wordpress无插件实现六个经典功能

wordpress建站系统为我们提供了丰富的插件功能,但是使用太多的插件往往会拖慢网站的速度,其实一些小插件的功能我们完全可以自己用代码实现,下面是我为大家整理的一些wordpress经典功能的无插件纯代码实现方法,代码来自互联网。如果没有特殊说明,下面的代码请放在主题文件夹(…/wp-content/themes/你的主题/)的模板函数functions.php文件里,修改方法:将下面代码复制粘贴到functions.php的<?php……..?>局域内。

wordpress无插件实现六个经典功能

修改wordpress代码实现smtp邮件功能

相关插件:easy wp smtp 下载地址((经本人汉化))[button class=”download” size=”lg” href=”http://pan.baidu.com/s/1mgqV5Rq" title=”easy wp smtp”]密码:0bmd [/button]

//使用smtp发邮件
add_action(‘phpmailer_init’, ‘mail_smtp’);
function mail_smtp( $phpmailer ) {
$phpmailer->IsSMTP();
$phpmailer->SMTPAuth = true;//启用SMTPAuth服务
$phpmailer->Port = 465;//MTP邮件发送端口,这个和下面的对应,如果这里填写25,则下面为空白
$phpmailer->SMTPSecure =”ssl”;//是否验证 ssl,这个和上面的对应,如果不填写,则上面的端口须为25
$phpmailer->Host =”smtp.gmail.com”;//邮箱的SMTP服务器地址,如果是QQ的则为:smtp.exmail.qq.com
$phpmailer->Username = “admin@gmail.com“;//你的邮箱地址
$phpmailer->Password =”**“;//你的邮箱登陆密码
}

WordPress无插件代码实现评论回复邮件通知

//comment_mail_notify(所有的回复都会发邮件通知)

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”).’]的留言有了回复’;
$message = ‘

‘.trim(get_comment($parent_id)->comment_author).’, 您好!

这是您在《’.get_the_title($comment->comment_post_ID).’》中的留言:

.trim(get_comment($parent_id)->comment_content).’

以下是’.trim($comment->comment_author).’ 给您的回复:

.trim($comment->comment_content).’

您可以点击这里查看回复的完整内容.

欢迎再度光临 ‘ . get_option(‘blogname’) . ‘

(注:此邮件由系统自动发出,请勿回复!)


‘;
$from = “From: “” . get_option(‘blogname’) . “” <$wp_email>”;
$headers = “$fromnContent-Type: text/html; charset=” . get_option(‘blog_charset’) . “n”;
wp_mail( $to, $subject, $message, $headers );
//echo ‘mail to ‘, $to, ‘
‘ , $subject, $message; // for testing
}
}
