我们在使用一些 wordpress 插件的时候，经常会在页面的顶部，也就是网页的 head 之间产生一些插件代码，当不使用这些插件的时候，会产生冗余代码，从而导致一些插件不能正常的使用问题，怎样才能将这些代码进行批量删除掉呢，下面看一段因插件产生的代码清理方法，代码如下:

<?php
//remove_action( "wp_head", "wp_enqueue_scripts", 1 );
remove_action( "wp_head", "feed_links", 2 );
remove_action( "wp_head", "feed_links_extra", 3 );
remove_action( "wp_head", "rsd_link" );
remove_action( "wp_head", "wlwmanifest_link" );
remove_action( "wp_head", "index_rel_link" );
remove_action( "wp_head", "parent_post_rel_link", 10, 0 );
remove_action( "wp_head", "start_post_rel_link", 10, 0 );
remove_action( "wp_head", "adjacent_posts_rel_link_wp_head", 10, 0 );
//remove_action( "wp_head", "locale_stylesheet" );
remove_action( "publish_future_post", "check_and_publish_future_post", 10, 1 );
//remove_action( "wp_head", "noindex", 1 );
//remove_action( "wp_head", "wp_print_styles", 8 );
//remove_action( "wp_head", "wp_print_head_scripts", 9 );
remove_action( "wp_head", "wp_generator" );
//remove_action( "wp_head", "rel_canonical" );
remove_action( "wp_footer", "wp_print_footer_scripts" );
remove_action( "wp_head", "wp_shortlink_wp_head", 10, 0 );
remove_action( "template_redirect", "wp_shortlink_header", 11, 0 );
add_action("widgets_init", "my_remove_recent_comments_style");
function my_remove_recent_comments_style() {
global $wp_widget_factory;
remove_action("wp_head", array($wp_widget_factory->widgets["WP_Widget_Recent_Comments"], "recent_comments_style"));
}
?>

将本代码放入到主题 funtions.php 文件中就可以了。

本方法主要利用了remove_action函数，关于本函数就不多介绍了，如果有兴趣的话可以到wp官网上面看一下。
