WordPress邮件提醒的用法

WordPress主题站可以使用邮件提醒的功能项目，一般都是用在开发者登录或者用户登录需要发送邮件的情况，但我们今天教大家的是如何在文章评论回复后实现自动的邮件提醒创造者的方法：

首先将下面代码修改后复制到functions.php文件，再测试发送邮件功能。

//评论回复邮件

function comment_mail_notify($comment_id) {

$comment = get_comment($comment_id);

$parent_id = $comment->comment_parent ? $comment->comment_parent : '';

$spam_confirmed = $comment->comment_approved;

if (($parent_id != '') && ($spam_confirmed != 'spam')) {

$wp_email = 'no-reply@' . preg_replace('#^www\.#', '', strtolower($_SERVER['SERVER_NAME']));//发件人e-mail地址

$to = trim(get_comment($parent_id)->comment_author_email);

$subject = '您在 [' . get_option("blogname") . '] 的留言有了回应';

$message = '<div style="border-right:#666666 1px solid;border-radius:8px;color:#111;font-size:12px;width:702px;border-bottom:#666666 1px solid;font-family:微软雅黑,arial;margin:10px auto 0px;border-top:#666666 1px solid;border-left:#666666 1px solid"><div class="adM">

'" rel="external nofollow" rel="external nofollow" target="_blank">' . get_option('blogname') . '</a> 上的留言有回复啦！</span> </div>

<div style="margin:0px auto;width:90%">

<p>' . trim(get_comment($parent_id)->comment_author) . ', 您好!</p>

<p>' . trim($comment->comment_author) . ' 于' . trim($comment->comment_date) . ' 给您的回复如下: </p>

$from = "From: \"" . get_option('blogname') . "\" <$wp_email>";

$headers = "$from\nContent-Type: text/html; charset=" . get_option('blog_charset') . "\n";

wp_mail( $to, $subject, $message, $headers );

//echo 'mail to ', $to, '<br/> ' , $subject, $message; // for testing

}

}

add_action('comment_post', 'comment_mail_notify');
