$empty in shopping-cart.tpl

[ed0522]

{if isset($empty)}

<p class="alert alert-warning">{l s='Your shopping cart is empty11.'}</p>

 

I'm wondering why I can't find $empty in orderController.php.

 

In orderController.php, shopping-cart.tpl was set as template.

Did you find out where is the $empty set?

I am trying to find out and cannot find it

Find:

$this->context->smarty->assign('empty', 1);
