I’m trying to attach an Excel file in a SwiftMailer message.
The trick is that I don’t want to save the excel file and then attach it and then delete it, instead I just want to generate the excel and attach that to the message.
This function allows to attach a OutputByteStream
/** * Create a new Attachment. * * @param string|Swift_OutputByteStream $data * @param string $filename * @param string $contentType * * @return Swift_Mime_Attachment */ public static function newInstance($data = null, $filename = null, $contentType = null) { return new self($data, $filename, $contentType); }
There is a function in Symfony PHPExcel bundle to create the response
/** * Stream the file as Response. * * @param PHPExcel_Writer_IWriter $writer * @param int $status * @param array $headers * * @return StreamedResponse */ public function createStreamedResponse(PHPExcel_Writer_IWriter $writer, $status = 200, $headers = array()) { return new StreamedResponse( function () use ($writer) { $writer->save('php://output'); }, $status, $headers ); }
They seems to call to that callback when they are rendering the reponse, but How can I save the php://output in a variable or something to pass it to newInstance method?
I tried passing the response object (StreamedResponse) but it only have the headers, I also tried with $response->getContent() and passing $writer->save(‘php://output’) to newInstance method.

Answer
use stream_get_contents
$attachment = Swift_Attachment::newInstance(stream_get_contents(createStreamedResponse(...)), 'test.xls', 'application/vnd.ms-excel');
(dont know hat your actual mimetype is)
