無法使用Swift Mailer發送電子郵件

Question

$transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, "ssl")

->setUsername('username')
->setPassword('password');

$username = $_SESSION['username'];  
$from = $_POST['from'];
$to =  $_POST['to'];
$subject = $_POST['subject'];
$body = $_POST['message'];

$message = Swift_Message::newInstance($subject)

->setFrom(array($from => $username))
->setTo(array($to))
->setBody($body);

$mailer = Swift_Mailer::newInstance($transport);
$result = $mailer->send($message);

在網絡瀏覽器上返回錯誤：

Answer 1

替換以下代碼：

$message = Swift_Message::newInstance('$subject')

->setFrom(array('$from' => '$username'))
->setTo(array('$to'))
->setBody('$body');

同

$message = Swift_Message::newInstance($subject)

->setFrom(array($from => $username))
->setTo(array($to))
->setBody($body);

如此處所示，您正在使用單引號，這是代碼中的問題。

Answer 2

取代這個

-> setUsername（'用戶名'）

-> setPassword（'password'）;

同

$ transport-> setUsername（'username'）; / *注意：用戶名是您的gmail用戶名（例如
asaa@gmail.com）* /

$ transport-> setPassword（'password'）; / password是您的Gmail密碼 /
