WordPress phpmailer 自定义插件

Question

我已经从 html/php 网站更改为当地居民协会的 wordpress cms 网站，除了电子邮件位之外，一切都很好。 我对 WordPress 的唯一体验是过去几个月我玩得很开心的自定义构建，我没有真正理解 WordPress 与 phpmailer 的反应，除了一个版本被包装在 wp_mail 中，这是我试图避免的，希望能够去直接到我的服务器。 我有一个现有的 phpmailer smtp 脚本，在旧站点上运行得很好，我尝试了各种方法在 WordPress 上实现此功能，但没有成功，我发现如果我将其设为插件，那么很多问题就会消失，例如格式化页面等，在我看来这很重要。 有人可以帮助我或向我解释为什么这不起作用以及我必须做什么才能让这个脚本工作。

Answer 1

我建议不要包含您自己的 PHPMailer 副本，因为当 WordPress 中的内容更新时，它不太可能被更新。

您可以通过编写一个函数来获取 WordPress 的 PHPMailer 实例，然后将该函数链接到 WordPress 的 phpmailer_init 挂钩：

add_action('phpmailer_init', 'mailer_config');
function mailer_config(PHPMailer $mailer){
  $mailer->isSMTP();
  $mailer->Host = "mail.example.com"; // your SMTP server
  $mailer->Port = 25;
  $mailer->SMTPDebug = 2;
  $mailer->CharSet  = "utf-8";
  //etc
}

设置完毕后，当您调用 wp_mail( ）。

另外，要创建模板，您会发现使用 PHP 的 heredoc 语法 比所有这些连接操作。
