PHP 邮件程序和 Ajax

Question

我正在使用 Mail PHP 发送邮件。 我必须使用外部 SMTP，所以我添加了 PHP Mailer。

问题是成功的消息不会返回到表单。

这是代码

$output = json_encode(array('type'=>'message', 'text' => 'Ciao '.$user_Name .', grazie per averci contattato.'));
die($output);   


$mail->Send();

如果我把第一个邮件发送，邮件发送但不显示成功的消息。

如果我把第一个json_encode，显示消息但邮件不发送

我也试过这段代码

$output = json_encode(array('type'=>'message', 'text' => 'Ciao '.$user_Name .', grazie per averci contattato.'));
echo($output);   
return;

但它不起作用。

更新

我又试了一次，但成功消息没有通过（虽然邮件正确到达）

如果有帮助，这是完整的代码

您可能想在执行其他操作之前检查邮件是否已发送。因此，使用下面的代码，对$mail->send() 进行检查，如果此操作未返回 true，则意味着它失败了，我们可以做其他事情。否则，我们可以继续处理我们的 json。

if (!$mail->send()) {
    echo 'Mail Not send';
} else {
    $output = json_encode(array('type'=>'message', 'text' => 'Ciao '.$user_Name .', grazie per averci contattato.'));
    echo($output); 
}
