使用 SwiftMailer 和 PHP 检索要附加到电子邮件的文件名 [英] Retrieving a file name to attach to an email with SwiftMailer and PHP

问题描述

我昨天问了这个问题并得到了一个建议，并使用了它，但由于某种原因它不起作用.因此，我需要检索用户从 HTML 表单上传到我的服务器的文件的名称.我需要将此文件附加到由 PHP/SwiftMailer 发送的电子邮件中.这是我的代码，文件上传部分:

I asked the question yesterday and got an advice, and used it, but it doesn't work for some reason. So, I need to retrieve the name of the file that was uploaded to my server from an HTML form by a user. I need this file to be attached to an email that is to be sent by PHP/SwiftMailer. Here is my code, the file upload portion:

    //File upload

// Where the file is going to be placed 
$target_path = "uploads/";

// Add the original filename to our target path.  
//Result is "uploads/filename.extension" 
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']). 
    " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
}   

//End of file upload

这是文件附加部分:

//Create the attachment
$attachment = Swift_Attachment::fromPath($_FILES['uploadedfile']['tmp_name']);

为什么不从服务器获取文件?这是错误消息，看起来它试图在错误的目录中查找文件:

Why doesn't it get the file from the server? Here is the error message, and it looks like it's trying to find the file in a wrong directory:

警告:fopen(/tmp/phpHJdw0H)[function.fopen]:打开失败流:没有这样的文件或目录/home/myserver/mydomain.com/Hawaii/html/swift-mailer/lib/classes/Swift/ByteStream/FileByteStream.php在第 131 行致命错误:在/home/myserver/mydomain.com/Hawaii/html/swift-mailer/lib/classes/Swift/ByteStream/中出现消息无法打开文件以读取 [/tmp/phpHJdw0H]"的未捕获异常Swift_IoException"FileByteStream.php:133 堆栈跟踪:#0
等

etc.

谢谢！

推荐答案

使用:

$attachment = Swift_Attachment::fromPath($target_path);

这是因为您已将文件从其临时位置移动，$_FILES['uploadedfile']['tmp_name'] 返回您使用 move_uploaded_file.这假设 $target_path 在 swift 邮件程序代码的范围内

This is because you have moved the file from its temporary location, $_FILES['uploadedfile']['tmp_name'] returns the path from before you moved the file using move_uploaded_file. This assumes the $target_path is within scope to the swift mailer code
