使用PHP和Sendgrid API發送表單文件附件

Question

下面是使用phpmailer通過php sendmail發送電子郵件的腳本。我想使用Sendgrid的API發送電子郵件，爲了使它與Sendgrid一起工作，我需要做些什麼改變？

<?php 

require('PHPMailer/class.phpmailer.php'); 

if(isset($_POST['email'])) { 
    $name = $_POST['name']; // required 
    $position = $_POST['position']; // required 
    $email_from = $_POST['email']; // required 
    $phone = $_POST['phone']; // not required 
    $comments = $_POST['comments']; // required 

    $email_to = "careers@site.com"; 
    $name_to = "careers"; 
    $email_subject = "Job Application from ".$name." for ".$position; 

    if($position != null) 
    function clean_string($string) { 
     $bad = array("content-type","bcc:","to:","cc:","href"); 
     return str_replace($bad,"",$string); 
    } 
    $email_message = ""; 
    $email_message .= "Name: ".clean_string($name)."\n"; 
    $email_message .= "Position: ".clean_string($position)."\n"; 
    $email_message .= "Email: ".clean_string($email_from)."\n"; 
    $email_message .= "Phone: ".clean_string($phone)."\n"; 
    $email_message .= "Comments: ".clean_string($comments)."\n"; 

    $allowedExts = array("doc", "docx", "xls", "xlsx", "pdf"); 
$temp = explode(".", $_FILES["file"]["name"]); 
$extension = end($temp); 
if ((($_FILES["file"]["type"] == "application/pdf") 
|| ($_FILES["file"]["type"] == "application/msword") 
|| ($_FILES["file"]["type"] == "application/excel") 
|| ($_FILES["file"]["type"] == "application/vnd.ms-excel") 
|| ($_FILES["file"]["type"] == "application/x-excel") 
|| ($_FILES["file"]["type"] == "application/x-msexcel") 
|| ($_FILES["file"]["type"] == "application/vnd.openxmlformats-officedocument.wordprocessingml.document") 
|| ($_FILES["file"]["type"] == "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")) 

&& in_array($extension, $allowedExts)) 
    { 
    if ($_FILES["file"]["error"] > 0) 
    { 
    echo "<script>alert('Error: " . $_FILES["file"]["error"] ."')</script>"; 
    } 
    else 
    { 
     $d='upload/'; 
     $de=$d . basename($_FILES['file']['name']); 
    move_uploaded_file($_FILES["file"]["tmp_name"], $de); 
$fileName = $_FILES['file']['name']; 
    $filePath = $_FILES['file']['tmp_name']; 
    //add only if the file is an upload 
    } 
    } 
else 
    { 
    echo "<script>alert('Invalid file')</script>"; 
    } 

// create email headers 
$headers = 'From: '.$email_from."\r\n". 
'Reply-To: '.$email_from."\r\n" . 
'X-Mailer: PHP/' . phpversion(); 
//Create a new PHPMailer instance 
$mail = new PHPMailer(); 
//Set who the message is to be sent from 
$mail->SetFrom($email_from, $name); 
//Set an alternative reply-to address 
$mail->addReplyTo($email_from, $name); 
//Set who the message is to be sent to 
$mail->addAddress($email_to, $name_to); 
//Set the subject line 
$mail->Subject = $email_subject; 
//Read an HTML message body from an external file, convert referenced images to embedded, convert HTML into a basic plain-text alternative body 
$mail->MsgHTML($email_message); 
//Replace the plain text body with one created manually 
$mail->AltBody = $email_message; 
//Attach an image file 
$mail->AddAttachment($_FILES['file']['tmp_name'], $_FILES['file']['name']); 
//Send the message, check for errors 
if(!$mail->Send()) { 
    echo "<script>alert('Mailer Error: " . $mail->ErrorInfo."')</script>"; 
} else { 
    echo "<script>alert('Your request has been submitted. We will contact you soon.')</script>"; 
} 
} 
?> 

Answer 1

由於hackeronesaid，改變你的代碼與SendGrid和PHPMailer的發送，你需要更新你的代碼實例化的PHPMailer後，包括SMTP設置。以下設置將與SendGrid一起使用：

// This should go somewhere after $mail = new PHPMailer(); 
$mail->isSMTP();          // Set mailer to use SMTP 
$mail->Host = 'smtp.sendgrid.net';     // Specify server 
$mail->SMTPAuth = true;        // Enable SMTP authentication 
$mail->Username = 'your_sendgrid_username';   // SMTP username 
$mail->Password = 'your_sendgrid_password';   // SMTP password 
$mail->Port = 587;         // Recommended Port 
$mail->SMTPSecure = 'tls';       // Enable encryption, 'ssl'

以下是來自phpmailer的代碼，您可以在實例化PHPmailer後指定sendgrid smtp params。

$mail->isSMTP();          // Set mailer to use SMTP 
$mail->Host = 'smtp1.example.com;smtp2.example.com'; // Specify main and backup server 
$mail->SMTPAuth = true;        // Enable SMTP authentication 
$mail->Username = 'jswan';       // SMTP username 
$mail->Password = 'secret';       // SMTP password 
$mail->SMTPSecure = 'tls';       // Enable encryption, 'ssl' also accepted
