MVC PHPMailer流

Question

我想在我的MVC网站中使用PHPMailer ，但是$ emailTemplate变量的视图内容不存在。 这是我自己的MVC。 问题从这里开始： $emailTemplate = $this->view('emails/expirityRemainder'); 有人可以告诉我如何应对这种变化吗？

如果可以，一切正常，但是我需要加载不同的视图： $emailTemplate = 'The email body';

这是我的控制器：

<?php
class Emails extends Controller{

    //Send email to remamber the expirity date
    public function sendReinder($data){ 
        $emailTemplate = $this->view('emails/expirityRemainder');
        $data=[
            'recipient'=>'anEmail@yahoo.com',
            'subject'=>'TheSubject',
            'htmlBody'=>$emailTemplate,
            'nonHtmlBody'=>'This is the body in plain text for non-HTML mail clients',
            'sentMessage'=>'Message has been sent'
        ];
        $email = new Email();
        $email->sendMail($data);
    }
}

“ expirityRemainder.php”文件包含一个文本： Here will be the HTML code formatted

PHPMailer文件在该library / PHPMailer文件夹内。 Email类发送电子邮件（在我的服务器上，以下空白详细信息已填写）：

<?php
// Import PHPMailer classes into the global namespace
// These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'src/Exception.php';
require 'src/PHPMailer.php';
require 'src/SMTP.php';
class Email{
    public function sendMail($data){


        $mail = new PHPMailer(true);                              // Passing `true` enables exceptions
        try {
        //Server settings
        $mail->SMTPDebug = 0;                                 // Enable verbose debug output
        $mail->isSMTP();                                      // Set mailer to use SMTP
        $mail->Host = '';  // Specify main and backup SMTP servers smtp.topwebdeveloper.co.uk
        $mail->SMTPAuth = true;                               // Enable SMTP authentication
        $mail->Username = '';                 // SMTP username
        $mail->Password = '';                           // SMTP password
        $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
        $mail->Port = 587;                                     // TCP port to connect to 465 25 587

        //Recipients
        $mail->setFrom('', '');
        //$mail->addAddress('', '');     // Add a recipient
        //$mail->addAddress('');               // Name is optional
        $mail->addAddress($data['recipient'], 'Nameee');
        $mail->addReplyTo('', 'Information');


        //Content
        $mail->isHTML(true);                                  // Set email format to HTML
        $mail->Subject = 'Here is the subject';
        $mail->Body    = $data['htmlBody'];
        $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

        $mail->send();
        echo 'Message has been sent';
        print_r($data);
        } catch (Exception $e) {
            echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
            print_r($data);
        }

    }
}

?>

这是输出：

Here will be the html code formatted
Message could not be sent. 
Mailer Error: Message body emptyArray ( [recipient] => anEmail@yahoo.com [subject] => TheSubject [htmlBody] => [nonHtmlBody] => This is the body in plain text for non-HTML mail clients [sentMessage] => Message has been sent )`

我认为视图内容应该不是字符串...如果sendMail（$ data）没有收到视图内容，则$data['htmlBody']里面的内容。

view方法非常适合我的MVC，但在尝试加载邮件文本的情况下除外：

<?php
        class Controller{
            public function model($model){
                require_once '../app/models/'.$model.'.php';
                return new $model();
            }

            public function view($view, $data=[]){
                if(file_exists('../app/views/'.$view.'.php')){
                    require_once '../app/views/'.$view.'.php';
                } else {
                    die('vien not exists');
                }
            }
        }

我创建了一个新方法，但仍然无法正常工作：

<?php
    public function loadEmailView($view, $data=[]){
        if(file_exists('../app/views/'.$view.'.php')){

            //ob_start();
            //include('../app/views/'.$view.'.php');
            //$file = ob_end_flush();

            //echo file_get_contents('../app/views/'.$view.'.php');

            //$data['htmlBody'] = require_once '../app/views/'.$view.'.php';

        } else {
            die('Email vien not exists');
        }
    }

上述3个解决方案均未将视图内容添加到我的htmlBody变量中：

<?php
class Emails extends Controller{

    //Send email to remamber the expirity date
    public function sendReinder($data){ 
        $emailTemplate = $this->loadEmailView('emails/expirityRemainder');
        //$emailTemplate = file_get_contents('email_template.php');
        $data=[
            'recipient'=>'anEmail@yahoo.com',
            'subject'=>'TheSubject',
            'htmlBody'=>$emailTemplate,
            'nonHtmlBody'=>'This is the body in plain text for non-HTML mail clients',
            'sentMessage'=>'Message has been sent'
        ];
        $email = new Email();
        $email->sendMail($data);
    }
}

谢谢！
