Quick question on how to get product quantity

[keepyourhead]

Hi at all! I'm new to PrestaShop.

I need a very very quick thing.

I have the Product ID. As you can see in the attached screenshot, I have colours and sizes for that product.

I need to get the product availability (quantity) for each color, for each size.

And I need the TOTAL availability (all colors and sizes). How can I do this?

I tried with getAttributesGroups , but I'm not able to distinguish colours (it gives me the product quantity for sizes, but I have nothing to say "this is color black", "this is color white", etc...). Even though I'm filtering by id_attribute_group !!

Can someone more experienced than me give me this advice?

This is a very quick thing and I need it. I have no need to learn PrestaShop. I have the need for this thing:

Thanks in advance!!
