2019 无法调用不创建 PHPMailer 版本 6.0.7 实例的新 PHPMailer

Question

无法调用新的 PHPMailer，也没有创建 PHPMailer 的实例。 $mail->SMTPDebug 的设置创建了一个 stdClass 实例，然后对其调用不存在的方法 (isSMTP) 失败。所以这一切都归结为实例创建失败。 PHPMailer 版本 6.0.7 实时托管服务

我试过 $mail = new stdClass();
或者 $mail = NULL；这是症状修复，但不是原因，它会导致我的页面每次加载时都发送一封电子邮件。

 <?php 
    use PHPMailer\PHPMailer\PHPMailer;
    use PHPMailer\PHPMailer\Exception;
    require 'PHPMailer/Exception.php';
    require 'PHPMailer/PHPMailer.php';
    require 'PHPMailer/SMTP.php';


    if(isset($_POST[‘submit’]))

    $mail = new PHPMailer(true);

    $mail->SMTPDebug = 2; // 0 = off (for production use) - 1 = client messages - 2 = client and server messages
    $mail->isSMTP(); 

    $mail->Host = 'mail.email.org'; 
    $mail->SMTPSecure = 'ssl'; <-- Recommend by the hosting service 
    $mail->Port = 465; <-- Recommend by the hosting service <--Hosting Service Docs verify this
    $mail->SMTPAuth = true;
    $mail->Username = 'Mail@email.org';
    $mail->Password = 'Using the correct Password'; 


    $to = 'Mail@email.org'; <-- sending this to myself
    $from = 'Mail@email.org'; <--sending to myself


    $first_name = ((isset($_POST['FirstName']))&&(!is_null($_POST['FirstName'])))? $_POST['FirstName']:'';
    $last_name = ((isset($_POST['LastName']))&&(!is_null($_POST['LastName'])))? $_POST['LastName']:'';
    $email = ((isset($_POST['Email']))&&(!is_null($_POST['Email'])))? $_POST['Email']:'';
    $age = ((isset($_POST['Age']))&&(!is_null($_POST['Age'])))? $_POST['Age']:'';
    $student = ((isset($_POST['Student']))&&(!is_null($_POST['Student'])))? $_POST['Student']:'';
    $agree18 = ((isset($_POST['Agree18']))&&(!is_null($_POST['Agree18'])))? $_POST['Agree18']:'';


   /* Set the mail sender. */
    $mail->setFrom( $to , 'Research');

   /* Add a recipient. */
    $mail->addAddress( $_POST['Email'] , 'Research');
   /* Set the subject. */
    $mail->Subject = 'Learn More about Research Requested';

    $mail->isHTML(TRUE);
    $mail->Body = '<html> "First Name:" . $first_name . " Last Name:" . $last_name .  " Email:". $email . " Age:" . $age . " Student:" . $student . " Agree18:" . $agree18 . ""
</html>';


    $mail->AltBody = ' "First Name:" . $first_name . " Last Name:" . $last_name .  " Email:". $email . " Age:" . $age . " Student:" . $student . " Agree18:" . $agree18 . ""
';  

    if($mail->send()){

      $msg="Your email msg has been send";


    }else{

       $msg="mail msg has not been send"; 
       echo 'Mailer Error: ' . $mail->ErrorInfo;
     }
    ?>

希望找到失败原因的解决方案。

删除了我所有的代码，执行了同步说明的内容并得到了这个：

Answer 1

您忘记了 isset($_POST[...]) 条件后的括号。

if(isset($_POST['submit'])) {
    //                      ^^
    $mail = new PHPMailer(true);

    $mail->SMTPDebug = 2; // 0 = off (for production use) - 1 = client messages - 2 = client and server messages
    $mail->isSMTP(); 
    ...
}
// of course, don'f forget to add a closing one too here.

Answer 2

这是 your previous question 的副本，但标题不同。

当您有不起作用的代码时，将其缩减为最小的示例，以便您排除歧义的机会，并启用详细、可见的错误报告：

use PHPMailer\PHPMailer\PHPMailer;
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
require 'PHPMailer/PHPMailer.php';
$mail = new PHPMailer;
var_dump($mail);

如果这不起作用，则更复杂的脚本也不起作用。如果失败，我怀疑您的 PHP 安装存在严重错误，至少我希望看到一些警告记录。

已修复 <-- 感谢 Synchro --> & 感谢 Panthers 的输入

添加使用PHPMailer\PHPMailer\SMTP； <- 这解决了我的大部分问题，但并非每个 Synchro 都需要
