我希望能够用我的联系人表单发送多个附件，当我发送任意数量的附件时，我会在fake@fake.com.不知道如何将它们作为单独的附件。？
HTML代码

PHP
<?php
if($_POST && isset($_FILES['newupload'])) {
$name=$_POST["name"];
$email=$_POST["email"];
$subject=$_POST["subject"];
$newupload=$_POST["newupload"];
$message=$_POST["message"];
$recipient_email = 'fake@fake.com';
//get file details we need
$file_tmp_name = $_FILES['newupload']['tmp_name'];
$file_name = $_FILES['newupload']['name'];
$file_size = $_FILES['newupload']['size'];
$file_type = $_FILES['newupload']['type'];
$file_error = $_FILES['newupload']['error'];
$user_email = filter_var($_POST["email"], FILTER_SANITIZE_EMAIL);
//read from the uploaded file & base64_encode content for the mail
$handle = fopen($file_tmp_name, "r");
$content = fread($handle, $file_size);
fclose($handle);
$encoded_content = chunk_split(base64_encode($content));
$boundary = md5("sanwebe");
//header
$headers = 'MIME-Version: 1.0' . "rn";
$headers .= "From: " .$email. "n";
$headers .= "Subject: " .$subject. "n";
$headers .= "Content-Type: multipart/mixed; boundary = $boundaryrnrn";
//plain text
$body = "--$boundaryrn";
$body .= "Content-Type: text/plain; charset=ISO-8859-1rn";
$body .= "Content-Transfer-Encoding: base64rnrn";
$body .= chunk_split(base64_encode('Name: ' .$name."n".
'Email: ' .$email."n".
'Subject: ' .$subject."n".
'Message: ' .$message."rn"));
//attachment
$body .= "--$boundaryrn";
$body .="Content-Type: $file_type; name="$file_name"rn";
$body .="Content-Disposition: attachment; filename="$file_name"rn";
$body .="Content-Transfer-Encoding: base64rn";
$body .="X-Attachment-Id: ".rand(1000,99999)."rnrn";
$body .= $encoded_content;
$sentMail = @mail($recipient_email, $subject, $body, $headers);
/* Redirect visitor to the thank you page */
header('Location: thanks.html');
exit();
}
?>
您需要循环文件
我更改了uniqid（）的附件id：
$body .= "X-Attachment-Id: " . uniqid('email_', true) . "rnrn";
试试这个，我希望能帮助你：
<?php
if ($_POST && isset($_FILES['newupload'])) {
$name = $_POST["name"];
$email = $_POST["email"];
$subject = $_POST["subject"];
$message = $_POST["message"];
$recipient_email = 'fake@fake.com';
$user_email = filter_var($_POST["email"], FILTER_SANITIZE_EMAIL);
$boundary = md5("sanwebe");
//header
$headers = 'MIME-Version: 1.0' . "rn";
$headers .= "From: " . $email . "n";
$headers .= "Subject: " . $subject . "n";
$headers .= "Content-Type: multipart/mixed; boundary = $boundaryrnrn";
//plain text
$body = "--$boundaryrn";
$body .= "Content-Type: text/plain; charset=ISO-8859-1rn";
$body .= "Content-Transfer-Encoding: base64rnrn";
$body .= chunk_split(
base64_encode(
'Name: ' . $name . "n" . 'Email: ' . $email . "n" . 'Subject: ' . $subject . "n" . 'Message: ' . $message
. "rn"
)
);
for ($i = 0; $i < 3; $i++) {
if (!empty($_FILES['newupload']['name'][$i])) {
//read from the uploaded file & base64_encode content for the mail
//get file details we need
$file_tmp_name = $_FILES['newupload']['tmp_name'][$i];
$file_name = $_FILES['newupload']['name'][$i];
$file_size = $_FILES['newupload']['size'][$i];
$file_type = $_FILES['newupload']['type'][$i];
$file_error = $_FILES['newupload']['error'][$i];
$handle = fopen($file_tmp_name, "r");
$content = fread($handle, $file_size);
fclose($handle);
$encoded_content = chunk_split(base64_encode($content));
//attachment
$body .= "--$boundaryrn";
$body .= "Content-Type: $file_type; name="$file_name"rn";
$body .= "Content-Disposition: attachment; filename="$file_name"rn";
$body .= "Content-Transfer-Encoding: base64rn";
$body .= "X-Attachment-Id: " . uniqid('email_', true) . "rnrn";
$body .= $encoded_content;
}
}
