讓WordPress也能用電子郵件通知對方留言已回覆

好久好久以前，wordpress的留言似乎(我已經忘了)可以自動寄信通知管理者要審核，回覆留言也會寄信通知留言者你的留言有人回覆你了，現在新版的wordpress似乎已經沒有這個功能，所以我想把它加回來
先參考了網路的文章找到在2013年發表的外掛 Comment Reply by Admins Notifier，載點發現竟然還可以用勒~於是乎我又自己加工了一下，最後經過一連串的測試，證實是可以使用的。

原本的程式碼

<?php

exit();

}

add_action(‘comment_post’, ‘yh_comment_reply_by_admins_notifier’);

function yh_comment_reply_by_admins_notifier($comment_id)

{

$comment = get_comment($comment_id);

if( $comment->comment_parent != 0 )

{

if( current_user_can( ‘moderate_comments’ ) )

{

$current_user = wp_get_current_user();

if ( ($current_user->user_email == $comment->comment_author_email) )

{

$parent_comment = get_comment($comment->comment_parent);

if($parent_comment->user_id != $current_user->ID)

{

$email = $parent_comment->comment_author_email;

$adminname = $current_user->display_name;

$postlink = get_permalink($comment->comment_post_ID);

$commentlink = get_comment_link($comment_id);

$blogname = wp_specialchars_decode(get_option(‘blogname’), ENT_QUOTES);

$subject = sprintf(‘Your Comment was Replied – %1$s’, $blogname);

$notify_message = sprintf(‘%1$s (Admin of %2$s) replied to a comment you left on:’, $adminname, $blogname ) . ‘ ’;

$notify_message .= sprintf( ‘<a href=”%1$s”>%2$s</a>’, $postlink, $posttitle ) . “ ”;

$notify_message .= ‘You can check admin\’s comment here: ‘ . “ ”;

$notify_message .= ‘<a href=”‘ . $commentlink . ‘”>’ . $commentlink . ‘</a> ’;

$notify_message .= ‘This e-mail was sent by <a href=”‘ . get_home_url() . ‘”>’ . $blogname . ‘</a> ’;

$message_headers = “Content-Type: text/html; charset=\”” . get_option(‘blog_charset’) . “\”\n”;

wp_mail( $email, $subject, $notify_message, $message_headers );

}

}

}

}

}
