swiftmailer and email form with attachment - beginner
提问by TryHarder
As always here is the place where I have learned a lot. And I have now a new things to learn:
一如既往，这里是我学到很多东西的地方。我现在有新的东西要学：
I have a html form:
我有一个 html 表单：
<tr><td width="16%">File attachment</td><td width="2%">:</td><td><input type="file" name="fileatt" /></td></tr>
and a mail.php:
和一个mail.php：
$attachfile=$_POST["fileatt"];
and a correct swiftmailer code to send emails out;
和正确的 swiftmailer 代码以发送电子邮件；
I have googled and I found many examples how to send attachment with a file stored on the website but I would like to do it on the fly. So when you submit the button it would send it to peoples out rather than uploading the file.
我用谷歌搜索，我发现了很多例子，如何发送带有存储在网站上的文件的附件，但我想即时完成。因此，当您提交按钮时，它会将其发送给人们而不是上传文件。
// Create the Transport
$transport = Swift_SmtpTransport::newInstance('mail.server.co.uk', 25)
->setUsername('user')
->setPassword('pass')
;
// Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
// Create a message
$message = Swift_Message::newInstance($subject)
->setFrom(array('[email protected]' => 'name'))
->setBody($html, 'text/html')
;
// Add alternative parts with addPart()
$message->addPart(strip_tags($html), 'text/plain');
// Send the message
$result = $mailer->send($message);
could anyone help me how to do the on the fly file uploading, please? Thanks in advance!!!
任何人都可以帮助我如何进行动态文件上传吗？提前致谢！！！

There's a simple way to do this, here you go:
有一个简单的方法可以做到这一点，给你：
$message->attach(
Swift_Attachment::fromPath('/path/to/image.jpg')->setFilename('myfilename.jpg')
);
That's one way SwiftMail can do this, now just the /tmp file, and turn the above into the following:
这是 SwiftMail 可以执行此操作的一种方式，现在只是 /tmp 文件，并将上述内容转换为以下内容：
Assuming: fileatt is the variable for the $_FILE, ['tmp_name'] actually is the tmp file that PHP creates from the form upload.
假设：fileatt 是 $_FILE 的变量，['tmp_name'] 实际上是 PHP 从表单上传创建的 tmp 文件。
$message->attach(
Swift_Attachment::fromPath($_FILES['fileatt']['tmp_name'])->setFilename($_FILES['fileatt']['name'])
);
More information on SwiftMail Attachments can be found on this docspage
可以在此文档页面上找到有关 SwiftMail 附件的更多信息
More information on $_FILES can be found here on w3schools, despite I don't like w3schools, this page is solid.
关于 $_FILES 的更多信息可以在 w3schools 上找到，尽管我不喜欢w3schools，但这个页面是可靠的。

Another way to do this, using only a single variable for path and filename is:
另一种方法是，只使用一个变量作为路径和文件名：
$message->attach(Swift_Attachment::fromPath('full-path-with-attachment-name'));

Single Attachment
单个附件
My answer is similar to that of André Catita. However, in Laravel 6 you can use $requestinstead of $_FILES. Let me simplify the code above:
我的回答与 André Catita 的回答相似。但是，在 Laravel 6 中，您可以使用$request而不是$_FILES。让我简化上面的代码：
$path = $request->file('import')->getPathName();
$fileName = $request->file('import')->getClientOriginalName();
$message->attach(
Swift_Attachment::fromPath($path)->setFilename($fileName)
);
Here I assume that the name of your file tag is import. For eg: <input type="file" name="import" />
在这里，我假设您的文件标签的名称是 import。例如：<input type="file" name="import" />
Multiple Attachments
多个附件
Now, lets say instead of single attachment you need multiple attachments. Then the code needs to be changed.
现在，假设您需要多个附件而不是单个附件。然后需要修改代码。
First your html code will become: <input type="file" name="import[]" multiple />
首先你的 html 代码会变成： <input type="file" name="import[]" multiple />
And for backend or laravel; code will be:
对于后端或 Laravel；代码将是：
$files = $request->file('import');
foreach($files as $file){
$path = $file->getPathName();
$fileName = $file->getClientOriginalName();
$message->attach(
Swift_Attachment::fromPath($path)->setFilename($fileName)
);
}
