Change a function in a class to accept a parameter

Steynsk asked
Last Modified: 2014-05-06
Hi Expert,

I've found this excellent jquery upload script that has a classic asp version. It is called UploadiFy.
With the help of Bib Monty I succeeded to rename the uploaded files.
Ultimate the goal was to add a case number to a uploaded file. So the caseID is for instance 14 and if a "test.jpg" would be uploaded it should be renamed to "14_test.jpg" after being uploaded.

Like I said the renaming part is clear but now I need to parse the caseID from the default.asp to the code that does the renaming part.

There are three main files:


In line 28 of the default.asp

		'script'         	: 'uploader214.asp?sId=<%=session.sessionID%>&caseID=14',

Open in new window

I Parse the caseID using a parameter to the uploader214.asp file.

In line 19 of uploader214.asp :


The Save function of the object gets a called with a path parameter.


Open in new window

This function can be found in the uploaderCLS.asp in line 79

I've tried to change this into:


Open in new window

and receive the value :

      Public Sub Save(path,caseID)

But when I use it get error  aaaHTTP: undifined

Beneath all three files:
