get attribute names from $id_product_attribute variable

[shpetimi]

Is it possible to get attribute names in the priceCalculation() function inside the Product.php class based on the $id_product_attribute variable? what could be the mysql query for this?

[vekia]

if you've got an id of attribute you can just simply use Combination class

$combination = new Combination($id_product_attribute);

then $combination variable will store each available combination object definition

Thank you Vekia, I tried the Combination class with print_r($combination) and as I can see there it doesnt fetch the name column from the attribute_lang. Because I need the attribute names. Basically I am trying to change the PriceCalculation() function. so in order to do that I need the attribute names because the calculation formula that I am trying to implement depends on the selected attributes (2 selected attributes) to show the price in cart, etc.. In the product page it works because I implemented this with javascript. But I need to fetch the selected attributes to show the price based on those attributes. (Note: I am not using prestashop default combinations).

$combination = new Combination($id_product_attribute);

$arr = $combination->getAttributesName($id_lang);

p($arr);
