Hi,
I'm the beginner in Cake but can you try this code:
function admin_index($id) {
$this->Product->recursive = 0;
$products1 = $this->Product-
>findAllByCategory_id($id);
$this->set('products', $products1);
if(array_key_exists('category_id',$products1)) {
$this->data['Category']['id'] = $products1[0]
['Product']['category_id'];
} else {
$this->data['Category']['id'] = $id;
}
}
I think that $this->set function create a variable in the view and you
can't use it in the controller.
