set parent product of the variation as free gift when variation is in the cart

[info17]

How to achieve?
i.e.

product A has variation 1,2,3.
product B has variation 4,5,6.

I’d like to set A as free gift if customer has 1/2/3 in the cart.
And set B as free gift if customer has 4/5/6 in the cart

Do you mean:
If user has 3x a variation of A in the cart, he can choose a free 4th variation of A?
If user has 3x a variation of B in the cart, he can choose a free 4th variation of B?

No, not variation. parent product of variation in the cart.
(means Product A or B itself)
buy Product A variation 1 get free gift Product A(not variation)

I can do this if I specify parent product as free gift if free gift choice is only one.
And I modified cart to be able to choose variation by customer them self there.

But finding the way how to choose from multiple free gift choices automatically.

I don’t think you can add parent products to the cart in WooCommerce.

Actually I can when I set parent product as free gift in Extended Coupon Feature settings.

i.e. Buy 4 Get 1 Free sale

Great, so create 2 coupons. One for product A and one for product B.

I know
but my client want to use same coupon code for couple of products since it’s same product line.
So I’d like to set free goods programmatically depend on parent product of variation.

[Soft79]

I don’t think that’s possible.

What about using this method you mentioned before to set free gift?
WJECF()->get_plugin(‘WJECF_Pro_Free_Products’)->set_session_selected_product( $coupon_code, $product_id )
https://www.soft79.nl/forums/topic/obtain-coupon-info/

Is there way to utilize this method to set free gift programmatically?

[Soft79]

Try this:

Set both product A as product B as a free product in the coupon. Then use filter wjecf_set_free_product_amount_in_cart to change the amount of free products (set to zero if the product should not be applied).

add_filter( 'wjecf_set_free_product_amount_in_cart', function ( $quantity, $product_data ) {
// Logic here
}, 10, 2 );
