创建电子邮件功能以使用各种模板发送邮件时出错

Question

我正在尝试创建一个 php 类来使用各种模板发送邮件。例如，我想发送带有用户名和密码的欢迎邮件。我正在尝试创建一个名为 sendwelcomemail() 的电子邮件函数，它正在从 getmailautho() 类访问默认的 php 邮件配置。

代码如下：

<?php
// Include the PHPMailer class
include('PHPMailer/class.phpmailer.php');
require_once 'PHPMailer/PHPMailerAutoload.php';

class email {


public function getmailauth(){

    // Setup PHPMailer
$mail = new PHPMailer();
$mail->IsSMTP();

// This is the SMTP mail server
$mail->Host = 'smtp.gmail.com';

// Remove these next 3 lines if you dont need SMTP authentication
$mail->Port = 587;
$mail->SMTPAuth = true;
$mail->Username = 'test@gmail.com';
$mail->Password = 'testing';
$mail->SMTPOptions = array(
    'ssl' => array(
        'verify_peer' => false,
        'verify_peer_name' => false,
        'allow_self_signed' => true
    )
);

// Set who the email is coming from
$mail->SetFrom('testing@gmail.com', 'test');


}

function sendwelcomemail($username,$password,$to){
    $this->getmailauth();
    global $mail;
    // Retrieve the email template required
$message = file_get_contents('templates/welcome.html');

// Replace the % with the actual information
$message = str_replace('%username%', $username, $message);
$message = str_replace('%password%', $password, $message);


// Set who the email is sending to
$mail->AddAddress($to);

// Set the subject
$mail->Subject = 'Your account information';

//Set the message
$mail->MsgHTML($message);
$mail->AltBody = strip_tags($message);

// Send the email
if(!$mail->Send()) {
 echo "Mailer Error: " . $mail->ErrorInfo;
}

}
}
?>


<h3> testing </h3>
<?php
$email = new email;
$email->sendwelcomemail("test","test","test@test.com");

?>

当我运行这个脚本时，我收到以下错误：

致命错误：第 49 行 C:\xampp\htdocs\db\mail_function.php 中的 null 时调用成员函数 AddAddress()

你们能帮我解决这个错误吗？也欢迎任何建议:)

在__constructor() 中定义您的邮件对象或在函数外部定义它（以使其他函数可以访问 PHPMailer 对象）并从sendwelcomemail() 中删除全局 $mail

<?php
// Include the PHPMailer class
include('PHPMailer/class.phpmailer.php');
require_once 'PHPMailer/PHPMailerAutoload.php';

class email {
    private $mail;
function __constructor(){
// Setup PHPMailer
$this->$mail = new PHPMailer();
}

public function getmailauth(){

$this->$mail->IsSMTP();

// This is the SMTP mail server
$this->$mail->Host = 'smtp.gmail.com';

// Remove these next 3 lines if you dont need SMTP authentication
$this->$mail->Port = 587;
$this->$mail->SMTPAuth = true;
$this->$mail->Username = 'test@gmail.com';
$this->$mail->Password = 'testing';
$this->$mail->SMTPOptions = array(
    'ssl' => array(
        'verify_peer' => false,
        'verify_peer_name' => false,
        'allow_self_signed' => true
    )
);

// Set who the email is coming from
$this->$mail->SetFrom('testing@gmail.com', 'test');


}

function sendwelcomemail($username,$password,$to){
    $this->getmailauth();
    // Retrieve the email template required
$message = file_get_contents('templates/welcome.html');

// Replace the % with the actual information
$message = str_replace('%username%', $username, $message);
$message = str_replace('%password%', $password, $message);


// Set who the email is sending to
$this->$mail->AddAddress($to);

// Set the subject
$this->$mail->Subject = 'Your account information';

//Set the message
$this->$mail->MsgHTML($message);
$this->$mail->AltBody = strip_tags($message);

// Send the email
if(!$this->$mail->Send()) {
 echo "Mailer Error: " . $this->$mail->ErrorInfo;
}

}
}
?>
