取消訂閱電子報

Question

我想添加一個linf以便取消我的通訊。我無法在通訊中給出我的變量「email」。 我在同一時間發送電子郵件到一些電子郵件 $ template允許通訊從數據庫中獲取數據，我的通訊在HTML中的變量是這樣的：{{variable}} 我試圖把我的代碼模板放入我的一段時間，但電子郵件仍然是第一個電子郵件。 你有想法嗎？

下面的代碼：

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'); 

}

您只能從文件讀取$template一次，但你嘗試多次更換。第一次替換後，它與第一個收件人的數據一起修復。

嘗試將替換的字符串分配給新變量，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'); 
} 

作爲改進，你可以只運行一次更換（前foreach循環更換的東西，會不會改變（例如$_POST['newsletter_top']），然後逐個更換foreach環路內$newsletter_unsign，但我會把它作爲OP的練習。
