SMTP邮件功能是WordPress中很常用的功能, 虽然WordPress自带了mail函数,但用自带mail函数发送邮件很容易失败或者被拒收。有很多虚拟主机基本都是禁用了 mail 函数,所以我们只能使用SMTP服务发送邮件,网上关于SMTP的WordPress插件有很多,今天我分享一种纯代码实现WordPress评论回复自动邮件提醒。

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\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;
