Question

I don’t have that much experience with Prestashop, php, and Smarty.
How do I get the category of lastProductAdded?
I am trying to make the “continue shopping” button redirect to the category of the last product added.

<a href="{$link->getCategoryLink($lastProductAdded.category->id)|escape:'htmlall':'UTF-8'}" class="button_large" title="{l s='Continue shopping'}">&laquo; {l s='Continue shopping'}</a>

The following code doesn’t seem to work, giving category id of 0 for some reason. (I have no idea whether it makes sense either)
Any help would be much appreciated. Thank you!

(The variable lastProductAdded and function getCategoryLink are already defined in-built)

For Prestashop 1.4.x you need to modificate Cart::getLastProduct() with this code:

public function getLastProduct()
{
    $sql = '
        SELECT cp.`id_product`, cp.`id_product_attribute`, p.`id_category_default`
        FROM `'._DB_PREFIX_.'cart_product` cp
        JOIN `'._DB_PREFIX_.'product` p ON (cp.`id_product` = p.`id_product`)
        WHERE `id_cart` = '.(int)($this->id).'
        ORDER BY cp.`date_add` DESC';
    $result = Db::getInstance()->getRow($sql);
    if ($result AND isset($result['id_product']) AND $result['id_product'])
        return $result;
    return false;
}
