Don't worry I am a self-taught PHP hack and learned the hard way, but
I must admit you're adventurous for tackling a RESTful app whilst at
the bottom of your PHP and CakePHP learning curve.
When it comes to passing variables/arrays from the controller to your
view you can name them whatever you want, there are no conventions at
that point as long as you use the same array name in your view as you
set in the controller.
If you're saying your controller action is stopping at
function search() {
if(empty($this->data)) {
$this->render();
Then you're not passing your search term from a field with a name of
data[Partner][q]. Cake will only place form data in the $this->data
array if you post fields with a name format of data[ModelName]
[field_name]; You can see if your search term is elsewhere in the
request params by using echo debug($this->params);
Past this point your code does the following:
$partners=$this->Partner->find('all', array('conditions' =>
$conditions));
// sets a $partners array in the controller
$this->set('partners', $this->paginate());
// sets a paginated $partners array in the view
$this->set('partners', $partners);
// overwrites the view's paginated $partners array with the array you
set in the controller previously
So with this code you should have a $partners array in the view
containing the results of:
$this->Partner->find('all', array('conditions' => $conditions));
What do you get if you echo debug($partners); in the view?
HTH, Paul.
