Send Mail Attachments with PHP Mail() Demo
Mail send with attachments in PHP step by step:
- First, we create a simple HTML form with form attribute
enctype="multipart/form-data" - Creating some HTML input box, textarea and for attachment input
type="file" - Then we start with PHP code to send email with attachment.
Creating HTML Form
|
1 2 3 4 5 6 7 8 9 |
<form method="post" enctype="multipart/form-data"> <input type="text" id="contact_name" class="form-control" placeholder="Name" name="user_name"/> <input type="text" id="contact_email" class="form-control" placeholder="Email Address" name="user_mail"> <textarea id="contact_message" class="form-control" rows="7" placeholder="Write a message" name="user_message"></textarea> <input name="attachment" type="file"> <input type="submit" value="Send mail" class="btn btn-primary pull-right"/> </form> |
On the above form
enctype="multipart/form-data", this attribute is important for sending attachment.
PHP code to send email with attachment
- First, we post all the data from the HTML Form using
$_POSTfunction. - Also, post the attachment using name attribute of that field.
- For uploading file input type must have
type="file"
|
1 2 3 4 5 6 7 8 |
<?php if(isset($_POST) && !empty($_POST)) { if(!empty($_FILES['attachment']['name'])) { $file_name = $_FILES['attachment']['name']; $temp_name = $_FILES['attachment']['tmp_name']; $file_type = $_FILES['attachment']['type']; $base = basename($file_name); |
- Checking allowed an extension on below code,
|
1 2 3 4 |
$extension = substr($base, strlen($base)-4, strlen($base)); //only these file types will be allowed $allowed_extensions = array(".doc", "docx", ".pdf", ".zip", ".png"); |
- If the file has satisfy allowed an extensions then go to next step,

//check that this file type is allowed if(in_array($extension,$allowed_extensions)) { //mail essentials $from = $_POST['user_mail']; $to = $_POST['user_mail']; $subject = $_POST['user_name']; $message = $_POST['user_message']; //things u need $file = $temp_name; $content = chunk_split(base64_encode(file_get_contents($file))); $uid = md5(uniqid(time())); //unique identifier //standard mail headers $header = "From: ".$from."\r\n"; $header .= "Reply-To: ".$replyto. "\r\n"; $header .= "MIME-Version: 1.0\r\n"; //declare multiple kinds of email (plain text + attch) $header .="Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n"; $header .="This is a multi-part message in MIME format.\r\n"; //plain txt part $header .= "--".$uid."\r\n"; $header .= "Content-type:text/plain; charset=iso-8859-1\r\n"; $header .= "Content-Transfer-Encoding: 7bit\r\n"; $header .= $message. "\r\n"; //attch part $header .= "--".$uid."\r\n"; $header .= "Content-Type: ".$file_type."; name=\"".$file_name."\"\r\n"; $header .= "Content-Transfer-Encoding: base64\r\n"; $header .= "Content-Disposition: attachment; filename=\"".$file_name."\"\r\n"; $header .= $content."\r\n"; //chucked up 64 encoded attch //sending the mail - message is not here, but in the header in a multi part if(mail($to, $subject, $message, $header)) { echo "success"; }else { echo "fail"; echo error_get_last()['message']; } }else { echo "file type not allowed"; } //echo an html file }else { echo "no file posted"; } } ?> |
On the above PHP code, we create mail headers for sending PHP mail attachment.
