Send Email with Multiple Attachments using PHP

In this tutorial, we are going to learn about sending an email with multiple attachments. We will be using the PHPMailer. The attachment files are chosen and attached to the email via an HTML form. I have used jQuery AJAX to call the mail script by posting email data with the attachments. If you are looking for a email with single attachment, refer my previous tutorial, how to send an email by using PHPMailer class


In this example, I have created an HTML form containing input fields for Sender Name, Email, SubjectContent and Files to be attached. In this form, the file input field is set with the “multiple” attribute to allow choosing more than one file for the email attachment. The chosen files in the $_FILES global array are iterated and attached to the email by using PHPMailer object. Previously, we have seen an example of sending contact email with a single attachment.

Choosing Multiple Attachments using HTML Form 

The following HTML form contains input fields for entering email data like name and email of the sender, the subject and the body content. It also contains file input for choosing more than one file by enabling the “multiple” property.

<form id="frmEnquiry" action="" method="post" enctype='multipart/form-data'>
    <div id="mail-status"></div>
            type="text" name="userName" id="userName"
            class="demoInputBox" placeholder="Name">
        <input type="text" name="userEmail" id="userEmail"
            class="demoInputBox" placeholder="Email">
        <input type="text" name="subject" id="subject"
            class="demoInputBox" placeholder="Subject">
        <textarea name="content" id="content" class="demoInputBox"
            cols="60" rows="6" placeholder="Content"></textarea>
        <label>Attachment</label><br /> <input type="file"
            name="attachment[]" class="demoInputBox" multiple="multiple">
        <input type="submit" value="Send" class="btnAction" />

Posting Form Data via jQuery AJAX

On submitting the form, the value of the input fields entered by the user is validated using jQuery. If all the fields are validated and the validation function returns true, then AJAX call will be generated for requesting the email sending script. After executing the mail script, the AJAX response block will update the UI to acknowledge the user about the sent status of the email.

<script src="jquery-3.2.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function (e){
	var valid;	
	valid = validateContact();
	if(valid) {
		url: "mail-send.php",
		type: "POST",
		data:  new FormData(this),
		contentType: false,
		cache: false,
		success: function(data){
		error: function(){} 	        

function validateContact() {
	var valid = true;	
	if(!$("#userName").val()) {
        valid = false;
    if(!$("#userEmail").val()) {
        valid = false;
    if(!$("#userEmail").val().match(/^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/)) {
        $("#userEmail").attr("title","Invalid Email");
        valid = false;
	if(!$("#subject").val()) {
		valid = false;
	if(!$("#content").val()) {
		valid = false;
	return valid;


PHP Code to Attach Multiple Files to the EMail

In this PHP code, it creates the mail object for the PHPMailer class. Using this object, the email options are set before invoking the send function.

The multiple files posted via the HTML form will be read by using $_FILES array variable. This array is iterated the corresponding file will be attached by calling the addAttachment() function with the reference of the mail object.


$mail = new PHPMailer();
$mail->SMTPDebug = 0;
$mail->SMTPAuth = TRUE;
$mail->SMTPSecure = "ssl";
$mail->Port     = 465;  
$mail->Username = "YOUR USER_NAME";
$mail->Password = "YOUR PASSWORD";
$mail->Host     = "YOUR HOST";
$mail->Mailer   = "smtp";
$mail->SetFrom($_POST["userEmail"], $_POST["userName"]);
$mail->AddReplyTo($_POST["userEmail"], $_POST["userName"]);
$mail->Subject = $_POST["subject"];
$mail->WordWrap   = 80;

foreach ($_FILES["attachment"]["name"] as $k => $v) {
    $mail->AddAttachment( $_FILES["attachment"]["tmp_name"][$k], $_FILES["attachment"]["name"][$k] );


if(!$mail->Send()) {
	echo "<p class='error'>Problem in Sending Mail.</p>";
} else {
	echo "<p class='success'>Mail Sent Successfully.</p>";

HTML Form with Multiple File Attachment Screenshot
