Question

I am using Kohana version 3 and would like to modify a form input field. I am having troubles understanding how this works in kohana. Is the input done by a controller or a helper? What do Controllers and helpers actually do in Kohana?

thanks for any advice,

Rob

Generally, I would use the Kohana form helpers to build the HTML tags for the form and fields, and pass data into these helper methods from the controller.

For example, in my view views/contact.php:

<?php echo Form::open()?>
    <fieldset>

        <div class="field">
            <?php echo 
                Form::label('name', __('Name')),
                Form::input('name',  $name)
            ?>
        </div>

        <?php echo Form::submit('save', 'Save')); ?>
    </fieldset>
<?php echo Form::close()?>

In controller classes/controller/contact.php

class Controller_Contact extends Controller {

        public function action_index()
        {
                $view = View::factory('contact')
                        ->set('name', 'Richard');

                $this->response->body($view);
        }
}

Adding that data to a table in the db is a bit more complicated, but generally you would use a model to do that. Have a read through the ORM documentation: http://kohanaframework.org/3.2/guide/orm

A controller would handle the request data and would interact with the model to save the data to the database.

Here’s an example of that process: Kohana ORM and Validation, having problems
