Swiftmailer：发送电子邮件给多个收件人 [英] Swiftmailer: sending email to multiple recipient

问题描述

我试图通过swiftmailer lib从联系人表单发送电子邮件。我的设置将邮件发送给单个收件人，但是当我尝试发送给多个电子邮件时，它会引发错误：

邮箱中的地址因为[email1 @ gmail.com，email2 @ gmail.com]不符合RFC 2822,3.6.2。

<但是这两封电子邮件根据规范是有效的。

这是代码;

  $ failed = []; 
 $ sent = 0; 
 $ to = []; 
 
 if（isset（$ _ POST ['recipients']））{
 $ recipients = $ _POST ['recipients']; 
 
 
发送消息
 foreach（（array）$ recipients as $ to）{
 $ message-> setTo（$ to）; 
 $ sent + = $ mailer-> send（$ message，$ failed）; 
} 
 
 print_r（$ recipients）; 
 printf（发送％d个消息\\\
，$发送）; 
  

当我在输入字段中发送一封电子邮件时， print_r（$ recipients ）给了我这个数组：（Array（[0] => [e-mail]）发送1条消息）之前，但现在不是给阵列。

我知道 foreach 需要数组，但是我没有得到一个数组。
$ b

有一次，我收到一个错误，收件人是未定义的;这就是为什么我添加了if isset（） check。

如何分别发送每封电子邮件

解决方案

它看起来像 $ _ POST ['recipients'] 是一个逗号分隔字符串。您需要使用 explode（） 来分割逗号上的字符串。将它转换为数组不会为你做：

  //我们应该给$收件人一个默认值，以防万一它是空的。 
 //否则，当你在foreach循环中使用它的时候你会得到一个错误
 $ recipients = []; 
 
 if（！empty（$ _ POST ['recipients']））{
 //爆炸字符串
 $ recipients = explode（'，'，$ _POST ['recipients ]）; 
} 
 
 //发送消息
 foreach（$ recipients as $ to）{
 //为了安全起见，我们也应该修剪地址，任何潜在的空间。 
 $ message  - > setTo（trim（$ to））; 
 $ sent + = $ mailer-> send（$ message，$ failed）; 
} 
  

I am trying to send email from a contact form through swiftmailer lib. My setup sends mail to a single recipient, but when I try sending to more than one email, it throws an error:

Address in mailbox given [[e-mail],[e-mail]] does not comply with RFC 2822, 3.6.2.

but the two emails are valid according to the specification.

Here is the code;

$failed = [];
$sent = 0;
$to = [];

if (isset($_POST['recipients'])) {
    $recipients = $_POST['recipients'];
}

// Send the message
foreach ((array) $recipients as $to) {
    $message->setTo($to);
    $sent += $mailer->send($message, $failed);
}

print_r($recipients);   
printf("Sent %d messages\n", $sent);

When I sent with one email in the input field, print_r($recipients) gave me this array: (Array ( [0] => [e-mail] ) Sent 1 messages) before but now it's not giving the array.

I learnt that foreach expects array, but I'm not getting an array.

At one point, I was getting an error that 'recipients' is undefined; that is why I added the if isset() check.

How do I send the each email individually?

解决方案

It looks like $_POST['recipients'] is a comma separated string. You need to use explode() to split the string on the commas. Casting it as an array won't do that for you:

// We should give $recipients a default value, in case it's empty.
// Otherwise, you would get an error when trying to use it in your foreach-loop
$recipients = [];

if(!empty($_POST['recipients'])){
    // Explode the string
    $recipients =  explode(',', $_POST['recipients']);
}      

// Send the message
foreach ($recipients as $to) {
    // To be safe, we should trim the addresses as well, removing any potential spaces. 
    $message ->setTo(trim($to));
    $sent += $mailer->send($message, $failed);
}
