如何使用以下代码通过 phpmailer 集成附加文件
How to integrate attach file via phpmailer with the following code
我正在尝试通过 phpmailer 发送一个名为 proposal 的文件。但这似乎不起作用。我似乎无法使 $_FILES 工作或将 isset 与 $_POST 一起应用于它。请帮忙。提前谢谢你。
这是 HTML 文件：
PHP 包含在 html
之上
<?php
session_start(); //to access errors from form_process.php
require_once '../helper/security.php'; //include security php
require_once("../includes/config.php");
$errors = isset($_SESSION['errors']) ? $_SESSION['errors'] : [];
$fields = isset($_SESSION['fields']) ? $_SESSION['fields'] : [];
$success = isset($_SESSION['success']);
$pageTitle = "valhalla | Franchise";
$pageId = "franchise";
include(ROOT_PATH . "includes/header.php");
?>

对于 SO 问题，您发布的内容太多了，但我想我还是发现了您的问题。您的表单标签缺少允许文件上传的 MIME 类型。而不是：
<form name="franchise" method="post" action="<?php echo BASE_URL; ?>mail/form_process_franchise.php">
你需要：
<form name="franchise" method="post" enctype="multipart/form-data" action="<?php echo BASE_URL; ?>mail/form_process_franchise.php">
您还需要一个 MAX_FILE_SIZE 元素：
<input type="hidden" name="MAX_FILE_SIZE" value="300000">
将值更改为适合您预期上传的值。
之后你需要阅读 PHPMailer 提供的 PHP docs on handling uploads, and the send_file_upload 示例，但简短的版本是你需要使用 move_uploaded_file 来确保你的上传是安全的在尝试使用它们之前。
所有这些都可以在 PHP 中有关处理文件上传的任何初级教程中找到，因此请在以后发帖前进行搜索。
