我需要有条件地不显示评论表单。

我已将筛选器添加到comment_form_defaults 具体如下：

function dont_show_comments($defaults) {
  $defaults = array(
    \'fields\'               => array(),
    \'comment_field\' => \'\',
    \'must_log_in\'          => \'<p class="must-log-in">\' .  sprintf( __( \'You must be <a href="%s">logged in</a> to post a comment.\' ), wp_login_url( apply_filters( \'the_permalink\', get_permalink( $post_id ) ) ) ) . \'</p>\',
    \'logged_in_as\'         => \'\',
    \'comment_notes_before\' => \'\',
    \'comment_notes_after\'  => \'\',
    \'id_form\'              => \'commentform\',
    \'id_submit\'            => \'hide\',
    \'title_reply\'          => __( \'You need to have accepted the terms to leave a reply\' ),
    \'title_reply_to\'       => __( \'Leave a Reply %s\' ),
    \'cancel_reply_link\'    => __( \'Cancel reply\' ),
    \'label_submit\'         => \'\',
   );

return $defaults;
}

不显示表单的最佳方式是什么？最好是通过挂钩，最好不要使用CSS。
