Re: Selecting products that are found in the selected category.

Where in your controller are you attempting to run any finds with conditions using the category or product id?

Hey everyone,

I have a page where you can add products to a list, on that page i
want a select for the categories and a select for the products, if the
categories select is changed i want the products select to list all
the products in that selected categorie.. I tried some of the info i
found on the internet but i wasnt able to fix this..

This is the code of the controller:

<?php
class OrderLinesController extends AppController {
    var $name = 'OrderLines';

    public function index() {

    }

    public function view() {
        $orderline = $this->OrderLine->find('all');
        $this-
>set(compact('orderline'));
        }

    public function add() {
        if ($this->request->is('post')) {
            if (!empty($this->data)) {
                //$this->OrderLine->create();
                //$this->OrderLine->save($this->data);
                echo $this->Session->setFlash(__('Orderline
succesfully registered'));
                //$this->redirect(array('controller' => 'orderlines',
'action' => 'view'));
            } else {
                echo $this->Session->setFlash(__('Please fill in all
fields'));
            }

        }

        $categories = $this->OrderLine->Product->Category-
>find('list');
        $this->set(compact('categories'));

        $products = $this->OrderLine->Product->find('list');
        $this->set(compact('products'));
    }
}
?>

The model:

<?php
class OrderLine extends AppModel
{
    var $name = 'OrderLine';
    var $belongsTo = 'PersonalOrder';
    var $hasOne = 'Product';
}
?>

And the view called add.ctp:

<?php
    echo $this->Form->create('OrderLine', array(
        'action' => 'add',
        'name' => 'cat_select'
    ));
    echo $this->Form->input('category_id', array(
        'type' => 'select',
        'style' => 'text-transform: capitalize',

    ));
    echo $this->Form->input('product_id', array(
        'type' => 'select'
    ));
    echo $this->Form->submit();
    echo $this->Form->end();
?>

Thanks.
