Question

让我看看我能解释我想要做的最好的代码示例。我只是在清理我的代码，想要找出最好的方法来解决问题。我有一个表单，当我点击提交它发送给我和电子邮件工作正常（使用phpmailer，使用作曲家安装）

以下工作代码：这是我在提交后调用的帖子，工作正常。我想将php邮件代码移动到我创建的单独命名空间中。

    $app->post('/', function ($request, $response) {

  $mail = new PHPMailer;                             // Enable verbose debug output

  $mail->isSMTP();                                      // Set mailer to use SMTP
  $mail->Host = 'smtp.stackmail.com';  // Specify main and backup SMTP servers
  $mail->SMTPAuth = true;                               // Enable SMTP authentication
  $mail->Username = 'info@nicolauslawson.com';                 // SMTP username
  $mail->Password = 'miya1234';                           // SMTP password
  $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
  $mail->Port = 587;                                    // TCP port to connect to

  $mail->setFrom('info@nicolauslawson.com', 'Mailer');
  $mail->addAddress('nicolaus.lawson@gmail.com', 'Joe User');     // Add a recipient

  $mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
  $mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
  $mail->isHTML(true);                                  // Set email format to HTML

  $mail->Subject = 'Here is the subject';
  $mail->Body    = '    <div class="container">
        <p>Name: '.$request->getParam('name').'</p>
        <p>Number: '.$request->getParam('number').'</p>
        <p>Dept: '.$request->getParam('dept').'</p>
        <p>Date of last leave: '.$request->getParam('singedate1').'</p>
        <p>Date of last resume: '.$request->getParam('singedate2').'</p>
        <p>Date Request: '.$request->getParam('datefilter').'</p>
      </div>';
  $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

  if(!$mail->send()) {
      echo 'Message could not be sent.';
      echo 'Mailer Error: ' . $mail->ErrorInfo;
  } else {
      echo 'Message has been sent';
  }
});

使用psr-4

创建下面的命名空间

    "autoload": {
  "psr-4": {
    "App\\": "app"
  }

然后我将代码移动到名为Mailer.php的文件

    <?php

namespace App\Controllers;

class Mailer
{
  public function sendMail()
  {
    $mail = new PHPMailer;

    //$mail->SMTPDebug = 3;                               // Enable verbose debug output

    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'smtp.stackmail.com';  // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = 'info@nicolauslawson.com';                 // SMTP username
    $mail->Password = 'miya1234';                           // SMTP password
    $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 587;                                    // TCP port to connect to

    $mail->setFrom('info@nicolauslawson.com', 'Mailer');
    $mail->addAddress('nicolaus.lawson@gmail.com', 'Joe User');     // Add a recipient

    $mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
    $mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
    $mail->isHTML(true);                                  // Set email format to HTML

    $mail->Subject = 'Here is the subject';
    $mail->Body    = '    <div class="container">
          <p>Name: '.$request->getParam('name').'</p>
          <p>Number: '.$request->getParam('number').'</p>
          <p>Dept: '.$request->getParam('dept').'</p>
          <p>Date of last leave: '.$request->getParam('lastleave').'</p>
          <p>Date of last resume: '.$request->getParam('lastresume').'</p>
          <p>Date: '.$request->getParam('datefilter').'</p>
        </div>';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    if(!$mail->send()) {
        echo 'Message could not be sent.';
        echo 'Mailer Error: ' . $mail->ErrorInfo;
    } else {
        echo 'Message has been sent';
    }
  }
}

最后在我的路线中我有

$app->post('/', '\App\Controllers\Mailer:sendMail');

只是想弄清楚我哪里出错了以及为什么在移动代码后，当我从Mailer.php调用该函数时它不起作用我知道我得到了psr-4和命名空间工作，因为当我删除所有的代码并放在下面：

   <?php

namespace App\Controllers;

class Mailer
{
  public function sendMail()
  {
    return 'Working';
  }
}

工作正常。有什么建议？对不起这么长的问题人

Answer 1

这是因为您尝试调用类PHPMailer，并且您的应用程序将尝试在App\Controllers\PHPMailer中找到它。

您需要import the namespace或添加global fallback，然后才能正常使用。

导入命名空间：

namespace App\Controllers;

use PHPMailer; // Import PHPMailer from global PHPMailer

class Mailer
{
    public function sendMail()
    {
        $mail = new PHPMailer;

回归全球：

<?php

namespace App\Controllers;

class Mailer
{
    public function sendMail()
    {
        // The leading \ tells PHP that the class is in the global namespace and not within this namespace
        $mail = new \PHPMailer;

使用phpmailer调用路由中的函数
