Question

我想在我的简报中添加一个linf来取消签名。我无法在通讯中提供变量“email”。我同时将电子报发送给某个电子邮件 $ template允许时事通讯从数据库获取数据，我的时事通讯在html中使用如下变量：{{variable}} 我试着把我的代码模板放进去，但电子邮件仍然是第一封电子邮件。你有什么想法吗？

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');

}

您只从文件中提取$template一次，但之后您尝试多次替换它。在第一次更换后，它将使用第一个收件人的数据进行修复。

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');
}

作为改进，您可以只运行一次替换（在foreach循环之前替换不会更改的内容（例如$_POST['newsletter_top']），然后单独替换$newsletter_unsign内的foreach {{1}}循环，但我将把它作为OP的练习。
