Attaching Dynamic Content

Files that are generated at runtime, such as PDF documents or images created via GD can be attached directly to a message without writing them out to disk. Use the standard Swift_Attachment::newInstance() method.

1. Create your content as you normally would.
2. Create an attachment with Swift_Attachment::newInstance(), specifying the source data of your content along with a name and the content-type.
3. Add the attachment to the message with attach().

//Create your file contents in the normal way, but don't write them to disk
$data = create_my_pdf_data();

//Create the attachment with your data
$attachment = Swift_Attachment::newInstance($data, 'my-file.pdf', 'application/pdf');  

//Attach it to the message
$message->attach($attachment);


//You can alternatively use method chaining to build the attachment
$attachment = Swift_Attachment::newInstance()
  ->setFilename('my-file.pdf')
  ->setContentType('application/pdf')
  ->setBody($data)
  ;
