Release Notes for 3.01

Here's what's new in FormBuilder 3.01 (browse), along with any known issues or bugs still in the works.

NAME

Changes - Changes in FormBuilder 3.0, please also see the README

COMPATIBILITY

For changes between 3.000 and 3.001, skip down to REVISIONS. FormBuilder 3.0 should be completely compatible with FormBuilder 2.x, with the singular exception that you can no longer use the shortcut autoload style of getting to fields:
        $form->field(name => 'category', options => \@opt);
        $form->category(options => \@opt);      # WRONG
The second form is now used to manipulate $form attributes.

INTERNALS

The internals have been completely rewritten, nearly from the ground up. All of the major functions have been split into methods, and objects have been created for the form, fields, messages, CGI params, and so on. Several new sub-modules have been created, including:
        CGI::FormBuilder::Field
        CGI::FormBuilder::Messages
        CGI::FormBuilder::Template
        CGI::FormBuilder::Template::HTML
        CGI::FormBuilder::Template::Text
        CGI::FormBuilder::Template::TT2
Many of these modules can be subclassed and overridden if desired. In addition, the template engine has been rewritten to allow plugging in of additional template modules, simply by specifying the name of the module to the 'template' option in new(). For more details, see the man pages for the individual modules above.

NEW FEATURES

Several new features have been added which FormBuilder 2.x could not support:

Style Sheets

Stylesheets are now generated if the stylesheet option is specified to FormBuilder. This can either be 1 to turn it on, or a full path to a style sheet to include. When used, all tags are then output with a class attribute, named styleclass plus the name of the tag:
        my $form = CGI::FormBuilder->new(
                        fields => [qw/name email/],
                        styleclass => 'myFB',   # default is fb_
                        stylesheet => 1,        # turn on style
                   );
                
        print $form->render;

        # HTML will include
        #   <input class=myFBname id=name name=name type=text />
        #   <input class=myFBemail id=email name=email type=text />

Compliant XHTML

The output should be fully-compliant XHTML finally. Really. Maybe.

Attributes and Field Objects

Individual accessors have been added for every attribute that FormBuilder maintains. For example, here's a snippet of code to demonstrate:
        if ($form->stylesheet) {
            # loop thru fields, changing class
            for ($form->fields) {
                next if /_date$/;   # skip fields named XXX_date

                # each field is a stringifiable object with accessors
                if ($_->options) {
                    # has options
                    $_->class('my_opt_style');
                } else {
                    # plain text box
                    $_->class('my_text_style');
                }
            }
        }
This code checks to see if the stylesheet property has been set on the main $form. If so, then it loops thru all the fields, skipping those named XXX_date. Of the remaining fields, those that have options have their class attribute changed to my_opt_style, and those without options have it set to my_text_style. In addition, you can individually render every part of the form yourself. by calling the appropriate method. For example:
        print $form->header;      # just the header
        print $form->script;      # opening JavaScript
        print $form->title;       # form title
        print $form->start;       # opening <form> tag
        for ($form->fields) {
            print $_->label;      # each field's human label
            print $_->tag;        # each field's <input> tag
        }
        print $form->end;         # closing </form> tag
For a complete list of accessors, see the documentation for both CGI::FormBuilder and CGI::FormBuilder::Field.

Messages

Some messages have been reworded to make it easier to change just a single message, and a couple new messages were added as well:
         js_noscript             <p><font color=red><b>Please enable JavaScript or
                                 use a newer browser.</b></font></p>

         form_required_text      <p>Fields that are %s highlighted %s are required.</p>
         form_required_opentag   <b>
         form_required_closetag  </b>

         form_invalid_text       <p>%s error(s) were encountered with your submission.
                                 Please correct the fields %s highlighted %s below.</p>
         form_invalid_opentag    <font color=red><b>
         form_invalid_closetag   </font></b>

         js_invalid_default      - You must enter a valid value for the %s field
         form_invalid_default    You must enter a valid value
For more details, see CGI::FormBuilder::Messages.

HTML::Entities encoding

HTML character encoding is now dispatched to HTML::Entities, if available. This can be downloaded as part of the HTML::Parser module set on CPAN.

Documentation

Documentation has been updated and somewhat reorganized, which was long overdue.
