Kohana module with tight integration for Phery.js library
Working with AJAX (including file uploads) never been simpler. Just add the phery.js (like <?php echo HTML::script('phery.js'); ?>)
file on your page (or if you are using an assets manager, add PHERY_JS constant to the bunch), and instead of using Controller, use
Phery_Controller and instead of Controller_Template use Phery_Template.
Also, you should notice that the $ajax variable is available in ALL views (but you shouldn't do logic in your views though).
This is mainly useful because you need to do a <?php echo $ajax->csrf; ?> in your head, so you can install CSRF that comes enabled
by default, otherwise your AJAX calls will fail (CSRF stands for Cross Site Request Forgery to avoid remote attacks to your AJAX
forms and/or links)

When you want to make a PHP function available for just one action, you namespace it:
class Controller_Index extends Phery_Template {
/* This will be available for action_index only */
public function ajax_index_edit()
{
return PheryResponse::factory()->alert('works for index!');
}
public function action_index()
{
$form = array(Phery::form_for('', 'edit'));
$form[] = Form::input('id', 1, array('type' => 'hidden'));
$form[] = Form::submit('submit', 'Send');
$form[] = Form::close();
$this->template->content = join('', $form);
}
public function action_view()
{
// calling phery.remote('edit') from the page won't call the phery_index_edit function
}
}When you want to reuse a callback for all actions, just don't namespace it:
class Controller_Index extends Phery_Template {
/* This will be available for action_index and action_view */
public function ajax_edit()
{
$r = new PheryResponse;
/* If you must, check which action the current call should deal */
switch ($this->request->action()):
case 'index':
// do according to index
$r->alert('its for index!');
break;
case 'view':
// do according to view
$r->alert('its for view!');
break;
endswitch;
return $r;
}
public function action_index()
{
$form = array(Phery::form_for('', 'edit'));
$form[] = Form::input('id', 1, array('type' => 'hidden'));
$form[] = Form::submit('submit', 'Send');
$form[] = Form::close();
$this->template->content = join('', $form);
}
public function action_view()
{
$this->template->content = Phery::link_to('Click me', 'edit', array('args' => array('id' => 1)));
}
}You may change the AJAX options per controller, by passing configuration to the ajax function inside your controller:
class Controller_Index extends Phery_Controller {
public function ajax()
{
return array(
'error_reporting' => E_ALL
);
}
public function action_index()
{
}
}Your AJAX function will be processed AFTER your after() function, so you can place all the transformations, cleanups,
in there.
Also, inside the Phery_Controller or Phery_Template, there is the same $ajax variable, so you can mess with Phery youself:
class Controller_Index extends Phery_Controller {
function action_index()
{
$this->ajax->set(array(
'edit' => 'Helper::staticAjaxMethod',
'load' => array(new Model_User, 'load')
));
}
}This make it highly flexible, so you don't need to be tied to convention.
If any exception happens when using AJAX, it will go 'silently' to your application/logs and it will fail with an
empty JSON response {}

$this->ajax->render_view
