Question

我希望能够通过我的联系表单发送多个附件，当我发送任意数量的附件时，我会在fake@fake.com上获得阵列附件。不知道如何让它们作为单独的附件来实现。？

HTML代码

<form id="contact-form" action="contact.php" method="post" enctype="multipart/form-data">
            <div class="row">
                <div>

                            <input type="text" class="form-control" id="name" name="name" placeholder="Enter name" required />

                    </div>

Answer 1

你需要循环文件

我更改了uniqid（）的附件ID：

$body .= "X-Attachment-Id: " . uniqid('email_', true) . "\r\n\r\n";

试试这个，希望能帮到你：

<?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' . "\r\n";
    $headers .= "From: " . $email . "\n";
    $headers .= "Subject:  " . $subject . "\n";
    $headers .= "Content-Type: multipart/mixed; boundary = $boundary\r\n\r\n";

    //plain text
    $body = "--$boundary\r\n";
    $body .= "Content-Type: text/plain; charset=ISO-8859-1\r\n";
    $body .= "Content-Transfer-Encoding: base64\r\n\r\n";
    $body .= chunk_split(
        base64_encode(
            'Name: ' . $name . "\n" . 'Email: ' . $email . "\n" . 'Subject: ' . $subject . "\n" . 'Message: ' . $message
            . "\r\n"
        )
    );

    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
            $body .= "--$boundary\r\n";
            $body .= "Content-Type: $file_type; name=\"$file_name\"\r\n";
            $body .= "Content-Disposition: attachment; filename=\"$file_name\"\r\n";
            $body .= "Content-Transfer-Encoding: base64\r\n";
            $body .= "X-Attachment-Id: " . uniqid('email_', true) . "\r\n\r\n";
            $body .= $encoded_content;
        }
    }

这是您上传的文件结构

Array
(
    [newupload] => Array
        (
            [name] => Array
                (
                    [0] => simple-hotstrings.ahk
                    [1] => 
                    [2] => 
                )

            [type] => Array
                (
                    [0] => application/octet-stream
                    [1] => 
                    [2] => 
                )

            [tmp_name] => Array
                (
                    [0] => T:\Temp\Php\php7A7B.tmp
                    [1] => 
                    [2] => 
                )

            [error] => Array
                (
                    [0] => 0
                    [1] => 4
                    [2] => 4
                )

            [size] => Array
                (
                    [0] => 4775
                    [1] => 0
                    [2] => 0
                )

        )

)

Php表单附件将作为数组而不是文件发送
