Access to Variable newsletter Prestashop 1.6

[Carlos]

Hi, I have read that  with $customer.newsletter you can know if a customer is subscribed to the newsletter in Prestashop 1.7 but my website use Prestashop 1.6

 

How can I get that variable?

[Carlos]

Well, after look for several pages I have created an override of FrontController.php  and I have added this code:

 

public function initHeader()
    {
        self::$smarty->assign('customerNewsletter', (int)$customer->newsletter);
        return parent::initHeader();
    }

Now the variable $customerNewsletter is available on header.tpl but always displays 0 for subscribed or not subscribed

 

Any idea how to assign that value?

[Carlos]

Well, I think I have not defined $customer. Now I add this code and it seems is right

 

	public function initHeader()
    {
		$customer = new Customer((int)(self::$cookie->id_customer));
        self::$smarty->assign('customerNewsletter', (int)$customer->newsletter);
        return parent::initHeader();
    }

I have checked with two users and the result is right.
