Cakephp: Many to Many Relationship with checkbox

Question

Currently I have two table Products and Orders joined with HABTM. I would like to add the order by ticking product on the list. Below is the code in OrdersController

    $products = $this->Order->Product->find('all');
    $this->set(compact('products'));

Here is the code in orders/add.ctp

<?php 
foreach ($products as $product) 
        { 
            echo "<tr>"; 
            echo "<td class='heading'>".$product['Product']['name']."</td>";
            echo "<td>". $product['Product']['price']."</td>";
            echo "<td class='data'>"; 
            echo $this->Form->input("Product.checkbox.$product", array('label'=>'','legend'=>false,'type'=>'checkbox'));
            echo "</td>"; 
            echo "</tr>"; 
        } 
?>

It display product information and checkbox. When I submit the order, it is not saved into ordersproducts table. Any help would be greatly appreciated.

put an traling dot i.e '.' like this ,this way it will create checkbox name as array..

echo $this->Form->input("Product.checkbox.$product.",
array('label'=>'','legend'=>false,'type'=>'checkbox'));
