Hi,
I think I have found a bug, or at least an undocumented feature. If the query string
contains a field with a 0-length value (i.e. the empty string) Embperl does not pass
this into %fdat, instead, it leaves it not existing in the hash (effectively
undefined).
For example: ?entry=&foo=bar and ?foo=bar both result in $fdat{entry} not existing,
when what should happen is that $fdat{entry} is "" in the first case.
This makes it impossible to distinguish between the user entering an empty value and
the field not being present. This is often seen when you have a page that can be used
to add an entry and modify an entry where the identifier being present is used to
determine if you should be adding or modifying, for example:
modify existing item "foo":
item.html?entry=foo
add new item:
item.html
All ok, until you have the situation where you can have the empty string identifier:
modify existing item "":
item.html?entry=
Best wishes, James
