possible bug in CGI::FB::Field

Hi,

In CGI::FB::Field::value(), line 186, a manually supplied value is 
passed through cleanargs().
This has the effect of changing a single value into a hashref, and has 
the side effect of turning on the 'multiple' flag in a select widget.

While I'm here, the website seems to be down.

Cheers,

d.

Ok, I see where you're pointing. Can you send me a snippet that 
illustrates this?

I can't quite convince myself this is a bug. Seems to be that if I 
partially build a field, and then later on, try to set its value, the 
problems occur. I can get around this in my app, which suggests it's my 
usage that's wrong. Still, cases 3 and 4 in the two scripts attached 
seemed to be almost reasonable behaviour, and they show the problem.

Yeah, it's a bug. Using cleanargs() there is a mistake. I just fixed
this in the 3.03 tree by splitting cleanargs() into arghash() and
arglist()  (since some subs want hashes and others arrays).

In the meantime, in the script, you can do this:

   $form->field(name => 'foo', value => ['bar']);

And that will have the desired effect, without setting 'multiple'.

Selecting 0 in select list yields nothing

I'm using CGI::FormBuilder v3.0202, CGI v3.09, and Perl v5.8.6.

I'm having problems with a select list.  The application sometimes
needs to collect the user's height in feet and inches.  I set up the
code like this:

if(defined($height_collect) && $height_collect)
{
	my $reqd = 0;
	my $label = "Height";
	if(defined($height_required) && $height_required)
	{
		$reqd = 1;
	}
	else
	{
		$label .= " (optional)";
	}
	$form->field(name => "height_feet",
				 label => $label,
				 comment => "Feet",
				 options => [ 1 .. 8 ],
				 );
	$form->field(name => "height_inches",
				 label => "",
				 comment => "Inches",
				 options => [ 0 .. 11 ],
				 # This could be "0"
				 # which will otherwise bust validation.
				 validate => 'INT',

use javascript

I use template file, and there are two dropdown lists in my form (products and 
builds).  The sencond dropdown list (builds) depends on the user's selection on 
the first list.  So I tried to use javascript, in my cgi file, I initilaized 
the product list:

$form->field('name'    => 'product',
               'onchange' => 'filter_builds()',  #assign JS function here
               'type'    => 'select',		
               'options' => \@product_cache);

in my tmpl file, I tried both to insert the javascript code or use external js 
file.  But it doesn't work in either way.  

   Anyone has idea how to use javascript in such case? Thanks in advance.

Formbuilder, HTML Template and multiple forms on one page

Hello,

I've recently started using formbuilder in conjunction with HTML Template to 
make templated forms.  I've come across a situation I'm not quite sure how to 
handle.

I'm trying to have one template file (let's say example.tmpl) and that 
template file may or may not include other templated files (shouldn't be 
relevent for this question).

So here's the deal.  I'd like to have multiple forms on the page output by 
example.tmpl but I'm not quite sure the best way to do that with formbuilder.  
HTML Template only has <tmpl_var form-start> and doesn't seem to allow any 
way to distinguish forms (e.g. a name="formname" attribute).

Now it appears I could template out a header, than create a new form instance 
for each form and close it with a footer template.   That's a bit awkward and 
would also break formbuilders javascript validation (since the <script> tags 
couldn't be included in <head></head>).  There's got to be a better way to do 
it than that.  

Many sites have a login area on one form and a poll on another form all in the 
same page (i.e. www.slashdot.org) so it is a pretty common situation.  I just 
can't seem to figure out the formbuilder/HTML Template way of handling it.

Thanks.

other doesn't work with multiple

Hi,

I think I have found a bug, in that the following does not work correctly:

$form->field(
        name    => 'abc',
        options => [ 'foo', 'bar'],
        type    => 'checkbox',
        other   => 1,
),

If you add something in the "other" field and also selects one or more
of the static items, the other field is greyed out - even if you
deselect those static items again. At least that's the case with Mozilla
Firefox as of today (in case this is something browser-specific).

You'll probably need to pass your $form object into each sub. Without 
seeing the code I'm not sure exactly what's going on, but you should 
probably have something like this:

    use strict;

    sub create_form {
        return CGI::FormBuilder->new(%options);
    }

    sub display_form {
        my $form = shift;
    }

    sub validate_form {
        my $form = shift;
    }
