如何让WordPress实现评论回复邮件提醒的功能？
根据自己的需要选择，将下面的代码添加到当前主题的functions.php文件中即可：
方法一：所有回复都发送邮件通知
默认所有填写了邮箱的评论都将发邮件提醒评论人，没有任何勾选设置。
/* comment_mail_notify v1.0 by willin kan. (所有回复都发邮件) */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'])); //e-mail 发出点, no-reply 可改为可用的 e-mail. $to = trim(get_comment($parent_id)->comment_author_email); $subject = '您在 [' . get_option("blogname") . '] 的留言有了回复'; $message = ' <div style="background-color:#eef2fa; border:1px solid #d8e3e8; color:#111; padding:0 15px; -moz-border-radius:5px; -webkit-border-radius:5px; -khtml-border-radius:5px;"> <p>' . trim(get_comment($parent_id)->comment_author) . ', 您好!</p> <p>您曾在《' . get_the_title($comment->comment_post_ID) . '》的留言:<br />' . trim(get_comment($parent_id)->comment_content) . '</p> <p>' . trim($comment->comment_author) . ' 给您的回复:<br />' . trim($comment->comment_content) . '<br /></p> <p>您可以点击 查看回复完整內容</p> <p>欢迎再度光临 ' . get_option('blogname') . '</p> <p>(此邮件由系统自动发送，请勿回复.)</p> </div>'; $from = "From: "" . get_option('blogname') . "" <$wp_email>"; $headers = "$fromnContent-Type: text/html; charset=" . get_option('blog_charset') . "n"; wp_mail( $to, $subject, $message, $headers ); }}add_action('comment_post', 'comment_mail_notify');方法二：让访客自己选择是否邮件通知
在评论框下方显示一个勾选框，让评论人自己决定是否接收邮件通知。
function comment_mail_notify($comment_id) { $admin_notify = '1'; // admin 要不要收回复通知 ( '1'=要 ; '0'=不要 ) $admin_email = get_bloginfo ('admin_email'); // $admin_email 可改为你指定的 e-mail. $comment = get_comment($comment_id); $comment_author_email = trim($comment->comment_author_email); $parent_id = $comment->comment_parent ? $comment->comment_parent : ''; global $wpdb; if ($wpdb->query("Describe {$wpdb->comments} comment_mail_notify") == '') $wpdb->query("ALTER TABLE {$wpdb->comments} ADD COLUMN comment_mail_notify TINYINT NOT NULL DEFAULT 0;"); if (($comment_author_email != $admin_email && isset($_POST['comment_mail_notify'])) || ($comment_author_email == $admin_email && $admin_notify == '1')) $wpdb->query("UPDATE {$wpdb->comments} SET comment_mail_notify='1' WHERE comment_ID='$comment_id'"); $notify = $parent_id ? get_comment($parent_id)->comment_mail_notify : '0'; $spam_confirmed = $comment->comment_approved; if ($parent_id != '' && $spam_confirmed != 'spam' && $notify == '1') { $wp_email = 'no-reply@' . preg_replace('#^www.#', '', strtolower($_SERVER['SERVER_NAME'])); // e-mail 发出点, no-reply 可改为可用的 e-mail. $to = trim(get_comment($parent_id)->comment_author_email); $subject = '您在 [' . get_option("blogname") . '] 的留言有了回复'; $message = ' <div style="background-color:#eef2fa; border:1px solid #d8e3e8; color:#111; padding:0 15px; -moz-border-radius:5px; -webkit-border-radius:5px; -khtml-border-radius:5px;"> <p>' . trim(get_comment($parent_id)->comment_author) . ', 您好!</p> <p>您曾在《' . get_the_title($comment->comment_post_ID) . '》的留言:<br />' . trim(get_comment($parent_id)->comment_content) . '</p> <p>' . trim($comment->comment_author) . ' 给您的回复:<br />' . trim($comment->comment_content) . '<br /></p> <p>您可以点击查看回复的完整內容</p> <p>还要再度光临 ' . get_option('blogname') . '</p> <p>(此邮件由系统自动发送，请勿回复.)</p> </div>'; $from = "From: "" . get_option('blogname') . "" <$wp_email>"; $headers = "$fromnContent-Type: text/html; charset=" . get_option('blog_charset') . "n"; wp_mail( $to, $subject, $message, $headers ); }}add_action('comment_post', 'comment_mail_notify');/* 自动加勾选栏 */function add_checkbox() { echo '<input type="checkbox" name="comment_mail_notify" id="comment_mail_notify" value="comment_mail_notify" checked="checked" style="margin-left:20px;" /><label for="comment_mail_notify">有人回复时邮件通知我</label>';}add_action('comment_form', 'add_checkbox');方法三：让博客管理员决定什么情况下发邮件
调整下面的代码，选择发送回复邮件
/* comment_mail_notify v1.0 by willin kan. (无勾选栏) */function comment_mail_notify($comment_id) { $admin_email = get_bloginfo ('admin_email'); // $admin_email 可改为你指定的 e-mail. $comment = get_comment($comment_id); $comment_author_email = trim($comment->comment_author_email); $parent_id = $comment->comment_parent ? $comment->comment_parent : ''; $to = $parent_id ? trim(get_comment($parent_id)->comment_author_email) : ''; $spam_confirmed = $comment->comment_approved; if (($parent_id != '') && ($spam_confirmed != 'spam') && ($to != $admin_email) && ($comment_author_email == $admin_email)) { /* 上面的判断式,决定发出邮件的必要条件: ($parent_id != '') && ($spam_confirmed != 'spam'): 回复的, 而且不是 spam 才可发, 必需!! ($to != $admin_email) : 不发给 admin. ($comment_author_email == $admin_email) : 只有 admin 的回复才可发. 可视个人需修改上面的条件. */ $wp_email = 'no-reply@' . preg_replace('#^www.#', '', strtolower($_SERVER['SERVER_NAME'])); // e-mail 发出点, no-reply 可改为可用的 e-mail. $subject = '您在 [' . get_option("blogname") . '] 的留言有了回复'; $message = ' <div style="background-color:#eef2fa; border:1px solid #d8e3e8; color:#111; padding:0 15px; -moz-border-radius:5px; -webkit-border-radius:5px; -khtml-border-radius:5px;"> <p>' . trim(get_comment($parent_id)->comment_author) . ', 您好!</p> <p>您曾在《' . get_the_title($comment->comment_post_ID) . '》的留言:<br />' . trim(get_comment($parent_id)->comment_content) . '</p> <p>' . trim($comment->comment_author) . ' 给您的回复:<br />' . trim($comment->comment_content) . '<br /></p> <p>您可以点击 查看回复的完整內容</p> <p>还要再度光临 ' . get_option('blogname') . '</p> <p>(此邮件由系统自动发送，请勿回复.)</p> </div>'; $from = "From: "" . get_option('blogname') . "" <$wp_email>"; $headers = "$fromnContent-Type: text/html; charset=" . get_option('blog_charset') . "n"; wp_mail( $to, $subject, $message, $headers ); }}add_action('comment_post', 'comment_mail_notify');
