[Zope] No file in INPUT TYPE='file' field

[Mabe, Brad]

I love this list!  I am designing a file upload form and just started
thinking about how I am going to handle invalid filenames, no filename, etc.
Of course, rather than doing "real work" I decided to take some time and
catch up with my e-mail and viola! Here is this thread.

Thanks Peter!

Hi

I use this code to check if the input is empty:
<dtml-if "name_of_file_input.filename">
Exists...

To check if the input is a valid file you can store it as a temporary
variable and then make a check if the size of the object is more than 0
bytes like this:
<dtml-if "_.getitem(temp_object_id,0).getSize() > 0">
Valid file...

I hope this helps you :)

Peter
