It is possible build form pages that include file upload fields that are not required.
If you are using "Option Explicit" to requeire variables to be declared the ASP Upload code is working normally
There is no need for any other components or special access to the server!
An Upload report is send to the redirect page.
Upload report
The redirect page receive, in the post, this field for each file uploaded:
- FileName
- FileLength
- FileStatus
- NewFileName
To separate the single file value (for multiple upload file) to each variable I add a progressive number.
FileStatus value:
|
| 0 | No problem | Saved |
| 1 | File size exceed | Skipped |
| 2 | File extension not allowed | Skipped |
| 3 | File extension not allowed and File size exceed | Skipped |
| 4 | File exist | Skipped |
The NewFileName
variable can be "0" (If my code don't modify the file name) or "-1" (If my code modify the file name this option is applied if You use the "Unique name" in the Conflict Handling options)
An optional field is send to the redirect page: "NumFile
" that is the number of file Uploaded
To see an example of the redirect page click this link
If you set the Total file size
value and the sum of the size of the uploaded files exceed the files will not be saved and 2 parameters will be send to the redirect page in the post parameters.
The 2 parameters are:
UploadedSize:
The sum of the size of all the uploaded files
MaxFileSize:
The max size allowed for the upload (The value of the field Total file size
)
Files List
The list of the File Field in Your form.

Progress Bar
Total file size
File upload size can be limited for each file or for the sum of all the uploaded files.
This field is the file size limit for the sum of the uploaded files.
It can be limited on the server side (after upload)
If this field is void no limit size are applied.
All this features are for each file!!!
Upload Folder
Relative:
a Path relative to the Site or to the Document
ex: /MyFolder/
ex: //MyFolder
Use the search button to find Your Upload Folder
Absolute:
an Absolute Path
ex: c:\MyFolder\
With this You can save the file outside Your web site. Simply write the full path on the server as your upload folder!
Dynamic:
a dynamic path
ex: server.MapPath("/MyFolder" & Session(User))
In this case You must enter all the ASP code to
define Your Upload Path
You can make the upload folder name by including other form fields! For each field you use UploadFormRequest instead of Request.Form
File Name
The name of the file uploaded.
All invalid characters used in the filename of the uploaded files are automatically removed. Only letters, numbers and _-. are allowed.
Allowed Extension
You can select which file extensions you want to allow your users to upload.
If this field is void no reTransitionalion are applied.
It can be limited on the server side (after upload) and on the client side (before upload).
To select which file extension you want to allow you must enter the list of extension/s separated by comma.
ex: .txt,.doc,.pdf
Max File Size
File upload size can be limited for each file or for the sum of all the uploaded files.
This field is the file size limit foreach uploaded files.
It can be limited on the server side (after upload) and on the client side (before upload).
The file that exceed the size are skipped

Max Dim If Image
The pixel Image dimensions can be limeted!
It can be limited on the client side (before upload).
If one of them exceed the dimension the Upload don't start.
Tha value are in Pixels.
You can limit only Width, only Height or the two dimension.
If this field/s is/are void no limit are applied.
The test if image is on the file extension's.
Conflict Handling
Should a file already exist on the server, you can specify how you would like to handle the new file. Choices include overwriting, giving the file a unique name and skipping the file.
If You select "Unique name" and a file exist my code add e progressive number to the file name.
ex: Existing file is MyFile.txt the new name will be MyFile0.txt
