The problem with using:
[% cgi.params.carton != 'on' %]
is that I can't tell if the carton checkbox really was unselected. The
above code would be true if I did unselect it. Or it would also be true
if I hit the page by typing the URL into my browser. I need to be able
to tell that for sure the checkbox was unselected.
Is there no way to tell if a key exists in a hash? Even if it contains
''.
Or is it that the cgi module always returns '' instead of undef if a key
doesn't exists in cgi.params.
For now I've done the following:
[%
IF cgi.params.size != 0 && cgi.params.showcart == '';
### It has been deselected
END;
%]
Can anybody think of a better (more correct) approach?
Thanks,
