Question

我正在使用Filepond（https://pqina.nl/filepond/）将文件上传到服务器上。我能够使用php样板（https://github.com/pqina/filepond-server-php）并能够使用filepond上传我的文件，但想知道如何用phpMailer发送它？如何将此代码（Rik的send.php）与phpMailer结合在一起？

我注意到下面的这段代码将文件放在服务器上。顺便说一句，我不需要存储它，我只想到达temp文件夹并发送它。可以删除之后...

<?php

// Comment if you don't want to allow posts from other domains
header('Access-Control-Allow-Origin: *');

// Allow the following methods to access this file
header('Access-Control-Allow-Methods: POST');

// Load the FilePond class
require_once('FilePond.class.php');

// Load our configuration for this server
require_once('config.php');

// Catch server exceptions and auto jump to 500 response code if caught
FilePond\catch_server_exceptions();
FilePond\route_form_post(ENTRY_FIELD, [
    'FILE_OBJECTS' => 'handle_file_post',
    'BASE64_ENCODED_FILE_OBJECTS' => 'handle_base64_encoded_file_post',
    'TRANSFER_IDS' => 'handle_transfer_ids_post'
]);

function handle_file_post($files) {

    // This is a very basic implementation of a classic PHP upload function, please properly
    // validate all submitted files before saving to disk or database, more information here
    // http://php.net/manual/en/features.file-upload.php

    foreach($files as $file) {
        FilePond\move_file($file, UPLOAD_DIR);
    }
}

function handle_base64_encoded_file_post($files) {

    foreach ($files as $file) {

        // Suppress error messages, we'll assume these file objects are valid
        /* Expected format:
        {
            "id": "iuhv2cpsu",
            "name": "picture.jpg",
            "type": "image/jpeg",
            "size": 20636,
            "metadata" : {...}
            "data": "/9j/4AAQSkZJRgABAQEASABIAA..."
        }
        */
        $file = @json_decode($file);

        // Skip files that failed to decode
        if (!is_object($file)) continue;

        // write file to disk
        FilePond\write_file(
            UPLOAD_DIR,
            base64_decode($file->data),
            FilePond\sanitize_filename($file->name)
        );
    }

}

function handle_transfer_ids_post($ids) {

    foreach ($ids as $id) {

        // create transfer wrapper around upload
        $transfer = FilePond\get_transfer(TRANSFER_DIR, $id);

        // transfer not found
        if (!$transfer) continue;

        // move files
        $files = $transfer->getFiles(defined('TRANSFER_PROCESSOR') ? TRANSFER_PROCESSOR : null);
        foreach($files as $file) {
            FilePond\move_file($file, UPLOAD_DIR);
        }

        // remove transfer directory
        FilePond\remove_transfer_directory(TRANSFER_DIR, $id);
    }

}

这是两个单独的操作：

从远程位置获取文件
将其作为附件添加到电子邮件中

使用PHPMailer做到这一点的最直接的方法：

$path = tempnam(sys_get_temp_dir(), 'emailfile');
if (file_put_contents($path, file_get_contents('https://example.com/path/to/file.png'))) {
    $mail->addAttachment($path);
}

请注意，PHPMailer明确避免自己成为HTTP客户端； addAttachment()将不接受远程URL，仅接受本地路径。使用适当的HTTP客户端类（例如guzzle）来获取数据并将其存储在文件中，然后将路径名传递给PHPMailer。

或者，您可以将远程内容作为二进制字符串获取，并通过addStringAttachment()将其传递给PHPMailer，这避免了写入磁盘，尽管您应该只对知道适合内存的小物件这样做。 / p>
