纯代码实现WordPress文章内容回复可见

<?php
function reply_to_read($atts, $content=null) {
extract(shortcode_atts(array("notice" => '<p class="reply-to-read">温馨提示: 此处内容需要<a href="#respond" title="评论本文">评论本文</a>后才能查看.</p>'), $atts));
$email = null;
$user_ID = (int) wp_get_current_user()->ID;
if ($user_ID > 0) {
$email = get_userdata($user_ID)->user_email;
//对博主直接显示内容 
$admin_email = test@test.com; //Email地址,更换为你自己的 
if ($email == $admin_email) {
return $content;
}
} else if (isset($_COOKIE['comment_author_email_' . COOKIEHASH])) {
$email = str_replace('%40', '@', $_COOKIE['comment_author_email_' . COOKIEHASH]);
} else {
return $notice;
}
if (empty($email)) {
return $notice;
}
global $wpdb;
$post_id = get_the_ID();
$query = "SELECT `comment_ID` FROM {$wpdb->comments} WHERE `comment_post_ID`={$post_id} and `comment_approved`='1' and `comment_author_email`='{$email}' LIMIT 1";
if ($wpdb->get_results($query)) {
return do_shortcode($content);
} else {
return $notice;
}
} 

add_shortcode('reply', 'reply_to_read'); 
?>

编辑文章时调用格式如下：

[ reply]评论后可见的内容[ /reply] 或者 [ reply notice="自定义的提示信息"]评论后可见的内容[ /reply]

复制代码后，记得手动把reply 和 /reply前面的空格删掉！

[reply]111[/reply] 或者 [reply notice="333"]222[/reply]
