I'm on CakePHP 1.3
On my products/index.ctp view I show a menu of categories and list all the
products from the selected category. However I don't want to show categories
where there are no products.
Currently the data comes from my products_controller.php
function index($id = 1) {
$this->Product->recursive = 0;
$this->set('currentcategory', $id);
$this->set('products', $this->Product->find('all',
array('conditions' => array('ProductCategory.id' => $id))));
$this->set('categories',
$this->Product->ProductCategory->find('list', array('fields' =>
array('ProductCategory.id', 'ProductCategory.name'))));
}
What is the best way to only find those categories with products?
Cheers
Paul
