Konform - Simple form generator for Kohana 3.3+

Requirements

You'll need the KOtal module, as the views are written in PHPTAL., _(*1)

Usage

Create a subclass of Konform (Konform_Contact, for example).
Set the $_fields property up in your subclass (either in its _init() method, or just at the top of the class).
Create a messages/konform/contact.php file, and populate it with your error messages.
Instantiate your class and use it (see below).
Add some CSS to target these forms, and enjoy.

Examples

Here's a contact form, demonstrating each form element., _(*2)

class Konform_Contact extends Konform
{
    /**
     * Action (location) to submit the form to.
     *
     * @var string
     */
    protected $_action = '/contact';

    /**
     * Other attributes (name => value) to apply to the form.
     *
     * @var array
     */
    protected $_attributes = array(
        'id'    => 'something'
        'class' => 'konform contact',
    );

    /**
     * Fields, keyed on their name, with label, rules, type, and other options.
     *
     * @var array
     */
    protected $_fields = array(
        // Simple text entry box.
        'name' => array(
            'type'      => 'text',
            'label'     => 'Your name',
            'maxlength' => 60,
            'required'  => true,
            'rules'     => array('not_empty'),
        ),

        // One with more validation on it, and a custom CSS class applied to the container.
        'email' => array(
            'type'     => 'text',
            'label'    => 'Your email address',
            'required' => true,
            'rules'    => array('not_empty', 'email'),
            'class'    => 'email',
        ),

        // Example of a select element.
        'group' => array(
            'type'         => 'select',
            'label'        => 'Person or group',
            'required'     => true,
            'rules'        => array('not_empty'),
            'placeholder'  => 'Please select...',
            'optionSource' => '_getGroups',
            'optionValue'  => 'pk',
            'optionLabel'  => 'name',
        ),

        // And a textarea.
        'body' => array(
            'type'     => 'textarea',
            'label'    => 'Your message',
            'required' => true,
            'rules'    => array('not_empty'),
            'cols'     => '70',
            'rows'     => '10',
        ),

        // Don't forget to add a submit button.
        'submit' => array(
            'type' => 'submit',
            'label' => 'Submit',
            'class' => 'buttons'
        ),
    );

    /**
     * Get the groups for the dropdown list.
     *
     * These source methods must return something iterable (suitable for reading
     * by foreach - arrays, Iterators, etc).
     *
     * @return Database_Result
     */
    protected function _getGroups()
    {
        return ORM::factory('group')->find_all();
    }
}

And, here's the controller code to go with it., _(*3)

public function action_index()
{
    $contactForm = new Konform_Contact($this->request->post());
    if ($this->request->post() && $contactForm->validate()) {
        // Looks like we received valid data, so send the emails.
        $this->_sendContactEmail($contactForm->data());
        HTTP::redirect('/contact/thank-you');
    }

    $this->response->body($contactForm->render());
}
