extend productlazyarray | add property to cart product

[seb776]

Hello,

I want to add a information on cart page.
I'd like to display if a product is payed or offered (discount free gift).

So, I added the information on the template .

{$product.gift}

 

But the property is not defined.
 

So I added, the proper property in ProductLazyArray.php

/**
* @arrayAccess
* @return string */
public function getGift()
{
   return 'gift';
}

 

if I dump the data after the AbstractLazyArray constructor, the gift property is here. ok.

But when accessing it, it is not in the index, despite my code editor does not find any other modification of $this->arrayAccessList .

So {$product.gift} is always empty ...

What am I missing ??

(I know changing core files is not a good practice, how should I do it correctly ?)

Look like it's not possible with ps 1.7.5.1
