禁止wp更新 : open file "wordpress\wp-includes\update.php".

add_filter('pre_site_transient_update_core',    create_function('$a', "return null;")); // 关闭核心提示

add_filter('pre_site_transient_update_plugins', create_function('$a', "return null;")); // 关闭插件提示

add_filter('pre_site_transient_update_themes',  create_function('$a', "return null;")); // 关闭主题提示

remove_action('admin_init', '_maybe_update_core');    // 禁止 WordPress 检查更新

remove_action('admin_init', '_maybe_update_plugins'); // 禁止 WordPress 更新插件

remove_action('admin_init', '_maybe_update_themes');  // 禁止 WordPress 更新主题




将下面的代码添加到当前主题的 functions.php 文件，即可禁用所有页面的评论功能：
function disable_page_comments( $posts ) {
	if ( is_page()) {
	$posts[0]->comment_status = 'disabled';
	$posts[0]->ping_status = 'disabled';
}
return $posts;
}
add_filter( 'the_posts', 'disable_page_comments' );




禁用及删除版本修订历史
版本修订历史在每一次编辑文章过后，都会自动保留一份，这样的话很容易造成数据的重复储存，占用不必要的资源。
打开wp-config.php，在末尾添加
define('WP_POST_REVISIONS', false);




禁用自动保存
在wp-admin目录，打开post.php、page.php、post-new.php和page-new.php，查找

wp_enqueue_script('autosave');

替换为

//wp_enqueue_script('autosave');





禁用自动草稿

在wp-admin/includes目录，打开post.php，查找

if ( $create_in_db ) {
$post_id = wp_insert_post( array( 'post_title' => __( 'Auto Draft' ), 'post_type' => $post_type, 'post_status' => 'auto-draft' ) );
$post = get_post( $post_id );
if ( current_theme_supports( 'post-formats' ) && post_type_supports( $post->post_type, 'post-formats' ) && get_option( 'default_post_format' ) )
set_post_format( $post, get_option( 'default_post_format' ) );
}

替换为

if ( $create_in_db ) {
global $current_user;
$post = $wpdb->get_row( "SELECT * FROM $wpdb->posts WHERE post_status = 'auto-draft' AND post_type = '$post_type' AND post_author = $current_user->ID ORDER BY ID ASC LIMIT 1" );
if ( !$post ) {
$post_id = wp_insert_post( array( 'post_title' => __( 'Auto Draft' ), 'post_type' => $post_type, 'post_status' => 'auto-draft' ) );
$post = get_post( $post_id );
}
if ( current_theme_supports( 'post-formats' ) && post_type_supports( $post->post_type, 'post-formats' ) && get_option( 'default_post_format' ) )
set_post_format( $post, get_option( 'default_post_format' ) );
}
