WordPress主题子比主题添加私密评论功能

给你的网站添加一个私密评论功能，该教程几乎适配99%的WordPress主题，这里以子比主题为例。

教程如下

//私密评论
function liao_private_message_hook( $comment_content , $comment){
$comment_ID = $comment->comment_ID;
$parent_ID = $comment->comment_parent;
$parent_email = get_comment_author_email($parent_ID);
$is_private = get_comment_meta($comment_ID,'_private',true);
$email = $comment->comment_author_email;
$current_commenter = wp_get_current_commenter();
if ( $is_private ) $comment_content = '#私密# ' . $comment_content;
if ( $current_commenter['comment_author_email'] == $email || $parent_email == $current_commenter['comment_author_email'] || current_user_can('delete_user') ) return $comment_content;
if ( $is_private ) return '<span style="color:#A6A6A6"><i class="fa fa-lock fa-fw"></i>该评论为私密评论</span>';
return $comment_content;
}
add_filter('get_comment_text','liao_private_message_hook',10,2);
function liao_mark_private_message( $comment_id ){
if ( $_POST['is-private'] ) {
update_comment_meta($comment_id,'_private','true');
}
}
add_action('comment_post', 'liao_mark_private_message');

打开子比主题的 comments.php 文件，搜索提交评论，在其上方添加下方代码之后保存即可。(如图)
文件路径：/wp-content/themes/zibll/template/comments.php

<label class="but c-blue pw-1em" data-placement="top" data-toggle="tooltip" title="" style="margin-bottom: 0px; overflow: hidden; position: relative;" data-original-title="你的评论仅评论双方可见。">
<input name="is-private" type="checkbox">私密评论</label>
