cakephp unable to load a mobile view - cakephp

Question

I am trying to load a separate mobile view and having a problem.
I can get my mobile layout to work but not the view.
I was using this question as a reference and I am running cakephp 2.1
CakePHP website mobile version
I am not sure how to structure my mobile views?
Is it /app/View/name/mobile/view.ctp or
/app/View/mobile/name/view.ctp or something else. I have been going in circles trying to figure this out. Any suggestions.
My AppController.php
Before Filter
public function beforeFilter() {
/* mobile layout testing */
if ($this->request->isMobile()){
$this->is_mobile = true;
$this->set('is_mobile', true );
$this->autoRender = false;
} else {
$this->set('is_mobile', false );
}
}
After Filter (shortened)
function afterFilter() {
$view_file = file_exists(
"/var/www" .
$this->webroot .
"app" . DS .
'View' . DS .
$this->name . DS .
'mobile/' .
$this->action .
'.ctp'
);
$layout_file = file_exists(
"/var/www" .
$this->webroot .
"app" . DS .
'View' . DS .
'Layouts' . DS .
'mobile/' .
$this->layout .
'.ctp'
);
if($view_file || $layout_file){
$this->render(
$this->action,
($layout_file?'mobile/':'').$this->layout,
($view_file?'mobile/':'').$this->action
);
}
}

Answer 1

In previous version(s) of CakePHP, $this->render() had three parameters, but in 2.x and beyond, it only has 2:
CakePHP 1.3 API for Controller render() - has 3 parameters:
http://api13.cakephp.org/class/controller#method-Controllerrender
CakePHP 2.0 API for Controller render() - has only 2 parameters:
http://api20.cakephp.org/class/controller#method-Controllerrender
Becuase of that, your answer utilizing only 2 parameters works much better than your attempt with 3. :)
(The CakePHP Book still incorrectly states that there are 3 parameters, so - I certainly don't blame you for trying as it's mentioned - had to look it up in more detail to find this out)

Answer 2

I ended up doing this below. My view folders now check for a mobile folder and load the view if it exists.
function afterFilter() {
// if in mobile mode, check for a valid view and use it
if (isset($this->is_mobile) && $this->is_mobile) {
$has_mobile_view_file = file_exists( ROOT . DS . APP_DIR . DS . 'View' . DS . $this->name . DS . 'mobile' . DS . $this->action . '.ctp' );
$has_mobile_layout_file = file_exists( ROOT . DS . APP_DIR . DS . 'View' . DS . 'Layouts' . DS . 'mobile' . DS . $this->layout . '.ctp' );
$view_file = ( $has_mobile_view_file ? 'mobile' . DS : '' ) . $this->action;
$layout_file = ( $has_mobile_layout_file ? 'mobile' . DS : '' ) . $this->layout;
$this->render( $view_file, $layout_file );
}
}
