how to attach multiple files to email using scala and liftweb - scala

Question

I'm trying to attach multiple files I'm writing REST Service for that but the files are not loading
my code look like below:-
HTML:-
<form action="DemoEmailAttachment" method="post">
To: <input type="text" name="to"><br>
Subject: <input type="text" name="subject"><br>
Body:<textarea rows="4" cols="50" name="body"></textarea><br>
AttachFiles:<input type="file" name="fileupload" multiple="multiple"><br>
<input type="submit" value="Send">
</form>
SCALA:-
object demoAttachment {
def sendAtchMail(request: Req) = {
val obj = request._params
println(obj)
LiftRules.handleMimeFile = OnDiskFileParamHolder.apply
val fileupload = request.uploadedFiles
println(fileupload)
val to = (obj.get("to").get)(0).split(",")
val subject = obj.get("subject").get
val body = obj.get("body").get
case class CSVFile(bytes: Array[Byte],filename:String,mime:String )
var data = Array[Byte]()
println(data.length)
val ls = fileupload.map(c => c match {
case ff:OnDiskFileParamHolder => { ff.fileStream.read(data)
val attach = CSVFile(data,ff.fileName,ff.mimeType)
val msg = XHTMLPlusImages(<p>Please research the enclosed. </p>,PlusImageHolder(attach.filename, attach.mime, attach.bytes))
Mailer.sendMail(
From("536#gmail.com"),
Subject(subject(0)),
To(to(0)),
msg
)
}
case _ => "there are no files"
} )
"success"
}
}

Answer 1

The XHTMLPlusImages constructor takes a vararg for the attachment parameter. So, just pass in multiple attachments, like this:
XHTMLPlusImages(NodeSeq, attach1, attach2, attach3, ...)
Also, you should verify that data actually contains what you are looking send. Unless I am mistaken, the way you are reading the data from the stream will only read in however many bytes your Array[Byte] can hold, which is probably 0. There is a good answer here that discusses reading from the InputStream to a ByteArray.
