In case the index controller is useful, here it is.
function index($categoryID = null) {
if (!empty($categoryID)) {
App::import('Model','Category');
$cat = new Category();
$category = $cat->field('title', array('id' =>
$categoryID));
$this->set('category', $category);
$this->set('categoryID', $categoryID);
$conditions = array(
'conditions' => array(
'Category.id' =>
$categoryID),
'order' => 'Subcategory.order
ASC'
);
$subcategories = $this->Subcategory->find('all',
$conditions);
} else {
$this->set('category', 'All');
$conditions = array(
'order' => array(
'Category.title' =>
'ASC',
'Subcategory.order' =>
'ASC'
)
);
$subcategories = $this->Subcategory->find('all',
$conditions);
}
$this->Subcategory->recursive = 0;
$this->set('subcategories', $subcategories);
}
