Restricting File Uploads

Guest · Mar 15, 2005

Hi all,
Is there any way it is possible to restrict the type of file uploaded using
the file upload function within a form?

I need to force users to upload files of one type i.e .jpg as uploading .bmp
images is causing problems with the forum software I am using (apart from the
obvious file size implications)

Thanks for taking the time to read this posting. Andy

Not with the std FP file upload component

Check w/ your host to see if they support ASP and a File Upload component
You could do an ASP file upload and add ASP to delete all but .jpg files (after the upload)
- if the host supports a file use their script recommendation
Otherwise See http://support.microsoft.com/kb/299692/EN-US/

Then modify the code for the UploadFile.asp to be

If Err.number = 0 Then
For Each File in fuFile.Files
Ext = UCase(Right(fuFile.FileName, 3))
If Ext <> "JPG" Then
File.Delete
strMsg = "Illegal File NOT UpLoaded"
Else
strMsg = fuFile.FileName & " was uploaded successfully."
End If
Next
Else
.... .....

Thanks Stefan,

Much appreciated but having looked more into setting up .asp uploading I'll
hold back until I feel a bit more confident!

There goes my hopes for an easy solution! ;-)

All the best, Andy

Dear Stefan,

What do you mean "multiple File upload form elements"?
by adding more file type elements in the input form?
Of course I tried to one more file element in the form, and it did work any
more.
Did you try and succeeded??
Could you elaborate?
Thank you very much in advance

Stefan B Rusynko · Jun 21, 2005

Yes meant adding
<input type="file" name="File1" size="20">
and
<input type="file" name="File2" size="20">

And set your permissions per
http://support.microsoft.com/default.aspx?scid=kb;en-us;299763&Product=fp2002

No haven't tried since I don't use the std FP forms
- I use ASPupload instead

I use the ASPFileUpload to upload the file, which you posted before in this
thread:
http://support.microsoft.com/kb/299692/EN-US/

There is an example form for postfile.asp

ASP Code
1. Paste the following code to an editor, and then save it as PostFile.asp:
<%@ Language=VBScript %>
<html>
<head>
</head>
<body>
<form enctype="multipart/form-data" action="/?scid=uploadfile.asp&fp=1"
method="post" name="main1">
<input name="file" type="file" size="50">
<INPUT type="text" id=text1 name=text1><INPUT type="text" id=text2 name=text2>
<input name="submit" type="submit" value="Upload">
</form>
</body>
</html>

It doesn't work when I change only the line under the "<FORM" statement:
<input name="file" type="file" size="50"> ,to
<input name="file1" type="file" size="50"> ,
I think the ASPFileUpload.dll recognise only the name="file", nothing else.
Let alone add one more file field to it.

Since my company doesn't have any budget for purchasing software, ASPupload
is not freeware, I can only use the ASP to fix it.
Thank you very much all the same.

ENT

It doesn't appear that code/application is design to allow more then one file to be uploaded at a
time, as it depends in this case if the .dll was written handle multiple file uploads at one time.
