How to add simple product to basket if this product is child of configurable product

Question

How to add simple product to basket if this product is child of configurable product ?

How I can get super_attributes of simple product ( I got ID ) to make it ?

An example: I have T-shirts (id 1) configurable product.

And I got XL (id 5), L (id 6) versions of this product.

I want add to shopping cart id 5, but I cannot make it without requestInfo (super_attributes) when I'm using addProduct($productInfo, $requestInfo=null)

Answer 1

Ok , I got it.

Steps.

1. load child product object.

2. load parent id from child id.

3. load parent product object.

4. get parent array of attributes

($parent->getTypeInstance(true)->getConfigurableAttributesAsArray($parent);)

5. Make loop for array of attributes

6. $attributeId = $attribute['attribute_id']

7. And use in loop getAttributeRawValue method for value of attribute.

8. $cart->addProduct($parent, array('qty => 4, 'super_attribute' => array($attributeId => $value)));

9. $cart->save();
