取消订阅时事通讯

Question

我想添加一个 linf 来取消签署我的时事通讯。我无法成功在时事通讯中提供我的变量“电子邮件”。 我同时将简讯发送到某个电子邮件地址 $template 允许新闻通讯从数据库获取数据，我的新闻通讯在 html 中，变量如下：{{variable}} 我尝试将我的代码模板放在我的 while 中，但电子邮件仍然是第一个 emai。 你有主意吗？

这是代码：

if($_POST['recipients']) {

    $template = file_get_contents('template/emails/newsletter.html');

    $addresses = explode(';', $_POST['recipients']);
    $subject = stripslashes($_POST['subject']);
    foreach($addresses as $address) {

    $newsletter_unsign =  ' <a href="http://dev.cater2.me/unsign-newsletter.php?id='.$address.'">Unsubscribe from the newsletter</a>.';

    $template = str_replace(array('{{newsletter_top_bar}}','{{newsletter_top}}','{{newsletter_title1}}','{{newsletter_body1}}','{{newsletter_title2}}','{{newsletter_body2}}','{{newsletter_title3}}','{{newsletter_body3}}','{{newsletter_side_title}}','{{newsletter_side}}','{{newsletter_bottom}}','{{newsletter_footer}}','{{newsletter_unsign}}'),
                  array($_POST['newsletter_top_bar'],$_POST['newsletter_top'],$_POST['newsletter_title1'],$_POST['newsletter_body1'],$_POST['newsletter_title2'],$_POST['newsletter_body2'],$_POST['newsletter_title3'],$_POST['newsletter_body3'],$_POST['newsletter_side_title'],$_POST['newsletter_side'],$_POST['newsletter_bottom'],$_POST['newsletter_footer'], $newsletter_unsign),
                  $template);


        $address = trim($address);

        sendMail($address, $subject, str_replace('{{c2me_tracking_link}}', 'http://cater2.me/?ref='.urlencode(c2me_encrypt($address)), $template), true);
    }

    notif('E-mail(s) sent');
}

}

if($_POST['recipients']) {

    $original_template = file_get_contents('template/emails/newsletter.html');

    $addresses = explode(';', $_POST['recipients']);
    $subject = stripslashes($_POST['subject']);

    foreach($addresses as $address) {

      // You should have made sure before/outside the foreach loop, that the e-mails are well-formatted and valid
      $address = trim($address);

      $this_template = $original_template;

      $newsletter_unsign =  ' <a href="http://dev.cater2.me/unsign-newsletter.php?id='.$address.'">Unsubscribe from the newsletter</a>.';

      $this_template = str_replace(array('{{newsletter_top_bar}}','{{newsletter_top}}','{{newsletter_title1}}','{{newsletter_body1}}','{{newsletter_title2}}','{{newsletter_body2}}','{{newsletter_title3}}','{{newsletter_body3}}','{{newsletter_side_title}}','{{newsletter_side}}','{{newsletter_bottom}}','{{newsletter_footer}}','{{newsletter_unsign}}'),
                  array($_POST['newsletter_top_bar'],$_POST['newsletter_top'],$_POST['newsletter_title1'],$_POST['newsletter_body1'],$_POST['newsletter_title2'],$_POST['newsletter_body2'],$_POST['newsletter_title3'],$_POST['newsletter_body3'],$_POST['newsletter_side_title'],$_POST['newsletter_side'],$_POST['newsletter_bottom'],$_POST['newsletter_footer'], $newsletter_unsign),
                  $this_template);

      sendMail($address, $subject, str_replace('{{c2me_tracking_link}}', 'http://cater2.me/?ref='.urlencode(c2me_encrypt($address)), $this_template), true);
    }
    notif('E-mail(s) sent');

}

您仅从文件中获取 $template 一次，但随后尝试多次替换它。第一次替换后，它会被固定为第一个收件人的数据。

尝试将替换的字符串分配给新变量，例如 $template_after_replace：

if($_POST['recipients']) {

  $template = file_get_contents('template/emails/newsletter.html');

  $addresses = explode(';', $_POST['recipients']);
  $subject = stripslashes($_POST['subject']);
  foreach($addresses as $address) {

    $newsletter_unsign =  ' <a href="http://dev.cater2.me/unsign-newsletter.php?id='.$address.'">Unsubscribe from the newsletter</a>.';

    $template_after_replace = str_replace(array('{{newsletter_top_bar}}','{{newsletter_top}}','{{newsletter_title1}}','{{newsletter_body1}}','{{newsletter_title2}}','{{newsletter_body2}}','{{newsletter_title3}}','{{newsletter_body3}}','{{newsletter_side_title}}','{{newsletter_side}}','{{newsletter_bottom}}','{{newsletter_footer}}','{{newsletter_unsign}}'),
              array($_POST['newsletter_top_bar'],$_POST['newsletter_top'],$_POST['newsletter_title1'],$_POST['newsletter_body1'],$_POST['newsletter_title2'],$_POST['newsletter_body2'],$_POST['newsletter_title3'],$_POST['newsletter_body3'],$_POST['newsletter_side_title'],$_POST['newsletter_side'],$_POST['newsletter_bottom'],$_POST['newsletter_footer'], $newsletter_unsign),
              $template);


    $address = trim($address);

    sendMail($address, $subject, str_replace('{{c2me_tracking_link}}', 'http://cater2.me/?ref='.urlencode(c2me_encrypt($address)), $template_after_replace), true);
  }

  notif('E-mail(s) sent');
}

作为一项改进，您只需运行替换一次（在 foreach 循环之前替换那些不会出现的内容） t 更改（例如 $_POST['newsletter_top']），然后在 foreach 循环中单独替换 $newsletter_unsign，但我将其保留为OP 的练习。
