WordPress默认主题中用户留言评论,如果我们去回复之后,或者我们用户评论的时候也不会自动通知博主的。我们可以添加评论邮件通知,这样可以及时的与用户进行互动。当然,有很多插件可以实现这样的功能,在这篇文章中,国外主机优惠收集到的办法是不用插件,直接在当前主题Functions.php文件中加入代码就可以实现。
第一、自动默认全部通知
// 评论回应邮件通知
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\”) . \’] 的留言有了回应\’;
$message = \’
<div style=\”background-color:#eef2fa; border:1px solid #d8e3e8; color:#111; padding:0 15px; -moz-border-radius:5px; -webkit-border-radius:5px; -khtml-border-radius:5px;\”>
<p>\’ . trim(get_comment($parent_id)->comment_author) . \’, 您好!</p>
<p>您曾在《\’ . get_the_title($comment->comment_post_ID) . \’》的留言:<br />\’

<p>\’ . trim($comment->comment_author) . \’ 给您的回应:<br />\’
. trim($comment->comment_content) . \'<br /></p>
<p>您可以点击 <a href=\”\’ . htmlspecialchars(get_comment_link($parent_id)) . \’\”>查看回应完整內容</a></p>
<p>欢迎您再度光临 <a href=\”\’ . get_option(\’home\’) . \’\”>\’ . get_option(\’blogname\’) . \'</a></p>
<p>(此邮件由系统自动发出,请勿回复.)</p>
</div>\’;
$from = \”From: \\\”\” . get_option(\’blogname\’) . \”\\\” <$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, $message; // for testing
}
}
add_action(\’comment_post\’, \’comment_mail_notify\’);
// 自动勾选
function add_checkbox() {
echo \'<input type=\”checkbox\” name=\”comment_mail_notify\” id=\”comment_mail_notify\” value=\”comment_mail_notify\” checked=\”checked\” style=\”margin-left:0px;\” /><label for=\”comment_mail_notify\”>有人回复时邮件通知我</label>\’;
}
add_action(\’comment_form\’, \’add_checkbox\’);
第二、用户可选通知
/* 用户选择是否通知*/
function comment_mail_notify($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>\”;
$headers = \”$from\\nContent-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\’);
需要注意的是,我们需要将当前服务器环境支持MAIL函数才可以实现邮件推送。
