links_extra', 3 ); // Display the links to the extra feeds such as category feeds
remove_action( 'wp_head', 'feed_links', 2 ); // Display the links to the general feeds: Post and Comment Feed
remove_action( 'wp_head', 'rsd_link' ); // Display the link to the Really Simple Discovery service endpoint, EditURI link
remove_action( 'wp_head', 'wlwmanifest_link' ); // Display the link to the Windows Live Writer manifest file.
remove_action( 'wp_head', 'index_rel_link' ); // index link
remove_action( 'wp_head', 'parent_post_rel_link', 10, 0 ); // prev link
remove_action( 'wp_head', 'start_post_rel_link', 10, 0 ); // start link
remove_action( 'wp_head', 'adjacent_posts_rel_link', 10, 0 ); // Display relational links for the posts adjacent to the current post.
remove_action( 'wp_head', 'wp_generator' ); // Display the XHTML generator that is generated on the wp_head hook, WP version
