Question

我想使用SendGrid SMTP服务从我网站的联系表单发送电子邮件。表单上的提交按钮只是吐出我的网站的空白版本，没有电子邮件发送到我的收件箱。

这是PHP代码：

<?php

require("class.phpmailer.php");
    $mail = new PHPMailer();

    // SMTP & Sendgrid settings
    $mail->IsSMTP();
    $mail->Host = "smtp.sendgrid.net";
    $mail->Port = "465";
    $mail->SMTPAuth = "true";   // Enable SMTP authentication
    $mail->Username = "sendgrid username";
    $mail->Password = "sendgrid password";
    $mail->SMTPSecure = ''; // Enable encryption, 'ssl' also accepted

    // Email headers and body
    $mail->SetFrom("abc@123.com");
    $mail->AddAddress("abc@123.com");

    // Form fields
        $Name = $_POST['Name'];
        $Email = $_POST['Email'];
        $Contact = $_POST['Contact'];
        $Message = $_POST['Message'];


    $mail->Subject  = "Message from yoursite.com";
    $mail->Body     = "You have a new message from your contact form on site.com \n \n Name: $Name \n Email: $Email \n Contact: $Contact \n Message: $Message";
    $mail->WordWrap = 50;


    if(!$mail->Send()) {
      echo 'Message was not sent.';
      echo 'Mailer error: ' . $mail->ErrorInfo;
    }
    else {
      echo 'Message has been sent.';
    }
header('Location: mywebsite.com');
 ?>

以下是使用SendGrid API发送电子邮件的分步过程，

从Download Packaged Library下载已归档的SendGrid库。解压缩并将其放入项目目录中。
转到https://app.sendgrid.com/settings/api_keys并为您的帐户/应用程序创建API密钥。

现在来到编码部分。以下列方式重构您的代码，

require_once('sendgrid-php/sendgrid-php.php');

$from = new SendGrid\Email(null, "SENDER'S_EMAIL_ADDRESS");
$subject = "Hello World from the SendGrid PHP Library!";
$to = new SendGrid\Email(null, "RECEIVER'S EMAIL ADDRESS");
$content = new SendGrid\Content("text/plain", "Hello, Email!");
$mail = new SendGrid\Mail($from, $subject, $to, $content);

$apiKey = 'YOUR_API_KEY';
$sg = new \SendGrid($apiKey);

$response = $sg->client->mail()->send()->post($mail);
if($response->statusCode() == 202){
    echo "Email sent successfully";
}else{
    echo "Email could not be sent";
}

请勿忘记根据您的要求更改SENDER'S_EMAIL_ADDRESS，RECEIVER'S_EMAIL_ADDRESS和YOUR_API_KEY。最重要的是，根据您的应用程序要求更改电子邮件的主题和正文。

旁注：如果中途出现任何问题，请使用以下三种响应方法进行调试。

echo $response->statusCode();
var_dump($response->headers());
echo $response->body();
