Can't have the Cart total for a CartRule

[Mehdib92]

Hi,

 

I'd like to change the way that the cart rule works.

 

In order to do that, I check if the cart rule's reduction amount is higher than the cart total for the products. 

 

If it's the case, it use product + shipping instead of only the product.

 

But in my CartRule.php class, if I want the result of getOrderTotal($use_tax, Cart::BOTH) (or even getOrderTotal($use_tax, Cart::ONLY_SHIPPING)),  instead of getOrderTotal($use_tax, Cart::ONLY_PRODUCTS), I have a Fatal error : memory limit, even if I put the memory limit to 512Mo.

 

How can I know where it comes from ?

 

Thanks
