php - PHP 邮件程序和 Ajax

问题描述

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中。

这是代码

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


$mail->Send();

如果我先发送邮件，则邮件已发送，但未显示成功消息。

如果我把第一个 json_encode，消息显示但邮件不发送

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，但没有通过成功消息（虽然邮件正确到达）

如果有帮助，这是完整的代码

解决方案

您可能希望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，检查$mail->send()此操作是否返回 true，这意味着它失败了，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); 
}
