取消订阅电子报

Question

我想添加一个linf以便取消我的通讯。我无法在通讯中给出我的变量“email”。 我在同一时间发送电子邮件到一些电子邮件 $ template允许通讯从数据库中获取数据，我的通讯在HTML中的变量是这样的：{{variable}} 我试图把我的代码模板放入我的一段时间，但电子邮件仍然是第一个电子邮件。 你有想法吗？

下面的代码：

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'); 

}

您只能从文件读取$template一次，但你尝试多次更换。第一次替换后，它与第一个收件人的数据一起修复。

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，你可以只运行一次更换（前foreach循环更换的东西，会不会改变（例如$_POST['newsletter_top']），然后逐个更换foreach环路内$newsletter_unsign，但我会把它作为OP的练习。
