#76 www_modify breaks if Gizmo validate form

[Lee Weston]

www_modify does not work well with error checking on
forms.

www_save usually ends something like

if ($errormsg) {
$self->www_modify($errormsg);
} else {
$self->save();

#$self->md_redirect("http://$GA{basename}/index.pl?iid=".$self->parent_id);
$self->md_redirect($url);
}

The commented out line is metadot.com's, presumably so
one can edit from a category or the detail. (I use it
a little bit harder, but in the same vain).

The trouble comes in if you do validation on a Gizmo
form and have an error message to display. You go back
into the form (displaying the error message) for the
user to fix things.

... but second time around $url points not to where you
really started, but to the previous modify

In Gizmo
In sub www_modify {

my $target = $SESSION->{referer};

and later

<input type='hidden' name='target' value='$target'>

-----------

it seems to me the assignment line should be

my $target = $FORM{$target} || $SESSION->{referer};

Actaully the fix would be better as

my $target =
defined($FORM{$target})?$FORM{$target}:$SESSION->{referer};
