wordpress - Wordpress：邮件程序错误：无法实例化邮件功能

问题描述

我正在使用 PHP 邮件程序在 wordpress 上发送电子邮件。我放了一个简单的代码来测试这个类是否有效。不幸的是我得到了下面的错误。

include_once(ABSPATH . WPINC . '/class-phpmailer.php');

//PHPMailer Object
 $mail = new PHPMailer;

//From email address and name
$mail->From = "from@yourdomain.com";
$mail->FromName = "Full Name";

//To address and name
$mail->addAddress("recepient1@example.com", "Recepient Name");
$mail->addAddress("recepient1@example.com"); //Recipient name is optional

//Address to which recipient will reply
$mail->addReplyTo("reply@yourdomain.com", "Reply");


//Send HTML or Plain Text email
$mail->isHTML(true);

$mail->Subject = "Subject Text";
$mail->Body = "<i>Mail body in HTML</i>";
$mail->AltBody = "This is the plain text version of the email content";

if(!$mail->send())
{
echo "Mailer Error: " . $mail->ErrorInfo;
}
else
{
 echo "Message has been sent successfully";
 }

我收到以下错误：

Mailer Error: Could not instantiate mail function.

解决方案

尝试使用 SMTP 发送电子邮件：-

<?php
require_once('../class.phpmailer.php');

$mail = new PHPMailer(true); // the true param means it will throw exceptions on errors, which we need to catch

$mail->IsSMTP(); // telling the class to use SMTP

try {
  $mail->Host       = "mail.yourdomain.com"; // SMTP server
  $mail->SMTPDebug  = 2;                     // enables SMTP debug information (for testing)
  $mail->SMTPAuth   = true;                  // enable SMTP authentication
  $mail->Host       = "mail.yourdomain.com"; // sets the SMTP server
  $mail->Port       = 26;                    // set the SMTP port for the GMAIL server
  $mail->Username   = "yourname@yourdomain"; // SMTP account username
  $mail->Password   = "yourpassword";        // SMTP account password
  $mail->AddReplyTo('name@yourdomain.com', 'First Last');
  $mail->AddAddress('whoto@otherdomain.com', 'John Doe');
  $mail->SetFrom('name@yourdomain.com', 'First Last');
  $mail->AddReplyTo('name@yourdomain.com', 'First Last');
  $mail->Subject = 'PHPMailer Test Subject via mail(), advanced';
  $mail->AltBody = 'To view the message, please use an HTML compatible email viewer!'; // optional - MsgHTML will create an alternate automatically
  $mail->MsgHTML(file_get_contents('contents.html'));
  $mail->AddAttachment('images/phpmailer.gif');      // attachment
  $mail->AddAttachment('images/phpmailer_mini.gif'); // attachment
  $mail->Send();
  echo "Message Sent OK</p>\n";
} catch (phpmailerException $e) {
  echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
  echo $e->getMessage(); //Boring error messages from anything else!
}
?>
