Hi!

I have a form with a file-input tag. Now, how do I determine if there is actually a file upload done?
(I tried to read the file size with
<dtml-if "_.len(file.read())">
 there is data
<dtml-else>
 there is no data
</dtml-if>

But this does not work (always 0).

Ok, how is this to be done?

Regards, Ingo.
