Rename a file using the upload tool Uploadify

Hi Experts,

I've found this wonderful code that does the job for me. It is the classic ASP version of Uploadify.

Now I'd like to add simple rename action for each file that gets uploaded. In my default page I've set a variable caseID and for testing purposes I've given it the value "10"
Now I'd like to change the uploaded file name so it starts with this number and a underscore. So if my file is called "test.jpg" it should be renamed to "10_test.jpg"

Could this be done somewhere in the code of this page (see code)?

<%
caseID="10"
application("sessionID")=Session.SessionID
application("uploadpath")="userfiles"
%>

the easiest way would be to do it on the server side, wherever you process the files:

Dim fso
Set fso = CreateObject("Scripting.FileSystemObject")
fso.MoveFile "d:\dummytest.txt", "d:\dummytest2.txt"

Hi Big Monty,

Thank you for your quick response. Looking at your response I conclude that I had to ask where in the code should I put this rename action?

Could you please tell me where this action should be put within the ASP files?

Kind regards,

Steynsk

you could create a function in the FreeASPUpload class like this (just make sure you back up the file beforehand):

Public Sub Save(path)
		Dim streamFile, fileItem, filePath

		if Right(path, 1) <> "\" then path = path & "\"

		if not uploadedYet then Upload

		For Each fileItem In UploadedFiles.Items
			filePath = path & fileItem.FileName
			Set streamFile = Server.CreateObject("ADODB.Stream")
			streamFile.Type = adTypeBinary
			streamFile.Open
			StreamRequest.Position=fileItem.Start
			StreamRequest.CopyTo streamFile, fileItem.Length
			streamFile.SaveToFile filePath, adSaveCreateOverWrite
			streamFile.close
			Set streamFile = Nothing
			fileItem.Path = filePath

Dim fso, newFile
Set fso = CreateObject("Scripting.FileSystemObject")
newFile = "pathAndNewFileName.txt"
fso.MoveFile filePath, newFile
set fso = nothing
		 Next
	End Sub
%>

Thanks again for your quick response. And yes this works but how do I parse the caseID variable to this file?

you could change the Save function in the class to accept it as a parameter
