Discuss "Free ASP Upload Question" in the ASP Development forum.

All,

Ok, I've uploaded this on a development server to try to figure out how it works and such....

1) I noticed I can upload the same file twice.....It looks it just gets overwritten each time. How / where can I begin to stop this? Because I don't want it to overwrite if user1 submits file name "pic1.jpg" and user2 submits file name "pic1.jpg".

tried to add this but not working Upload.OverwriteFiles = False.

Reason: I'm going to have a form where I want to allow 2 files (max) to be uploaded but at the same time I will take all other fields in the form and insert them into a database and I would like to somehow link the files attached to the inserted record.

So later after I've submitted a form (fields and 2 files) then I can search and see that form data with those pictures.

Here is what I try but get error below after code(line in red):

Code:

function SaveFiles
    Dim Upload, fileName, fileSize, ks, i, fileKey

    Set Upload = New FreeASPUpload
    Upload.OverwriteFiles(uploadsDirVar) = False    

Upload.Save(uploadsDirVar)

Code:

Microsoft VBScript runtime error '800a01b6' 

Object doesn't support this property or method: 'Upload.OverwriteFiles'

Although I don't use FreeASPUpload, I use the following logic to check if the file already exists.

In my case I can check the filename property before calling the save method. I'm not sure you can do that with this script, so you may have to upload to a temp folder first.

Get the filename(s) using something like:-

Code:

objUpload.UploadedFiles("name_of_form_element").FileName
Set FSO = Server.CreateObject("Scripting.FileSystemObject")

Then use FSO to check if the file exists in your "real" upload folder.

Code:

If FSO.FileExists(server.mappath("path_to_your_final_upload_folder")) = True then
'File already exists
else
'File doesnot exist
end if
Set FSO = Nothing

If you can't get the filenames without calling the Save method first, then if the file doesn't exist, you can then use the same FSO object to move the file to the correct folder and delete it from the temp folder.

If it does exist then you can write a message to the screen.

Hope that helps.

There's a section of the freeaspuload code that looks like this:

Code:

Public Sub Save(path)
    Dim streamFile, fileItem

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

    if not uploadedYet then Upload

    For Each fileItem In UploadedFiles.Items
      Set streamFile = Server.CreateObject("ADODB.Stream")
      streamFile.Type = 1
      streamFile.Open
      StreamRequest.Position=fileItem.Start
      StreamRequest.CopyTo streamFile, fileItem.Length
      streamFile.SaveToFile path & fileItem.FileName, 2
      streamFile.close
      Set streamFile = Nothing
      fileItem.Path = path & fileItem.FileName
     Next
  End Sub

try changing that section to this:

Code:

Public Sub Save(path)
    Dim streamFile, fileItem
    if Right(path, 1) <> "\" then path = path & "\"
    if not uploadedYet then Upload
    Dim newFileName, fs ' declare new empty variables
    set fs=Server.CreateObject("Scripting.FileSystemObject") ' set 1 variable to be the file system object (which has the power to manipulate files)
    For Each fileItem In UploadedFiles.Items ' loop through each file that's been uploaded when the page was submitted
      newFileName = fileItem.FileName ' assign the file name to check to be this file's name
      if fs.FileExists(path & newFileName) then ' use the file system object to check the current file's existence
         response.write("<span class=""color:#ff0000;"">" & newFileName & " exists and could not be saved; please rename and try again.</span>") ' the file exists so through an error
      else
         Set streamFile = Server.CreateObject("ADODB.Stream") ' do the normal save stuff that was there before
         streamFile.Type = 1
         streamFile.Open
         StreamRequest.Position=fileItem.Start
         StreamRequest.CopyTo streamFile, fileItem.Length
         streamFile.SaveToFile path & newFileName, 2
         streamFile.close
         Set streamFile = Nothing
         fileItem.Path = path & newFileName
      end if
    Next
End Sub

let me know how it works for you.

glad it worked for you ... although it wasn't my code, i found it on another site awhile ago and it's part of my code bank.
