Hi,
The syntax if form.vars.pic_upload: worked for me. I was not able to find

@ Steve : No I have not used the IS_NOT_EMPTY() validator. Thanks for the
link I will go through it.

else:
#do whatever you want

Hi,
I have a problem with checking whether the file upload field in the
database is empty or not.
In the code mentioned below, the user can either upload a file or submit
the form without uploading a file.
If the user uploads a file then the " makeThumbnail" function should be
called. Otherwise it
