adding items to cart

[eluser]Unknown[/eluser]
I have a controller that loads the cart library and then has a function to add an item to the cart.

Code:

function add($id, $qty, $price, $name)
{
     $data = array(
           'id'      => $id,
           'qty'     => $qty,
           'price'   => $price,
           'name'    => $name,
           'options' => array('Option1' => '1')
        );

    $this->cart->insert($data);
}

This function works fine if the name of the item is one word. However when I exceed one word for the name it won't add the item to the cart.

I am running this function through an AJAX request and I have tried encoding the URL but that doesn't seem to work.

Thanks for any help.
