Custom input file ?

[deemoox]

Hi,

I would like to use input type file, but i would like to put any file in it
when i go on the page for example when user go back after try to submit

imagine any form to fill for send information...b ut after the user
validate....one on the fields is bad...then the user must be correct this
field.....But i don't want another fields are empty. The user must just
correct one fields and keep another fields


any idea ?

Yes.

If you, some author of some webpage, were allowed to add random files to the
upload, why not add all kind of files on the client's system?
And send them to your server without that person's approval.

So it is a securityprecaut ion.
The uploadfunctiona lity is crippled on purpose.
I expect all serious browsers to stop javascript from adding files to the
upload.

I think you have to look at a workaround.
Maybe let the user upload files AFTER all the other data is checked?

Good luck,

Of course there are other solutions!
There are always other solution.

You could eg store the current state (old form-info) in hidden variables in
the screen with the upload-element.
so:
1) your first part checks all the forminfo.
If it is not okay, return it to the user and ask him/her to correct it.
2) when you are satisfied with all the data, offer the upload, and send all
the other info too as hidden variables.
You don't even have to change the receiving script that way, only add a
checkingscript before it that produces the uploadform when all is accepted.

Maybe I am missing some crucial point over here, not sure.

just my 2 cents.
