这里列出了以上所有答案，并删除了管理栏链接。只需将其添加到您的主题功能文件或将其作为插件即可。我将把它标记为一个社区维基，因为每个人的答案都是正确的，只是没有人将其全部添加到一起。

<?php
// Removes from admin menu
add_action( \'admin_menu\', \'my_remove_admin_menus\' );
function my_remove_admin_menus() {
    remove_menu_page( \'edit-comments.php\' );
}
// Removes from post and pages
add_action(\'init\', \'remove_comment_support\', 100);

function remove_comment_support() {
    remove_post_type_support( \'post\', \'comments\' );
    remove_post_type_support( \'page\', \'comments\' );
}
// Removes from admin bar
function mytheme_admin_bar_render() {
    global $wp_admin_bar;
    $wp_admin_bar->remove_menu(\'comments\');
}
add_action( \'wp_before_admin_bar_render\', \'mytheme_admin_bar_render\' );
?>

要删除“注释”菜单，请执行以下操作：

add_action( \'admin_init\', \'my_remove_admin_menus\' );
function my_remove_admin_menus() {
    remove_menu_page( \'edit-comments.php\' );
}

这将删除对您网站上评论的支持：

add_action(\'admin_menu\', \'remove_comment_support\');

function remove_comment_support() {
    remove_post_type_support( \'post\', \'comments\' );
    remove_post_type_support( \'page\', \'comments\' );
}

// Disable support for comments and trackbacks in post types
function df_disable_comments_post_types_support() {
    $post_types = get_post_types();
    foreach ($post_types as $post_type) {
        if(post_type_supports($post_type, \'comments\')) {
            remove_post_type_support($post_type, \'comments\');
            remove_post_type_support($post_type, \'trackbacks\');
        }
    }
}
add_action(\'admin_init\', \'df_disable_comments_post_types_support\');

// Close comments on the front-end
function df_disable_comments_status() {
    return false;
}
add_filter(\'comments_open\', \'df_disable_comments_status\', 20, 2);
add_filter(\'pings_open\', \'df_disable_comments_status\', 20, 2);

// Hide existing comments
function df_disable_comments_hide_existing_comments($comments) {
    $comments = array();
    return $comments;
}
add_filter(\'comments_array\', \'df_disable_comments_hide_existing_comments\', 10, 2);

// Remove comments page in menu
function df_disable_comments_admin_menu() {
    remove_menu_page(\'edit-comments.php\');
}
add_action(\'admin_menu\', \'df_disable_comments_admin_menu\');

// Redirect any user trying to access comments page
function df_disable_comments_admin_menu_redirect() {
    global $pagenow;
    if ($pagenow === \'edit-comments.php\') {
        wp_redirect(admin_url()); exit;
    }
}
add_action(\'admin_init\', \'df_disable_comments_admin_menu_redirect\');

// Remove comments metabox from dashboard
function df_disable_comments_dashboard() {
    remove_meta_box(\'dashboard_recent_comments\', \'dashboard\', \'normal\');
}
add_action(\'admin_init\', \'df_disable_comments_dashboard\');

// Remove comments links from admin bar
function df_disable_comments_admin_bar() {
    if (is_admin_bar_showing()) {
        remove_action(\'admin_bar_menu\', \'wp_admin_bar_comments_menu\', 60);
    }
}
add_action(\'init\', \'df_disable_comments_admin_bar\');

这不会将其从标记本身中删除，但通过在主题的CSS中添加以下行，可以轻松隐藏WP 3.1管理栏链接（无论是从视觉上还是从屏幕阅读器中）：

li#wp-admin-bar-comments { display: none; visibility: hidden; }

有一种现成的解决方案可以做到这一点。这是Frank Bültge的插件

文档：http://wpengineer.com/2230/removing-comments-absolutely-wordpress/

插件下载：https://github.com/bueltge/Remove-Comments-Absolutely

只需安装即可。无配置。

它与WP 3.5配合使用效果良好
