Question

我正在使用PHPMailer发送电子邮件。但我必须编写在每个页面上发送电子邮件的冗长代码。因此，我想尝试将所有内容放入一个函数中，并在我想使其变得干燥，简单和容易时随时调用它。但是在尝试发送电子邮件时它不起作用。我尝试了以下方法：

functions.php

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require 'phpmailer/src/Exception.php';
require 'phpmailer/src/PHPMailer.php';
require 'phpmailer/src/SMTP.php';

$settings = $pdo->prepare("SELECT * FROM settings");
$settings-> execute();
$set = $settings->fetch();

function newMail($name, $email, $sub, $msg, $set) {
  $mail = new PHPMailer;
  $mail->isSMTP();
  $mail->SMTPDebug = 0;
  $mail->Host = $set['set_smtp_host'];
  $mail->Port = $set['set_smtp_port'];
  $mail->SMTPSecure = $set['set_smtp_security'];
  $mail->IsHTML(true);
  $mail->SMTPAuth = true;
  $mail->Username = $set['set_smtp_uname'];
  $mail->Password = $set['set_smtp_pass'];
  $mail->setFrom($set['set_noreply_email'], $set['set_site_name']);
  $mail->addAddress($email, $name);
  $mail->Subject = $sub;
  $mail->Body    = $msg;
  $mail->Send();
}

现在，我尝试通过这种方式在另一页（其中包含functions.php）上调用该函数：

$fname = (!empty($_POST['fname']))?$_POST['fname']:null;
$email = (!empty($_POST['email']))?$_POST['email']:null;

$sub = ''.$title.' - Account Verification Link';
$msg = 'SOME BODY MESSAGE';

if(newMail($fname, $email, $sub, $msg)){
    echo alert_success("Registration successful! Please check your email and click on the activation link to activate your account. If you did not receive any email within 5 minutes then <a href='resend.php'>click here</a> to resend it.");
}else{
    echo alert_success("Registration successful! But unfortunately, we could not send you a verification email. Please <a href='resend.php'>click here</a> to resend it.");
}

这里总是返回else消息。我在这里编码错误吗？

最后，通过

修改功能 newMail ：

return   $mail->Send();

如果已发送邮件，则send方法返回true，因此您的函数应该返回该值，否则返回：

if(newMail(...)){ }

对于为什么要应用else情况，永远都是错误的。

function newMail($name, $email, $sub, $msg, $set) {
  $mail = new PHPMailer;
  $mail->isSMTP();
  $mail->SMTPDebug = 0;
  $mail->Host = $set['set_smtp_host'];
  $mail->Port = $set['set_smtp_port'];
  $mail->SMTPSecure = $set['set_smtp_security'];
  $mail->IsHTML(true);
  $mail->SMTPAuth = true;
  $mail->Username = $set['set_smtp_uname'];
  $mail->Password = $set['set_smtp_pass'];
  $mail->setFrom($set['set_noreply_email'], $set['set_site_name']);
  $mail->addAddress($email, $name);
  $mail->Subject = $sub;
  $mail->Body    = $msg;
  return $mail->Send();  // add return here 
}

尝试使用PHP函数创建时，PHPMailer不起作用
