Cforms upload validation?
Hi every one
My Form contains upload widgets,
I have limited the size parameter in web.xml upload config.
But I would like to get the oversized error as a form validation error.
In the Form validation docs, it says upload widget supports validation but
no idea of which rules.
Is there a sample for this? a link ?
While digging the net I haven't found anything.
Thanks for the hints
Regards
Tibor

There are no built-in validators for the upload widget except the
mime-type checks. You can however plug an custom validator to check e.g.
the content of the uploaded file.
However, your problem is different and cannot be handled with the
current CForms, and worse, with the current Cocoon as oversized upload
is filtered very early in the request processing, i.e. in the CocoonServlet.
What that means is that the upload widget has no means to know that
upload has occured but was rejected. We need for this to enhance the
multipart handling to pass an indication of the rejected upload to the
application. Note that such indication would be useful also to detect
that upload isn't enabled in web.xml.
Please file a bug for this.
Sylvain
